Shes moving to another school, and you missed out, I'm sorry for you man. But this is a character building experience. Next time a girl you like comes along don't wait. Tell her you like her!
I confessed to a girl once during time I had as an exchange student, I had a lot of trouble getting the guts to do it, but I told her I liked her. She rejected me but I didn't care! I was happy that I had gotten over being a pussy and actually bothered to confess to a girl. If I hadn't asked her out, I'd have regretted it like fuck.
