This is when somebody tries to ruin someone else's romantic relationship or marriage.

There are various reasons someone might do this. One of the most common is that the saboteur is in love with one of the people in the relationship, and is willing to stoop pretty low to "correct" this situation. (In extreme cases, they may even try to Murder the Hypotenuse.) Alternatively, it could be that they just want Revenge for something, or that they want to free up one of the parties for a bit of gold digging, or that they're simply bitter that someone else is so happy and they're not. Sometimes, they may even be acting from a genuine, well-intentioned, and possibly even accurate belief that their friend has made a poor choice or should have chosen someone else.

The range of techniques available to a relationship saboteur is similarly varied. Lying is popular - you just need to make one half of the relationship look bad, such as by fabricating evidence of an affair or trying to make them flunk a Fidelity Test. It could be as simple as giving deliberately lousy relationship advice. If the relationship is fairly new, being a deliberate Moment Killer might be an option, and might prompt the saboteur to follow the targets on dates.

See also Break Up Demand for a different method of achieving the same goal. Contrast Shipper on Deck, where someone is trying to create a relationship rather than destroy one.

Examples of Relationship Sabotage include:


  • In one commercial, one teenage boy forces his younger brother upstairs so he can spend time with his girlfriend. The younger brother then uses the TV to show the girlfriend a slideshow of pictures that indicate he's cheating on her.


  • In the backstory of Saiunkoku Monogatari, Kou Reishin and his friend Houju were both interested in the same woman. Reishin sabotaged Houju's relationship with her by forging a letter from her to Houju saying she couldn't bear to be with a man so much more beautiful than herself. As a result, Houju started wearing masks all the time and calling himself "Kijin," meaning "weirdo," and Reishin married the girl.
  • Skuld in Ah! My Goddess, who takes her Big Sister Worship towards Belldandy a bit too far and won't stand for anyone, particularly lowly mortal Keiichi, getting too close to her. She frequently sets up booby traps (mostly involving Stuff Blowing Up) to prevent their relationship from progressing. It is hinted a few times, though, that she's acting out not because she's jealous of Keiichi for taking Belldandy's attention, but that she's jealous of Belldandy for getting Keiichi's love.
  • Makie from Futari Ecchi does that at every opportunity to the main character couple. I.e., she leaves false lipstick marks on Makoto's shirt or calls him in the middle of a date with his wife Yura.
  • Happens more than once in Marmalade Boy, with the most notorious perpetrators being Kei Tsuchiya (who grabs Miki's medallion/bracelet and gives it to Yuu saying she threw it away; Yuu is Genre Savvy enough to not buy it, but he and Miki still almost break up due to stress.) and Ginny Golding (who lies to Miki by telling her she was Yuu's "other woman" as a prank; this causes the already distraught Miki to break off her and Yuu's Long-Distance Relationship.)
  • Naruto, after finding out that Sakura doesn't care for him at all while he's disguised as Sasuke, is forced to retreat to the restroom because he drank spoiled milk in the morning. While on the toilet, he plans on returning to Sakura, still disguised as Sasuke and acting like a jerk in order to make her hate him. By the time he gets out, though, Sasuke has already escaped his bonds, and coldly told Sakura that he finds her annoying (although the way the scene is presented leads viewers to initially think that it was Naruto in disguise carrying out his plan).
  • Ranma ½: Ryoga, Shampoo, Ukyo, Kodachi, and other characters all try to sabatoge Ranma and Akane's engagement at some point or other.
    • Ranma and Akane team up in the manga to thwart the possibility of Hinako and Soun marrying.

Comic Books

  • At the end of Frank Miller's Daredevil, a grieving Matt Murdock had pressured his rather fragile girlfriend Heather Glenn into agreeing to marry him, which was literally driving her to drink. Believing that no good could come of this for anyone, Matt's partner Foggy and his ex the Black Widow created forged notes telling each partner that the other one wanted to break it off and never see them again. The immediate consequences were never shown, but a few years later Heather committed suicide.
  • Lana Lang attempted this occasionally when her jealousy of Clark and Lois' marriage got the best of her. In one instance she tried to convince Clark that Lois was a bad wife and left her panties in the Kents' bed in a fit of jealous anger when Clark refused to be swayed by her arguments.

Live Action TV

  • In the sixth season of House, House decides to try to break up Cuddy and Lucas after deciding that he might just be interested in the former.
  • In Sugar Rush (TV), the efforts of Sugar to sabotage the relationship between Saint and Kim rather indicate that she's not being honest about having no interest in the latter.
  • In The Big Bang Theory, Evil Wil Wheaton sabotages Leonard and Penny's relationship in order to win a bowling game!
  • On Gossip Girl, this is Blair's MO. And not just for own ex-boyfriends - she's perfectly happy to break up any new relationships that might make Serena unhappy too. Chuck, as well, loves to mess with any relationships that would a) stop Blair being with him or b) distract Nate from their friendship. And Jenny does this occasionally. And Vanessa - oh, screw it, let's just say Gossip Girl is built around this trope and leave it at that, okay?
  • On How I Met Your Mother Lily has done this to Ted six times, each time because she thinks the girl Ted's dating is a bad fit for their group of friends. Methods range from planting a woman's earring in Ted's bed so his girlfriend thinks he's cheating on her, to planting a Creed CD in the girlfriend's apartment so that Ted becomes disgusted with her, to dressing up in the girlfriend's Darth Vader costume, pretending to be her, and telling Ted they should see other people.
    • Later on, Lily is called upon to break Barney and Robin up, but a sudden bout of Complexity Addiction almost does her in.
  • Happened all the time on Rome.
  • This is pretty much Diana Fowley's job during season six and seven of The X-Files. She's working for the Syndicate to lure Mulder, but whether her true aim in breaking up Mulder and Scully is professional or personal (she's Mulder's ex-partner and may or may not be his ex-wife) is up to interpretation. She plays off Mulder's previous trust in her, and almost succeeds in breaking them up. To the delight of many a shipper, she is killed off in the early parts of season seven.
  • The season 4 finale of ICarly had a revelation that Sam likes Freddie. It's quite possible that her actions in iSaved Your Life, where she completely fucked up Carly and Freddie's newly formed relationship by planting seeds of doubt in Freddie's mind was a subconscious desire to sabotage the relationship to keep Freddie away from Carly.
  • In pretty much any episode of Glee in which Finn Hudson is dating somebody not named Rachel Berry, you'll find Rachel trying some form of this, by means including: staging singing lessons that are intended to turn into something a lot less innocent; dramatic changes of appearance (fortunately Kurt was onto her and ensured it didn't work); informing Finn that his girlfriend is pregnant by another boy; duetting with other boys (particularly if it's the boy who got his first girlfriend pregnant) to make Finn jealous; and encouraging him to distrust his girlfriend and spy on the boy a blind item in the school newspaper implies she's cheating with in company with, you guessed it, Rachel Berry. Every single one of these backfires on her in some way. You'd think she'd have caught on by now, but no such luck...


