You, my friend, have One-itus and she senses it. Play hard to get and not only give her the space she wants but blow her off the first time she initiates wanting to hang out with you. Trust Dr. Plan9 on this one...I know you most likely wont take my advise because you sound whipped but if you do you will get her back interested. If you continue to chase her and tell her how much she means to you and how much you like her, you will only make her run furthar and faster away from you.
Good luck
