I would tell him that I understood, no one wants to be stuck with me and my god-damned moodiness, and then walk away, feeling depressed, because my boyfriend is also my best friend. One of the only Marafiki I have left.
Would wewe actually believe that most of women who would advise a girl to dump her cheating boyfriend would forgive their own cheating boyfriends and take them back? Just a (not-so) fun fact I'd thought I share.
Depends on who he cheated on me with. If it was someone I know, then I'd be irritated as hell. But if I didn't know the girl and it was only like a one-night-stand type of thing, I wouldn't care as much. I'd probably just roll my eyes.
