Complicated situation..., What should I do!? Options

[ficklenesswhatev...]

Okay, there's this guy that my friend knows, and I talk to him over AIM. He seemed really nice and stuff so I talked to him a lot, we got along. I started to like him, but he was really into this girl Stephanie who didn't like him at all. She had a boyfriend, but she kept telling him she liked him. Meanwhile, the friend that introduced me to him knew I liked him so she told him bad stuff about Stephanie and good stuff about me. Now he likes me but is all depressed and stuff and cuts. He's really dependant on me, like if I dont call or get on AIM whenever he wants he says he'll kill himself. I don't like him anymore because he's freaking me out, and he's telling me he's in love with me. (We haven't even met, and he's saying he loves me.) I've been avoiding him because he really really freaks me out, but today I had to talk to him. I told him that I couldn't have him put a guild-trip on me whenever he didn't get something he wanted. And he put another guilt trip on me. I told him to stop, because I don't wanna hang around or be friends with people who are constantaly making me feel bad. I signed off saying I might do something drastic. I think he meant commit suicide or something, but I wanna tell someone he cuts. Our school district has a program that you can call annonamusly and tell people about that kind of thing....but his parents know, and aren't doing anything about it. Should I get the school district involved?

Sorry if that took forever to read..but it's really complacated.
