you're not dating, and he's not an ex so thats fair game.
Sit her down %26amp; tell her once more how you feel about him....%26amp; tell him how you feel bout him..if sittin her down don't work then get even with her...or find someone better if he knows how you feel %26amp; is doin that then you deserve way better than some jerk whos gonna do that to you...and a friend that won't treat you that way..
