Maybe. It depends if she is still in love with him.
if he was your ex you should be over him. If your not over him you should tell your friend or try to get him back.
If you still have feelings for her you to should get back together.
MAYBE YOU SHOULD IGNORE..
just tell your best friend that you really like him and see what she says about it.
You date her best friend
do theyre best friend of course!
Ask them for it.
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.
Give them a gift.
probably because your ex wants to get back with you or the best friend wants to get with you... The best friend fancies you, hon.
Chances are, he/she is.
not worry about it. its ur ex
