i've fancied my best friend's boyfriend for ages, before they went out and all the way through their relationship (4 months).
recently their relationship has been really rough and they haven't really been speaking. he's been flirting with me quite a lot and asking me to see him on his own, and stuff.
she cheated on him last week, just a kiss but it sounded like quite a major pulling session. she doesn't want to tell him about it UNTIL she knows what's going to happen with the guy she cheated on him with, i.e. if he wants to go out with her, she will break up with her boyfriend, but if he doesn't, she won't tell her boyfriend... personally i think this is wrong but i haven't said.
her boyfriend then called me yesterday to ask me what i thought about him breaking up with her. when i asked him why he went silent and wouldn't tell me why he wanted to break up. but he talked about the guy she cheated with during the conversation normally, so i don't think he has found out.
basically, i don't know what to say to him when he asks me whether he should break up with her. i don't want to encourage him because it would be obvious that i like him, and i can't tell him about her cheating on him. but i don't want him to stay with her, because she's using him! what should i say to him?
thanks for any replies.
