A development often used in buddy films and romantic comedy. One person, often a loner-type, is paired off with someone else against his/her will.
He can't stand the person/situation and wishes for his old routine. When he gets his old routine back, he suddenly realizes he misses that person a lot and does everything in his power to get her back. Usually, happens when a bickering pair become Vitriolic Best Buds, or generate an Aww, Look! They Really Do Love Each Other situation, whether it's a fraternal sort of love among buddies, or romantic love.
Sometimes subverted to "Can't live with 'em, can't kill 'em".

Ranma ½ has Ranma and Akane. Once he had disappeared she was depressed and cried when she thought nobody was looking. When Ranma thought Akane was dead after touching one of the Saffron's devices, he was completely apathetic and emotionless.
InuYasha: Pretty much the same example as the above for InuYasha and Kagome. All they ever do is fight, mostly leading to Kagome storming off after a massive sit. However, anytime they're seperated for too long, all Kagome can think about is InuYasha, while InuYasha will be unbearable to be around until Kagome's back. And in any fight, they will put themselves in any kind of danger to save the other (which more than half the fight is of InuYasha taking all those moutain busters to keep everyone else safe).
Full Metal Panic!. Kaname Chidori spends every waking moment berating Sousuke for whatever screw-up he made. The second he is redeployed and out of her life for good, she suffers bouts of depression, paranoia, and a horrible sense of insecurity. Of course, she was being marked for death at the time, which makes this a literal case of "Can't live without him."
Every third waking moment. She spends a similar mount of time trying to prevent and/or renumerate his messups. The remaining time is spent dreading what will happen next.
She was also pretty moody when Sousuke was called away for a long mission to Helmajistan ("The Wind Blows at Home, Part 1-3"), even sitting outside his apartment until he returned.
Mazinger Z: For all what argue when they are together -and claim they don't need each other-, Kouji and Sayaka tend to lose it when they are apart.
Midori Days. Midori becomes Seiji's right hand and remains this way for the majority of the series. Eventually in the manga, however, Seiji does become quite capable of living with Midori and acknowledges this, although she ends up disappearing anyway.
Neon Genesis Evangelion. So very very true with Shinji and Asuka. Up to the point that Shinji ends the world when he discovers' Unit 02, and probably Asuka's half-eaten corpses as he just arrived to try and save them. The series ends with Shinji and Asuka looking out over a devastated earth, as the last two people in existence. Or maybe the first two. OrSOMETHING!
Word of God said she returned together with him because -despite of how much they had hurt each other- he did not want living in a world with no Asuka.
Rozen Maiden. The protagonist just wants to be left alone, and he hateslittle kids. Before you can blink, he's got a small army of childlike, living dolls hanging out in his room, one of whom enjoys ordering him around like a servant, while the rest tend to merely be noisy with a penchant for wanton property damage. Of course, in the end, when they all leave, it gets rather lonely all of a sudden... Fortunately, they're only gone for 'bout half an hour.
Bludgeoning Angel Dokuro-chan. This trope occurs despite the fact that the titular character spends most of her time "accidentally" killing the male lead and then reversing the process, (and that's "accidentally" with a large helping of sadistic glee).
In The Wallflower manga, womanizer Ranmaru tries to get out of a date with a sweet, timid girl, as he prefers assertive women. Of course, after he succeeds, he realizes that he actually likes her.
The morning after Morinaga takes advantage of a doped-up Souichi in The Tyrant Falls in Love, the extremely homophobic Souichi attempts to murder Morinaga, and yells that he doesn't want to see his face again. When Morinaga takes his declaration to heart and disappears from his home and university for weeks, Souichi predictably falls apart. Of course, with his tsunderish personality, his first action upon seeing Morinaga back is to punch him hard and scream at him for hiding himself for so long.
Kyon from the Haruhi Suzumiya series constantly, constantly complains, rants and grumps about Haruhi and the SOS Brigade. In the 4th novel of the series, he is finally freed from Haruhi and the SOS Brigade, only to realize that he actually misses Haruhi. Or just the "weird events", who knows... After a Red Pill, Blue Pill decision, he returns.
He never stops his cynical snarking, but he seems to see Haruhi in a different light (and appreciates her good deeds). He also does stand to his decision, repeatedly saying that he "wanted to be here", creating a True Companions-like relationship.
Eva from Monster spends a good bit of time plotting to make Tenma's life a living hell (getting him imprisoned and such), although every now and again she'll remember that she loves him and beg him to come back to her. She broke up with him, incidentally.
In the Jdrama, Nobuta Wo Produce, Shuji says he hates Akira, but the two are actually very good friends. Maybe too good...?
In XXX Holic, Watanuki is shown to normally get extremely frustrated with Yuuko, and keeps yelling that he can't stand the way she is. And then... she disappears, and he completely breaks down, tears and all, revealing exactly how important Yuko had become to him. This results in him getting extremely depressed, and making a pact to wait for her in the shop forever, never aging, and never being able to leave, until she comes back to him. He even takes on some her traits like smoking from her pipe, and dressing in her extravagant clothes, as if he's trying to cling onto whatever he's got left of her. Let's just say that Doumeki is not pleased to hear this...
Natsu and Gray, from Fairy Tail. They pretty much complain and fight but do admit to themselves they respect the other. Heck in the Galua Island arc when Gray twice tries to use Ice Shell, a spell that will turn the user into ice to trap their opponents. Natsu stops him both times spelling out that he doesn't want Gray to die.
Yuuri and Wolfram in Kyo Kara Maoh!. Yuuri spends the first two seasons trying to back out in an engagement that he accidentally caused in the second episode when Yuuri first enters the other word. Both of them hate the idea at first but Wolfram accepts his role as he constantly tries to get Yuuri to accept his as his husband. Yuuri constantly plots breaking the marriage on multiple occasions but always fails because Yuuri simply doesn't understand the demon world. However, the small things that piss Yuuri off at the beginning of the series, which range from Wolfram calling him "Wimp" (this was originally his Berserk Button at the beginning when the two argued each other) and Wolfram going everywhere declaring himself the spouse of Yuuri and accusing him of Yuuri cheating on him with every girl he meets. However, as the series goes on, the small things that annoyed Yuuri at the beginning is met with indifference as he slowly gives up on trying to break up the engagement. However, once season 3 hits and Wolfram calls the engagement off, this actually shocks Yuuri to the point where he works to get Wolfram back and then finally declares that he's not allowed to break it off. This is a sign that Yuuri is still confused with his feelings for Wolfram but won't let him design things on his own. Shortly after though, they fall right back into the roll.
In Wild Rose, Kiri and Mikhail don't get along initially and like to anger the other. Since Kiri literally can't live without Mikhail because he otherwise loses his sanity around humans, they are stuck together. Over time they both come to appreciate each other in spite of their differences and in the end Mikhail hesitantly admits "You are necessary to me" in response to Kiri's Love Confession.

