You don't. He's a loser and so is she.
I am madly in love with my best friend.
talk to her she will understand if she is your friend
Have her back in case she has a problem.
ignore her or tell her to back off
They both are bad. If your best friend cheats on you with your boyfriend, she is a NOT a loyal friend. And if your boyfriend cheats on you, DUMP HIM.
Boyfriend or best friend. But its usually used for best friend
Unfortunately there is not much you can do to get your boyfriend to break up with your best friend and come back to you as he has made his choice. Time may be the healer and he may realize he does love you, but there is always that risk he will either stay with your best friend or possibly break up with her and meet another girl.
if your best friend is a girl she may not be ready for a boyfriend if your friend is a boy then he isn't into boys.
that is serious, first you should tell your best friend who might think of a way and you might want to hit him back
Your boyfriend has a tongue in his head and he should be the one to tell your best friend to back off and you shouldn't have to say anything. Best friends do not try to kiss their other best friend's boyfriends. Tell her to back off or you will end your relationship with her. The word 'annoy' means to irk someone (they get angry or frustrated) and you should be angry more than annoyed. What your best friend is doing is out of line and your boyfriend needs a spine to learn to say the word 'back off' to her.
then she should leave her boyfriend and do something about the love she has for her best friend..
you should try telling them how you feel or go over to your ex boyfriend and ask him if he likes your best friend THEN you might want to tell them how you feel depending on the answer.
