What happens when someone involved in artistic or other creative endeavors enters into a relationship with a person only for his work to seemingly go downhill as a result? That's the question raised by the Love Makes You Uncreative trope.
In stories involving this trope, the artist in question may be in an extremely happy relationship but his significant other functions as the opposite of The Muse (i.e., an anti-muse). In some cases, there may be nothing wrong with this person—in fact she may be perfectly charming and likeable—except for the fact the artist's relationship with her has somehow caused him to start producing inferior work or no work at all. In other instances, if the artist character is a musician in a band or part of some other type of creative team and his object of love causes strain with the other members and alienates fans, there can be overlap with the Yoko Oh No trope. There also can be overlap with the Dungeonmaster's Girlfriend trope if the artist begins involving and displaying overt favoritism toward the significant other in his projects—often to their detriment. This situation is made even worse if the other person is an untalented Golddigger who's latching on to the artist for the purposes of gaining fame and/or money.
Related to True Art Is Angsty: an unloved, lonely and depressed artist is more likely to create "true" or "compelling" art than one in a happy relationship. Creator Recovery would be a supertrope. Compare Love Makes You Dumb. Contrast Creator Breakdown and Creator Couple which, when combined with this trope, can lead to a Couple Bomb.
Love Makes You Uncreative is a trope found in both fiction and Real Life. However, in the case of the latter, the decline in someone's work after his or her hook-up with someone unpopular with the Fandom is often subjective. Thus, this trope is limited to In-Universe Examples Only.

Agatha: What?! How- I mean- Why would you say that?
Gil: Listen to yourself. You're a strong Spark, but you're holding it back. You're so afraid of hurting him, you've gone all sloppy and helpless.
- In Ménage à 3, when Zii finally gets into a relationship with DiDi, she starts being late for and careless about band rehearsals.

One careless conversation later, Zii has no band.
- Legorobot, an MS Paint webcomic infamous for its Black Comedy, Crossing the Line Twice surrealist humor, and Memetic Mutation had a page where the author gushes over his girlfriend, causing him to evolves into a Bulbasaur.