Hunter and then begins to rise up the ranks, the tension gets worse because they're always encountering each other...and discovering to their dismay that they work well together. Pretty much everybody that knew them saw what was happening before they did, though.
Tomoe and Nanami from Kamisama Kiss. Tomoe is a Kitsune that has been forced to serve Nanami against his will and is typically very rude and condescending towards her. Nanami thinks he's a Jerk Ass in return. However, should anything happen to Nanami he freaks and should another man take interest in her watch out. Meanwhile, Nanami hasn't bothered to hide the fact that she has developed feelings for Tomoe.
Sangatsu No Lion has a downplayed variant of this. Due to his past, Rei's very persistent in living independently. He's also reluctant to get close to the Kawamoto family, despite their willingness to welcome him into their home, and will sometimes abstain from visiting when he has the choice. However, when he returns to his apartment after staying in their house and living with them for several days due to sickness, he's become much more aware of how empty and quiet his own place is.
Rei: "That house is like a kotatsu. When you go inside, it's so warm it feels like you're about to melt...But when you leave, you'll be reminded that your everyday life that felt fine before is freezing cold."
LightYagami of Death Note seems to have this relationship with L to some degree. He spends much of their time together monologuing about how much he hates L and how many of L's strange quirks drive him crazy, until he actually manages to kill L. After that... Light doesn't hate him anywhere near so much, and even seems to miss him to some degree.
Not only that, but L is the person Light sees standing by his side as he's dying.
Mahiro from Haiyore! Nyarko-san gets easily annoyed by how clingy and off-the-wall his alien Pretty Freeloaders Nyarko, Cuuko, and Hasta are, but in the finales of both TV series he gets a harsh reminder of what life would be without them. In the first season finale, he's put in a "Last Man on Earth" situation and realizes how lonely he is; in the second, the trio is about to be reassigned away from Earth, and hearing a heartbroken Nyarko say "Does this mean I have to leave Mahiro forever?" makes him realize that he's about to lose them for good. After the latter situation is resolved, Mahiro remarks "I get the feeling you three will always find a way to stick around me," but it's obvious he views that as a good thing.
Jeremy and Ian from A Cruel God Reigns. Jeremy tells Ian that he needs to see him because Ian is the only one to know that he is a murderer and why he did it. To the point that when they do not see each other Jeremy just aboutloses it.

