How do I reactivate my facebook account?

I tried to add this one cute boy who I always had problems with and I really like, but I think he reported me because he is pissed that I have my boyfriend still and he doesn't have his girlfriend anymore. I need advice on that too please. Thanks! I ALSO know he probably reported my account so I could not get on it! He has avoided me since the beginning of 10th grade. Now I am in 11th and we practical dated in 7th grade while he had a girlfriend and I had a boyfriend and also we were secretly infatuated with each other and now we cant stand each other. (We only made out though) I am MADLY obsessed with him still and I know its not good but I cant help but think about him All the time. I think I was his first kiss. I am deeply in love with my boyfriend too! I have been going nuts since 2007!!!!!!!!
