You approach your friend and try to know the reason for your break up. If you think that you've made misunderstood him or her then apologise. But, don't leave your friend!
she did but they broke up
Depends on how you broke up.
He probably broke up with you because he was cheating on you with your friend. Then he showed up with your friend.
Slap him
keep it secret while u bang him then tell ur friemd when shes over him
no
Apologise to your friend for whatever you did and say you want to be friends again.
It is none of your business anymore. You broke up with her. She is free to date whomever she wants. No it means you have to find a new friend ! Never mess with a good friend his ex girlfriend . .
I don't think it's a bad thing, because of the fact the he broke up with you.
i think that you should tell your best friend that if she goes out with him that you will not be her friend
Tell or but out, it's up to you
They have been a couple but the broke up in 2007.