The Second Try: Shinji and Asuka. This was apparent in the series to everybody except them, but in the fanfic they became aware of the fact during the After the End chapters (and Asuka is particularly hit hard by it). When one of them is missing, the another gets worried and upset. When they are neither talking to each other nor sleeping together cause a fight, they miss each other. And both are terrified of the possibility of breaking up and going separate ways after a dispute.

The Muppet Movie has a song called "I Hope That Something Better Comes Along", sung by Kermit and Rowlf and referring to Miss Piggy (and, by extension, women in general). It opens with the lines, "You can't live with 'em / You can't live without 'em..."

Sam Fuller: ... no, that's pretty much it.
Gracie Hart: Yeah.

In the Discworld novels, Granny Weatherwax is less than thrilled with having to take part in a witch's coven, not least of all because the maiden of the coven, Magrat, keeps annoying her by being a Genre BlindWide-Eyed Idealist. Yet, when Magrat leaves the coven after Lords and Ladies she grows despondent with the whole thing since she hasn't got anyone to boss around or quarrel with, which sets in motion the events of Maskerade.

Fisk seems to have this relationship with Michael in the Knight and Rogue Series (Michael is too sweet to not stand Fisk).

Acording to Michael, Fisk will try to protect him from anything from the noose to chills, all while being insultingly sarcastic.
Sisterhood Series by Fern Michaels: This seems to happen between the Vigilantes and their boyfriends. In one book, Jack Emery makes a comment about women and how you can't live with them and you can't live without them. A short time later, Nikki Quinn makes a comment about men and how you can't live with them and you can't live without them. At least the feeling is mutual!

In Dexter, the title character says of his adopted sister who crashed at his place for a while after some troubles: "Can't live with her, can't kill her." As Dexter happens to be a serial killer, the second half of the phrase takes on a different meaning. He was joking though because he is "rather fond" of her.
In Scrubs, Dr. Kelso initially couldn't stand his wife's snoring. She got the operation, but (this being Scrubs) only exacerbated the problem. Cue this trope:
Kelso: Here's the twist. Now, whenever she goes out of town, I can't fall asleep without the sound of that gasping, wheezing woman lying right next to me. Trust me. If I ever met a Japan air stewardess who snores like Enid, I'd marry her tomorrow.
Dr. Cox and his ex-wife Jordan have this sort of relationship. Both are snarky, jerkass misanthropes who can't stand each other...and it's made abundantly clear that they'd never be happy with anyone else.

"First he'll kill her, then I'll save her / No, I'll save her, then I'll kill her!"
Oz. A black inmate on Death Row is subject to constant racist taunts by a redneck in the next cell. After first breaking his hand when he punched the wall in frustration, he then gets smart and carefully digs a hole into the wall, then after one comment too many punches his fist through what's left and throttles the redneck to death single-handed. Unfortunately that means he's the only inmate left on Death Row, and the episode ends with him looking sadly into a hand mirror, with only himself for company.
Ross and Rachel from Friends. If they're with other people, they want each other: If they're together they argue constantly and break up. Rachel is especially bad as at one point she manipulated Ross into breaking up with his current girlfriend and then refused to get back together with him unless he took all the blame for a past break up. (He didn't).
The actual line was parodied twice on 3rd Rock from the Sun. In the pilot, Harry declares "Women, you can't live with 'em... and yet they're everywhere." In a later episode, Dick declares "Women, you can't live with 'em and you can't have heterosexual sex without 'em."
To which Harry responds, "That's probably true."
Also in one episode Judith says to Mary, "Men, can't live with 'em" [beat while Mary waits for the rest] "Goodbye, Mary."
Norm, of course, subverts the line in Cheers: "Women. Can't live with them, pass the beer nuts."
The Vampire Diaries: Damon and Elena, until the last four or so episodes of the first season. After that, they drop the "can't stand them" part.
Pretty much the reason why Al in Married... with Children hasn't just up and left his ungrateful life parasite of a wife and kids. Among Al's immortal quotes:
"Women. You can't live with them, you can't shoot them". "Women, can't live with 'em, can't herd 'em all into Canada" "Women. Can't live with 'em... The End."
Jerry and Elaine in Seinfeld, in that they are no longer interested in each other sexually but still hang out with each other because they don't have many other friends.

