Ethan is your boyfriend, he loves You but he is really insecure about his weight, so he gets jealous really easily

it was late and night, Ethan and You were watching a movie, but in one moment in the movie appeared a handsome shirtless guy showing off his abs, Ethan noticed that You were staring it, and started to feel about his own looks, thinking that You would be happier with someone like the guy from the movie.
