you should tell him that your best friend has been there for you for everything and that you have to stand by her. if he can't accept that, then he's not a good boyfriend.
Move on.
if your best friend is going out with your ex-boyfriend then thats okay for them but if your best friends boyfriend says he doesnt like you anymore then he may not because you can always tell weather someone likes you when they call you names. if your best friends boyfriend does that then he odviously likes you
your friends boyfriend will breakup with your friend, and your friend will get mad at you.
If an old friend contacts you after months of not speaking and inquires about your boyfriend, they may have information about him. They may also like the guy.
Then what's your problem?
With friends like you your friend doesn't need anymore enemies. You have betrayed your friend and that bond of trust is broken and she will find out. You made the choice and could have said no.
Well think of it this way: Who is more important to you? Your best friend or your boyfriend's friends?
Well this is simple all you have to do is do something that he likes that your friend doesnt like doing with him if that doesnt work tell him in person how you feel when they get into an argruement
You have to move on and look for other friends.
just dont be her/his friend
Just be friends with him because if you try to get him to go back out with you then he might not even want to be your friend anymore.
Why did she have an affair with your boyfriend? This was a two-way street, and neither of them are your 'friends'. Friends don't do this to each other. Oviously your botfriend is a jerk who doesnt desrve to have someone like you! Just ignore him, and your supposed "best friend" is not a true one!
