The only thing you can do is just move on if he cheated on you with your best friend. Don't be mad at her, it's not her fault. It is his fault he was not a true boyfriend after all.
ask your best friend if he likes him and if she doesnt than wait for him to get over it and he'll realize he likes you
If he is moving it is best to just leave things.
It's a choice that you're going to have to make.Either you can let your friend have him or you can forget about the guy and still be friends with your best friend.
If he likes your best friend and if you find she likes him as well the best thing you can do is nothing as she is your best friend and as to not cause any problems. Boys are not worth arguing over and you can keep friends longer than a boyfriend.
Nothing should come betwenn friendship. You need to talk to him/her and sort out what is going on. A crush is nothing to fight over.
Well really theres not much you can do but, warn your friend and talk things over with her. Just be there for her.
Solution: There really is no answer. That's how it goes, don't make your life a drama over this girl.
Talk it over if you want to stay friends.
if ur over it then good 4 u but u cant force a relatoinship
Answer is...you don't. You forget him because you are better than that and you should move on to someone else. He likes your best friend, get over it. And if she is really your bestfriend, she wouldn't go near him on that level.
never date your friends x's or current bf's. get over him, if you don't your not a loyal friend.
Show her that you have a backbone and get into a fight w the guy she's falling over.
