There are a lot of tropes for platonic relationships between men and women.

* AmicableExes: They were in a relationship, but despite the breakup are still on good terms.
* BelligerentSexualTension: When JustFriends crosses over into willful stupidity.
* IDontWantToRuinOurFriendship: They're JustFriends, and worried about losing that if they try to become something more.
* FanPreferredCouple: It won't happen even though some people are rooting for it.
* JustFriends: [[{{Pun}} Denial's not a river in Egypt.]] They are totally JustFriends. [[ShipTease Until]] [[RelationshipUpgrade they aren't.]]
* LikeBrotherAndSister: It won't happen because it would be too squicky for them.
* PlatonicLifePartners: It just won't happen. Ever.
* RomanticRunnerUp: The unlucky third wheel of a LoveTriangle.
* SheIsNotMyGirlfriend: Yes, she is. Or, at least, she will be.
* IWantMyBelovedToBeHappy: When someone who is in love with another decides it's best if they be with one another.
* FriendsWithBenefits: The duo is friendly with one another and has some good sex, but they are not currently an OfficialCouple.

'''This trope is for when it happens once and won't happen ''ever again.'''''

Two people date for a while, realize they're Better As Friends, and use that as their excuse when asked. Sometimes this leads to a {{UST}} plotline, but not always.

Note that this isn't just people who stay on good terms after a break-up, but who really do remain good friends to the point where the plot uses them as an OddCouple at times.

!!Examples:

[[folder:{{Anime}} and {{Manga}}]]
* Michiru and Aso from ''Manga/ZombieLoan'', after one date. He kept [[AffectionateGestureToTheHead affectionately rubbing her head]], like how a parent would do to a child, and she even referred to him as a "father" once.
* In ''Anime/{{Doraemon}}'' the protagonist's love rival [[TheAce Dekisugi]] describes himself as this toward Shizuka when the story explores [[TimeSkip the main characters' future]], which partly explains why [[OfficialCouple she and Nobita become a couple]] despite the episode initially suggested otherwise.
[[/folder]]

[[folder:Comic Books]]
* In Creator/PhilFoglio's ''ComicBook/AngelAndTheApe'' miniseries, sentient gorilla Sam Simeon is turned human by a superpowerful cosmic thingy (long story) and shares a long kiss with his partner Angel O'Day...then backs off; he feels that their relationship as friends is too important to mess with. She agrees, a touch wistfully.
* Creator/JoeQuesada is [[OneMoreDay trying to set up]] [[{{Spider-Man}} Peter Parker and Mary Jane Watson]] as this, after they spent multiple decades as the OfficialCouple and HappilyMarried. Needless to say, fans aren't buying it (both literally ''and'' figuratively).
[[/folder]]

[[folder:Film]]
* The conclusion of ''Film/AnnieHall''.
* Subverted in ''Film/WhenHarryMetSally''.
* In ''Film/BadlyDrawnRoy'', [[RogerRabbitEffect Roy]] and his girlfriend Ruth eventually break up since they [[NonhumansLackAttributes couldn't take the relationship to the next level]], but they remained friends.
* This is what Shaggy and Velma decide after they kiss at the end of ''Film/ScoobyDooCurseOfTheLakeMonster''.
[[/folder]]


