'''Basic Trope''': One character loves another and, upon being rejected, tries to kill them.
* '''Straight''': [[{{Yandere}} Bob]] loves Alice a great deal... so when she picks Charlie instead, he kills her for her "betrayal".
* '''Exaggerated''': Alice smiles at one of Charlie's jokes. Bob [[KillItWithFire burns]] [[DisproportionateRetribution her]] [[CruelAndUnusualDeath alive]].
* '''Downplayed''': Bob loves Alice a great deal... so when she picks Charlie instead, Bob spreads mean rumors about both Alice and Charlie, causing them to break up
* '''Justified''':
** [[WoobieDestroyerOfWorlds Bob has been betrayed by the people he cares about his entire life]], and after [[StalkerWithACrush he learns that]] Alice isn't interested in him, he [[DespairEventHorizon finally snaps]].
** Bob was [[InLoveWithLove in love with the idea of Alice]], and because the Alice does not line up with this idea he kills her so the idea can live on.
* '''Inverted''':
** Alice breaks up with Charlie to be with Bob, and Bob kills her for hurting Charlie.
** Bob is so heartbroken that Alice doesn't return his affections for him, he [[SpurnedIntoSuicide takes his own life]].
* '''Subverted''':
** When Alice picks Charlie, Bob declares that [[IWantMyBelovedToBeHappy her happiness is more important to him than his own]]...
** Bob is a StalkerWithACrush, but Alice finds that [[StalkingIsLove to be romantic]], and EverybodyLives.
** When Alice tells Bob she'd rather be with Charlie, Bob raises a gun to Alice before the camera [[DisturbedDoves cuts to a scene of a flock of birds flying coupled with a gun shot and a scream]]. However, it turns out [[DrivenToSuicide he turned the gun on himself]].
* '''Double Subverted''':
** ...Except [[ILied he was lying]] and slits Alice's throat in her sleep, but at least wanted her to die happy.
** ...Alternately, Bob is a MagnificentBastard and [[BatmanGambit the entire thing was a ploy to impress Alice with his apparent maturity]], and he patiently waits until a few weeks after the wedding, before quietly arranging for Charlie to have an "[[DiabolusExMachina accident]]" and [[DieForOurShip die]], before immediately going to comfort Alice in her loss, [[DangerouslyGenreSavvy knowing that the]] {{last g|irlWins}}uy wins.
** Except that Alice [[GenreSavvy realizes just how far Bob is willing to go]], and is so terrified of being killed that she plays along with it.
** Bob winds up shooting himself instead, and Alice [[DiedInYourArmsTonight rushes over and holds him as he dies]]. While she's caught off guard, however, he shoots ''her'' so that they can be TogetherInDeath.
* '''Parodied''': Bob attempts to off Alice and Charlie during their date, [[{{Slapstick}} in increasingly ridiculous ways that keep backfiring]].
* '''Zig Zagged''': Bob is a StalkerWithACrush who borders on {{Yandere}}. At first, Alice appears to be [[{{Squick}} Squicked]] out by this behavior, but then turns out to be a NightmareFetishist who finds it endearing. Except that she [[LikeYouWouldReallyDoIt doesn't take his threats seriously]]. After a drunken one-night stand with Charlie, she wakes up to find Bob standing over them with a [[KnifeNut butcher's knife]] and a SlasherSmile. Turns out he's understanding enough to let Alice live because she was drunk and wouldn't have cheated on him were she sober... [[InsaneTrollLogic but then]] [[LoveMakesYouCrazy he]] [[NoHoldsBarredBeatdown goes berserk]] on Charlie for "tempting/corrupting her". This firsthand evidence of Bob's psychosis disturbs Alice so deeply that he rejects him out of sheer terror, this time sending him [[UnstoppableRage completely over the edge]]...
* '''Averted''':
** Alice and Bob have a healthy relationship.
** Alice cheats on Bob, and he does nothing more drastic than break off the relationship.
* '''Enforced''': ???
* '''Lampshaded''': "Alice, I wouldn't date Bob if I were you. He's a little too possessive for his own good. And for yours."
* '''Invoked''':
--> '''Bob''': "If you don't [[PrecisionFStrike fucking]] love me Alice, I swear I'll kill you! No one deserves you in here but me!"
* '''Exploited''': ???
* '''Defied''': Bob is commiserating with his friend Dave about Alice and Charlie's new relationship when Dave suggests revenge. Bob is horrified at the DisproportionateRetribution.
* '''Discussed''': "Ever notice how Bob starts fingering that knife whenever Alice is chatting with some other guy?"
* '''Conversed''': ???
