Do you think it's over?

Get real man! Shes feeding off all of this attention and using you in the process. Don't play her games and get on with your life. You know if you give other girls the impression that you are stuck on just this one girl, then the other girls won't even approach you because they don't want to be rejected anymore than you do. Get out there and have lot's of fun playing the singles scene. You'll be married with children soon enough, so raise some hell during your single years. Good Luck!