[[folder:Literature]]
* Alanna and Jonathan in TamoraPierce's ''Literature/SongOfTheLioness'' quartet, due to intentional ShipSinking by the author after she realized the relationship didn't work. Alanna becomes Jonathan's King's Champion and they both marry other people.
* Zeb and Maggie from Creator/RobertAHeinlein's ''Literature/Revolt in 2100''. The hero sort of wants to pursue a relationship with her but doesn't want to get in the way, at which point he's told laughingly that by now they're great friends but that their personalities are far too aggressive to ever be stable together.
* Jo feels this way about Laurie in ''Literature/LittleWomen''. She says that the two of them are too much alike ever to pursue a romantic relationship successfully. Laurie disagrees until he marries Amy, after which he tells Jo he's happy to love her as his sister. As the LikeBrotherAndSister analogy was used to describe ''both'' his relationships with Jo ''and'' Amy, this has done nothing to convince shippers from the 1860s onwards that they are ''not'' better as friends.
* The WhereAreTheyNowEpilogue to Creator/DaveBarry's novel ''Big Trouble'' has this as the fate of Jenny and Matt, after [[spoiler:her mother and his father getting married]] makes them feel a bit LikeBrotherAndSister.
* Happens several times in Creator/MercedesLackey's ''Literature/HeraldsOfValdemar'' series, most notably to Kris and Talia of the "Queen's Own" trilogy and Daren and Kerowyn of "By the Sword." They ''all'' go on to relationships with other people, and very happily so, without losing their friendships. [[spoiler:Except for Kris, who gets killed.]]
** Subverted with Talia and Skif, who fall comfortably into this trope without ever getting into an actual physical relationship (they ''try'', but various bits of serendipity get in the way). Amusingly, their peers assume the trope played out straight.
* One of Gerald Morris's Arthurian novels, ''The Ballad of Sir Dinadan'', has the hero end the book by going to find his female companion, who is currently training to be a nun. He proposes to her. When the Mother Superior comes out and realizes what has happened, she prepares to go pack her pupil's bags.
--> '''Dinadan''': Yes, I asked her. And she's made me the happiest man on earth.
--> '''Mother Priscilla:''' Ah, she has, has she?
--> '''Brangienne:''' Yes, I have. I turned him down.
* What Dex and Emma initially decided on in ''Literature/OneDay''.
* In ''Literature/KeepingYouASecret'', Holland realizes two things: that she's a lesbian, and that starting a sexual relationship with her childhood friend Seth had been a big mistake that ruined their friendship. She tries to tell Seth this when she breaks up with him, but he doesn't understand and is furious.
* Though only mentioned as backstory, Nathan and Cynthia are this in ''Literature/TheMemoryWars'', having dated briefly in college, but [[AmicableExes remained close friends]].
* ''Literature/VampireAcademy'':
** How Rose thinks of Mason. In ''Frostbite'', she eventually agrees to date him (in an attempt to get over Dimitri) but she's never truly attracted to him.
** Ultimately, Rose and Adrian too.
[[/folder]]

