How do I deal with this guy who OBSESSIVELY likes me? 10 pts? DESPERATE?!?!?

[Ka]

This guy in my class has a huge crush on me but I don't like him like that. He was my friend at first and I thought that was it, than he started getting all cheesy and buying me things. I told him I don't like him before he got the wrong signal and he started saying he liked me since he saw me, that I should stay with him or he'll get depressed and lonely, and for me to be his girlfriend for at least 1 day and ALL THIS SH***T... I told him I don't like him, that I will NEVER be his girlfriend and throw him hints IN HIS FACE about it, but he seriously doesn't get it. It's like he's illiterate.

Now at first I thought he was cool but he found me on facebook, stalked my entire information section, stalked where my friends live, my pictures and it's really weird. He changed his profile picture (which he never had 1 until today) and think it'll impress me..... He kept saying cheesy things like "I want to see you )" even though we see each other EVERYDAY in class.. he thinks he's in love. He follows me everywhere around school if I don't say I'm going home, so I always tell him that. he also has no friends.

And we only met for about 1 1/2 WEEK...... I see him everyday in school so there's no way to avoid this =\ PLEASE PLEASE PLEASE HELP.

He's 19, I'm 20.
Should I get a guy friend and pretend I'm dating him for him to leave me alone?!?!
It's not as bad as him coming to my house and begging me, so no cops.

I just want him to leave me alone =.="
@Stacy, I've been acting like a b*tch, he seriously doesn't get it.
