I need relationship advice!!!!!!!!?

I am worried about going to my winter dance. My problem isn't my date, but this other guy from school. He's always making excuses to be near me and i always catch him staring at me. The last time i went to a school dance this guy kept staring at me all the time. It really creeped my date out! He has a gf, and claims he ';loves her'; but then why does he do things like this. He will also later im me and bombard me with questions about my bf, and he gets really jealous about it. He almost got into a fight with my last bf just because he was going out with me. HELP! What should I do????I need relationship advice!!!!!!!!?
Seriously? You need to confront him (preferably in front of his girlfriend) and tell him that he needs to leave you alone and that he is creeping you out. If he really loves his girlfriend (which I doubt he does at his age anyways), he needs to stop staring at you, stop getting jealous about you having guys in it and to just stop acting weird towards you. Confront him, or it'll get worse. We never think that those bad things we hear about on the news will happen to us until it has already happened.
