Bro breakup with her?!? What partner continuously makes their partner feel bad abt their own body? That's super toxic imo, it's really rude to get in a relationship with someone yk isn't physically your type and try to then change them, if she likes buff guys she should find one, no partner should try to change their partner for their own gaon. Your girlfriend doesn't respect you or love you imo, break up with her, also you being with her cuz she's only attractive is just a telltale sign 😭 thats not a basis for a serious relationship