[[folder:Live Action TV]]
* Jerry {{Seinfeld}} and Elaine. One {{UST}} episode that [[NegativeContinuity doesn't actually seem to be canon]]. It's PlayedForLaughs in the last episode as they seem on the edge of a DyingDeclarationOfLove during a plane crash, only to quickly backpedal once they survive (Elaine claims she was about to say "I've always loved U...nited Airlines").
* Willow and Xander in ''[[Series/BuffyTheVampireSlayer Buffy]]'', whose UnluckyChildhoodFriend and ObliviousToLove statuses only give way to romance when they're both in other relationships. Willow chooses her relationship with Oz (and then, after they break up, [[NoBisexuals discovers she's a lesbian]]) and she and Xander remain best friends.
** Also Cordelia and Wesley, whose smoldering {{UST}} when they met in ''Series/BuffyTheVampireSlayer'' came to a head with their first kiss -- which quickly became their very [[AwkwardKiss awkward and physically uncomfortable]] ''last'' kiss. Their friendship continued to grow in ''Series/{{Angel}}'', but they aren't above playfully making fun of each other over which one's the worse kisser when recounting the story for others.
* On ''Series/CriminalMinds'', JJ and Reid go on one date . . . and end up close friends, and nothing more.
* Harry and Christine in ''Series/NightCourt'' (lampshaded later where, after Christine turns down an invitation from Harry, Harry responds giddily "Isn't it great? We can say 'no' again!")
* Frasier Crane and Roz Doyle in ''Series/{{Frasier}}''.
--> '''Roz:''' You've always been just like a brother to me. Which is weird, I know, because we slept together and...
* Ted and Robin from ''Series/HowIMetYourMother''. [[spoiler:Although they hooked up in Slapsgiving and Benefits.]]
* Nate and Blair on ''Series/GossipGirl''.
* Margaret and Rain in ''Series/NaturallySadie''.
* On ''Series/{{Bones}}'' we have Booth and Cam. Dated before the show started, broke up, hooked up briefly after she joined the cast, broke up again, and seem determined not to mention it ever again. Since he's [[OfficialCouple obviously]] [[EveryoneCanSeeIt in love]] [[BelligerentSexualTension with Brennan]], [[FanPreferredCouple the fans]] are mostly willing to accept this.
* [[spoiler: George and Izzie]] from ''Series/GreysAnatomy''.
* ''Series/BoyMeetsWorld'' has Jack and Rachel becoming this after briefly dating each other.
* Bernard and Fran on ''Series/BlackBooks''.
-->'''Bernard:''' Well, I did [[[WhatDidIDoLastNight remember what happened]]] for a while. I think so. Then she made me block it out. That's it - she remembers, and I'm not allowed to.
* ''Series/ICarly'' had Sam and Freddie date for 5 episodes. It was pretty horrible, constant fighting, hurting each other and so on. In the 5th episode they mutually break up because they were forcing a platonic friendship into something more. Freddie says he loves Sam, but it's clearly as a friend.
* ''Series/{{ER}}'' has Doctor Kovac and Nurse Sam after they dated and decided to remain friends. Likewise with Abby and Carter. Even earlier, with Elizabeth and Peter, when she finally realizes that their personalities are far too different and that he'll never get over his discomfort with their interracial relationship.
* ''Series/TheWonderYears'' ends like this for [[spoiler:Kevin and Winnie]].
-->''[[spoiler: Still we never forgot our promise. We wrote to each other once a week for the next eight years. I was there to meet her when she came home...with my wife, and my first son, eight months old.]]''
* ''NoahsArc'': Ricky and Noah, despite Ricky admitting he is deeply in love with Noah.
* On ''Series/{{Smallville}}'', Chloe lusted after Clark Kent in the earlier seasons[[note]]she is most obvious about it around season one and two, but it actually carried all the way to season six, which caused a lot of problems with her current LoveInterest[[/note]], and it initially looked like her status was going to be as the RomanticRunnerUp and UnluckyChildhoodFriend, but ultimately she got over her infatuation and moved on with her life; and she and Clark ultimately decided that they were Better as Friends and developed a LikeBrotherAndSister relationship.
* ''Series/TheAdventuresOfPeteAndPete'' ''tried'' to pull this with Big Pete and Ellen, though the show's reluctance to bother with continuity meant it didn't stick and Big Pete was back to pining for Ellen a mere seven episodes later.
* In ''Series/{{Community}}'', Jeff Winger and Britta Perry have zigzagged between just good friends and FriendsWithBenefits. It was revealed in the latter half of season two that they'd been hooking up on occasion, but since then it appears they've just settled into a purely platonic friends dynamic.
** Between season three and four, Troy and Britta start a relationship, but near the end of the season, they decide to going back to just being friends.
* This is the case with Matt Donovan and Elena Gilbert of ''Series/TheVampireDiaries''. In both the TV show and the book series, Elena and Matt dated before the series beginning, with Elena (in the show) describing it as those friends who've known each other forever deciding to give a relationship a shot. It's revealed later in the series that the death of Elena's parents was the final nail in the coffin of her romantic relationship with him, and while he still has feelings for her through most of the series, they remain good friends.
** Also seems to be the case with Bonnie and Jeremy--they still seem to care about each other, but there has been no indication that they intend to resume their relationship.
** Ditto Caroline and Matt. They broke up after Matt realized Caroline was a vampire, and while he eventually got over it, she moved on to Tyler.
* In ''Series/ClarissaExplainsItAll'', Clarissa and Sam try dating in one episode, but they eventually decide on this.
* ''Series/TheLWord''. PlayedForLaughs when Jenny takes home another girl after her first lesbian crush, only to find that their awkward fumblings lack chemistry. At the end the two girls blurt out simultaneously, "Let's just be friends."
* In ''Series/MyMadFatDiary'', Rae and Archie quickly come to this conclusion after Archie discovers that he's actually gay.
** Finn and Chloe [[spoiler:seem to have a similar fate after Rae and Chloe reconcile.]]
* ''Series/{{Friends}}'': Rachel and Joey.
* After a (very) brief marriage [[Series/BabylonFive John Sheridan]] and Elizabeth Locksley realize they have made a horrible mistake and that this trope definitely applies to their relationship. Despite years of separation and being on opposite sides in the war they still have implicit trust in each other and an excellent working relationship. They prefer not to tell people they are exes though, they may draw the wrong conclusions.

[[folder:Music]]

* The point of [[Music/NoDoubt Gwen Stefani]]'s "Cool":
-->''And after all the obstacles''
-->''It's good to see you now with someone else''
-->''And it's such a miracle that''
-->''You and me are still good friends''
-->''After all that we've been through''
-->''I know we're cool''
[[/folder]]