P!nk's song "Leave Me Alone (I'm Lonely)" is all about the bi-polar affections of a girl wanting some space, promising cuddling later.
The song "That's a Woman" is sung by Ryan Kelly and Paul Byrom of the group Celtic Thunder and is about a misogynist who finally falls for one of the women he so greatly disdains.
Celine Dion's "I Hate You Then I Love You." The title should be self-explanatory.
Senator John Dean's seminal dubstep/dubhop song, "Can't Live Without Em," a staple of the new genre. "Can't Live Without Em"

Amanda and Elyot in Private Lives. They fight both physically and verbally, to the point of having divorced, but as they find when they actually meet again after remarrying different people, they are perfect for each other.
Fire Emblem has several examples of this; Erk and Serra in Blazing Sword, Lalam and Percival in Sword of Seals, and to an extent Rennac and L'Arachel in The Sacred Stones. ( His single ending states that he tries to escape her service, but admittedly doesn't try very hard.)
In Final Fantasy VIII, Squall spends the first two discs of the game grimly resisting Rinoa's efforts to get him to open up to her. When she falls into a coma at the end of disc two, however, he realizes how much he doesn't want to lose her, and abruptly she becomes his main priority.
Not so abrupt if you unlock certain scenes or do certain events correctly (the "band concert" event being a big example; you have to get the music exactly right or Squall will just be annoyed with Rinoa the whole way.)
Also a long running plotline in Bittersweet Candy Bowl. Mike and Lucy spend most of their time agonizing over this fact.
In Sluggy Freelance Gwynn tends to flirt with this trope a lot in regards to the rest of the main characters.
So did Zoe to some extent. The boys drove her nuts, but when she moved back home, she found she missed them, and ended up getting a job consisting entirely of recounting their crazy antics over the radio.
Looking for Group looked like it was going for a joke like this after Cale'Anon had gotten into an argument with his girlfriend, but the trope is ultimately (and naturally) subverted because the man who almost invoked the trope is a wee little bit worse than the common chauvinist...
Vork: Women. Can't live with them — they will not go out with me.
Pinky and the Brain. Brain insults Pinky frequently and takes every opportunity possible to bop him with whatever solid object is convenient, but should Pinky wind up missing or genuinely hurt, Brain truly feels bad for his companion. In the Halloween episode, Pinky gives himself up to a malicious supernatural entity so that Brain can take over the world, and Brain gives it all up in order to get Pinky back.
On an episode of Animaniacs this is parodied when Yakko, Wakko and Dot tell their latest victim, who is begging them to leave, that he'll "be lonely when they're gone". Predictably, after they leave, the man bawls "I'm lonely!"
This was also done to the Warners in a different episode: they are followed around all day by an extremely dull man who continually tells a long, rambling story in a monotone voice. No matter where they run, they can't get away from him. Finally, at the end of the episode, he suddenly finishes his story and leaves. The three of them just sit in stunned silence for a few minutes, then declare "It's too quiet!" and go running after the man begging him to come back.
One of the later Sideshow Bob episodes of The Simpsons shows Bob realizing that he can't kill Bart. He's grown accustomed to his faaaaace...

The early Tom and Jerry short "The Lonesome Mouse" has Tom getting evicted from the house. Jerry is initially delighted, but comes to realize that he's bored stiff without his adversary, and schemes to get him back in Mammy Two Shoes' good graces.
Tom and Jerry are pretty much like this by default.
In KaBlam!, dispite being his friend, June seems to get a kick out of hurting or watching Henry get hurt. However, in an episode where he leaves the show, June finds herself crying over missing him.

Subverted in My Gym Partner's a Monkey. Principal Pixiefrog starts saying "Women! You can't live with 'em..." He pauses, and we expect him to say "You can't live without 'em," but then he says "That's all. You can't live with 'em."
