So, you think you're in love? Why not make a Myspace.com page about it? I'm sure it will ease your pain, just as Myspace.com has eased the pain of many other lovelorn masochists.
You're at an age when you're noticing the wench gender for the first time, and I don't necessarily mean in a sexual way. You may very well be in love, but it'll probably pass as you mature. In the mean time you should enjoy the moment instead of obsessing on the internet, ask her out or forget about it, leaving it to simmer will only hurt you in the long run.
