Oh shit... This can't be good

So heres my problem. I can't seem to get her out of my head. All i seem to do is think about her. Can we say obsessing a much? I have had two dates and they where great. Then she canceled our third cause she was/is sick. But all i can do is think about her. When i wake up my first thought about her. When i fall asleep she's what i think about, and when i'm sleeping she's what I dream about. I don't know what to do! We have kissed a few times, and i have really enjoyed it. We have talked and though I don't know even know half as much about music as she does i really enjoy talking to her. I have promised my self i would never date a born again Christian and yet here i am... Obsessing over one. I know i might not get to make love to her ever, and even if i do it might not be until/if we marry, but still, i can't seem to think about any other girl in that sense. All i want to do is talk to her, be with her, cuddle with her, kiss her, and hear her voice. But this can't be good. Cause i highly doubt she is as much of a fool as I am.
