One of the aspects of characters and their interactions that I struggle the most with writing, and that I see other writers struggling with, is the progression of sexual and romantic feelings between two characters. I see a lot of people trying to write it the way it is in movies, and that just doesn’t come across as believable in writing, the whole ‘they’re arguing but slowly moving closer together without noticing’ thing and, in first person, the “wait, what? I did NOT just think _____ is attractive, I hate him!” Emotions are so complex and subtle that it’s hard to describe or show them without being too obnoxious, or, well, TOO subtle. This is affecting a few of the characters I’m writing right now, but one pair more so than the rest. If I have two characters with a difficult relationship -half friendship, half resent, half completely confused- an aspect of which is sometimes-belligerent-but-always-unresolved sexual tension, how do I make those scenes between the two of them believable? How do you write the thoughts and feelings of a character who is slowly falling in love with someone and even more slowly realizing it?
