You don't
If you still have feelings for her you to should get back together.
MAYBE YOU SHOULD IGNORE..
well if she likes you back then go get her! you are none of your ex girfrends business anymore
It depends on if your ex still likes you and if her friend is willing to help. If she is, then ask her to talk you ex into giving you a second chance.
If he's just a friend to you now, then you don't want him back.
if your ex likes your friend then you shouldn't really care about who she dates after that.
Rape them
ask your ex if they care..if they do, decide which person you like more..
think it just might be as a friend
The 'friend' obviously likes your ex and is jelous that you had a chance with that person who is now your ex and the 'friend' never had a chance. ignore that 'friend'.
not worry about it. its ur ex
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.
