Hey, I actually had this same problem recently with a girl I met at my friends house. I thought she was one of the prettiest girls I had ever seen in my life. She lived kind of far away, so it was hard. I was always obsessing over her, looking at her myspace, wondering what she was doing, probally all of the same stuff you do. I hung out with her acouple of times, and I was always trying my hardest to show how much I liked her. She then later started to ignore me, and I think I now realize that being overly obsessive can be very bad for a relationship. I believe that it can really turn people away from you when you are constantly trying to involve yourself with them. She eventually stopped talking to me. If you really care about this girl, I think you try your hardest to stop obsessing, everything happens for a reason. If its meant to be, then it will work out. If not, then you keep searching like the rest of us.
