yeah dude honestly i think most people get this way when they are young. I really dont believe you fully understand love... honesty i think its the lust of your youth coming out.
I think the best thing is just stay in touch with her on like myspace or call her from time in again. At your age you should just be fucking every girl you can.
I've been down your road before and its not fun, let it fly and maybe someday it will come back. I really think your too young for a serious relationship, you need time to grow or later you will be bitter.
