What should i do?

So there's this boy I used to mess around with and I've known him since last september of 08. He went to my old school and he's a pervert lol. We basically did everything but have sex. This year I'm going to a new school and I decided to 'get rid' of him...

because all he caused was emotional problems for me towards the end. I mean he was really nice but I couldn't be able to do stuff with him and not have a commitment or somethin. So I haven't been talking to him, and he keeps calling me. On my aim I set it for only people on my buddy list can contact me and I deleted him off my buddy list. He left like 5 voicemails within a week and a half and asked why I was ignoring him and idont know how to tell him. He left a voicemail earlier this mornin tellin me he misses me and asked how many times he had to call. He called me like 6 times today. I feel so bad, but I don't wanna ;'fall' for it. He told me some personal things about his sister and his past, etc. Like he trusted me and I jsut ran away and gave him the f*ck you. If we took our 'relationship' with each other any further, he would expect sex and I dont want to make the wrong decision (esp. having it with him for my first time).

Should I text him or email him back and be like: I dont think it's a good idea to talk to each other. I think your way out of my league and I dont think I could ever end up being just friends with you.

Or somethin like that...??

or should I change my number?

u have to tlk to him. get it all out tell him how you feel. base your decision then on how he reacts. if he says he will wait for sex then your in the clear

who knows maybe you guys shud hook up and c what happens and if things don't work out then break up wit him or just let him know that you just wanted to mess around that you wasn't takin nothing seriouse but you appreciate his friendship
