If she still hasnt changed her mind you need to move on. Find someone else, sometimes that causes the ex to get jealous and feel a way about it. She'll probably wonder "why isnt he chasing my ass anymore?I was loving all the attention"...and then you can say "To the left to the left"...lol...Im just kidding...plain and simple MOVE ON she aint the only chick in the bunch. There are better,sexier girls out there for you.Obviously it wasnt meant to be. Let it go. Besides, the more you be a pest the more she dislikes you around her.