[[folder:Web Comics]]
* [[http://outthere.keenspot.com/d/20090203.html Miriam and Clayton]] in ''Webcomic/OutThere''. Although Miriam being Miriam, [[http://outthere.keenspot.com/d/20100904.html one never knows for sure about the "never happening again" part]]. Also, [[http://outthere.keenspot.com/d/20090701.html Miriam and Rod]].
* Bowler and Creepknight in ''Webcomic/VoodooWalrus''. Its been eluded to that long ago there was something more romantic about there relationship. But that's most definitely not the case now.
** Honestly they seem to have more of sibling relationship than anything else.
* ''Webcomic/{{Homestuck}}'': Meulin and Kurloz dated for a while and were pretty happy together, but after a disturbing and painful incident for the both of them, they broke up. However, they are clearly still very good friends. Unless you think Kurloz's MindControl is a bit more extensive than what we've seen so far, anyway.
* Subverted in ''Webcomic/ElGoonishShive''. Justin and Melissa were childhood friends who decide to have a RelationshipUpgrade... but it's this very thing that makes Justin realize he's [[IncompatibleOrientation gay]]. They decide to remain friends... but here's where things get sour. [[spoiler: Melissa was so distraught by this revelation that she confides in her sister... who is a ''huge'' gossip. Soon, everyone at their school knows, and Justin's parents even learn it by overhearing it at the grocery store. It also leads to lots of bullying aimed at poor Justin, who came very close to committing suicide over the whole ordeal. Justin blames Melissa for all this, which leads to the end of their friendship.]]
** A happier example comes from Elliot and Sarah, who start dating early in the comic. Much later, they both, around the same time but independently, come to the conclusion that the relationship isn't really working out, and (very amicably) break up, going back to their old ChildhoodFriend dynamic.
* Ally and Alan from ''Webcomic/{{Sunstone}}'' had an incredibly political relationship back in collage, which is in extreme contrast to how laid back their strong friendship is now. This was due to their sexual desires not being compatible.
* ''Webcomic/GirlsWithSlingshots'': [[spoiler: Hazel and Zach]] in the webcomic's final strip.
[[/folder]]

[[folder:Web Original]]
* Bree and Daniel from ''WebVideo/{{lonelygirl15}}'', after much arguing, much WillTheyOrWontThey, and a fair amount of {{Wangst}}.
* This is the theme in [[Music/{{Vocaloid}} Luka Megurine's]] song "Just be friends". The man in the song (from whose viewpoint it's sung) is still in love with the girl and wishes he could get back to the past to begin again, but also recognizes that the relationship ''now'' is going nowhere and prefers to split and save whatever remains of friendship can be salvaged.
* Thalia and Hephaestus in ''ThaliasMusings''. Hardly anyone remembers that they used to date. Hephaestus is in love with Aphrodite in spite of her constant cuckolding, and Thalia is [[SuspiciouslySpecificDenial totally not in love with Apollo]].
[[/folder]]

[[folder:Western Animation]]
* Trixie and Spud from ''AmericanDragonJakeLong''.
* This is one-sided in ''WesternAnimation/DannyPhantom'' when [[DatingCatwoman Valerie]] gives Danny the ItsNotYouItsMyEnemies speech and declares they should just be friends. Danny is visibly upset for a time, but gets over it by [[FirstGirlWins Season Three]].
* In ''ElTigre'', despite the romantic persistence of Manny's father Rodolfo, his ex-wife Maria keeps insisting that they should remain JustFriends.
** Interestingly enough, this is PlayedWith. She still loves him, but she can't bear the sight of him getting hurt from being a hero. WordOfGod states that they remarry once he retires.
* Nelson Muntz and Lisa Simpson in ''WesternAnimation/TheSimpsons''.
* [[spoiler:Jen and Alex]] from MTV's ''{{Downtown}}'' skirt very close to sleeping together in one episode, but decide that it makes more sense for them to remain friends than romantic partners.
* In ''WesternAnimation/CodeLyoko'' Yumi and Ulrich try this, but it is clear to both their friends and the viewers that it is only causing more tension from their {{UST}}.
* In ''WesternAnimation/TheLegendOfKorra'', Korra and Asami each dated Mako at some point. [[spoiler: As of the GrandFinale, the ladies [[AmicableExes count Mako as a good friend]] and are [[BiTheWay dating each other]].]]
[[/folder]]

[[folder:Real Life]]
* Lou and Peter Berryman, who met in college, started performing and writing wacky songs together, got married, got divorced, married other people, all the while (and still) writing and performing together.
* Creator/BenStiller and Creator/JaneaneGarofalo were a couple for a few years in the mid-Nineties, but continued to work together after they broke up. They even [[http://www.amazon.com/Feel-This-Book-Self-Empowerment-Satisfaction/dp/0345412931 wrote a book about it,]] as a parody of celebrity self-help books.
* The french philosophers Jean-Paul Sartre and Simone de Beauvoir met in their early 20s and became a couple. Though de Beauvoir declined Sartre's offer to get married, they never moved in together, and both had all kinds of other lovers, they stayed together for the next 50 years until their deaths and are even buried together. Better as friends, though friends with benefits.
* This is the main reason Hillary Duff and Mike Cormie have separated.