  • In My Best Friend's Wedding, Julianne tries to derail the upcoming marriage of a guy who had promised to marry her if they were both still single at a certain age. It fails, epically.
  • Pretty much the entire plot of the film Saving Silverman.
  • Both Balraj's sister Kiran and Darcy's mother try very hard to keep Jaya and Lalita very far away from Balraj and Darcy in Bride and Prejudice.
  • Sherlock Holmes went out of his way to try to get Dr. Watson to not get engaged to Mary since he wanted to keep him for himself. He insulted Mary with a deduction and he paid a fortune teller to plant seeds of doubt into Watson's head. He eventually did give his consent.
  • In Plan B, Bruno's "Plan B" to make his ex-girlfriend Laura and her new boyfriend Pablo break up is to seduce Pablo and drive him away from her. It works, but by then it's not Laura he wants to be with.


  • In Pride and Prejudice, Darcy breaks up Jane and Bingley's relationship because he thinks Jane is just stringing his friend along, due to her lack of showing affection. This is the main thing that leads Elisabeth, Jane's sister, to think that Darcy is an a-hole. The reveal is what leads her to realize that she loves him.
  • Dr. Sloper in Washington Square goes out of his way to ruin his daughter Catherine and Morris's relationship, culminating in taking her on a trip to Europe for a full year to test the strength of their affection. His reasoning is that he is convinced that Morris is nothing more than a Gold Digger after his family's fortune. He turns out to be right.
  • April Pierce half-successfully pulls this in Catherine Anderson's Strawberry Hill, lying to the heroine Vickie about having slept with her fiancé Slade. While Vickie does believe her and break it off with Slade, April still fails to land Slade for herself. Worse for her, Slade is pissed when he finds out the truth and gives her hell, blackmailing her into telling Vickie the truth.


Video Games

  • In Tokimeki Memorial 2, Knight Templar Big Brother Kaoru "Sou-Banchou" Ichimonji will constantly try to do this in Akane's storyline. Resolved to prevent any boy to hurt her little sister's feelings, and also fearing to lose her (who's his sole family) if she ever hooks with a guy, he will sic at the MC his underlings, then will fight him in person, will barge in the scene if he feels you're too close from her, and in Memories Ringing On, will even go as far as trying to sabotage the wedding ceremony preparations with her by threatening the assembly hall's clerk of obstruction of business! Said sister is not very pleased by her brother's antics, and constantly resolves them with a Megaton Punch.
    • Kaoru does have somewhat of a point, as his sister was badly hurt in the past by her First Love: a boy who moved away and thus abandoned her when they were little. It really doesn't help that the MC is said boy, though to be fair it's not like he could do a lot about it.

Web Comics

  • In General Protection Fault, Trudy steals Ki's stuffed animal "Mr. Pookel" and leaves it where Nick will find it so that he'll learn her screen name. He's upset with her for not telling him in order to test his loyalty, but utlimately forgives her.

Western Animation

  • The Simpsons once had Bart try to break up the relationship of his Precocious Crush (with the added motivation that the person she was going out with had bullied him).
    • In an earlier episode, when his best friend Milhouse started 'dating' the new girl at school, he tipped off the girl's Overprotective Dad so Milhouse would hang out with him again. He ended up regretting it.
    • In another episode, Milhouse's parents (who several seasons back had a nasty Toilet Seat Divorce) are getting back together. Which seems great at first, except that Milhouse starts to feel that they're ignoring him. He complains about this to Bart, and Bart sees a Teen Drama on TV wherein a girl angrily dumps her boyfriend because she found another girl's bra in his room. Bart steals one of Marge's bras and leaves it in the Van Houtens' bedroom. But because the bra had Marge's name sewn into it, it poses a threat to Homer and Marge's marriage as well. Homer and Marge reconcile over the fact that it was a big misunderstanding.
    • Marge's sisters Patty and Selma are constantly trying to destroy Marge's marriage to Homer, whom they can't stand. They'll even go so far as to kidnap him the day of his and Marge's fourth wedding, or take advantage of Marge's memory loss to hook her up with another guy! Luckily, their plans always fail to the strength of both the couple's love and the show's status quo.
    • Moe, who's in love with Marge, has tried to break her and Homer up as well. He fails because he's Moe.
  • King of the Hill: Peggy sabotages Lucky & Luann's relationship.
  • Helga always fails at this in Hey Arnold.
