Is he a jerk or what?

You need to tell an adult. A counselor, a teacher, a parent. He sounds like a potential danger.

He's obviously got really serious issues, so be careful.

What you need to do is make sure he understands that you and you alone are the one making the decision that you dont want to talk to him. If you have some guy go and beat him up, his crazy *** will start saying things like "Oh, is it because of this guy? Is your new boyfriend (even if he's not your boyfriend) making you stop talking to me?". Dont give him any room to rationalize things like that. You need to tell him one of the main reasons you arent with him is because he's clearly got some issues where he cant deal with his own emotions, and he needs to get some help with that. Try not to embarrass him in public though, cause he'll probably get really upset and he may take it to the next step (trying to hurt you or get back at you for making him feel bad). Although you should make it clear that you and you alone dont want to be friends with him, make sure that your other friend is standing somewhere nearby, in case Mr. Psycho decides to do something stupid.

Get away from this guy, nothing good can come from staying friends or being nice to him.

Try not to get your new guy involved (not yet, anway). You just met him. Report this to your school principal's office immediately. Tell them you're being stalked and demand that somebody sit down and talk with him because you're scared. This way, you've done two things "Made an official record in case something worse happens" and "got an adult to talk to the aggressive jerk".

Remember: "He is trying to wear down your resistance until you let your guard down and say yes". This is his logic.

'If I keep on pressing her, sooner or later I'll get her back'.

If you go to an adult, and have his parents contacted, he should back off for good. If he doesn't then he is a real nut case, and you should be with a cellphone and a school mate at all times.

Well, I would not have your friend beat him up!! Remeber that violence dosen't solve anything!! But you do have a problem. What I would do is continue to ask him to leave you alone. Also go to a teacher or someone at the school with authority that you trust and let them know about the issue. So, that way they can keep an eye out for you.

I'm not sure I agree with why you broke up with him in the first place...

but...

talk to an adult you trust as soon as you can. He sounds like he's a bit unstable, and might possibly do something crazy. A broken heart can be a powerful motivator. Other than that, just try to gently but firmly avoid him, until you can talk to somebody about this. I may be reading too much into this, but it is better to be safe than sorry.

Stalker says what? If you actually feel like he's a lose canon, TELL people, warning signs are often over looked. Really, don't blow it off too fast. And remember, you won't have someone around you all the time, not trying to scare you or anything, but with everything that's happened lately, you can't be too careful. Tell an adult, make them aware.

Yeah i think he's a jerk. I think that if he is stalking you outside of school you should call the police. Even if he is just stalking you in school, if you have a police officer in your school you should have him stand outside that classroom until he stops coming around you. I don't think you should have your friend beat him up in case your ex gets real ugly with you. I think that he is being a total jerk. If he;s acting like that he needs a counselor.

Leave him alone ignore him act as if you see glass in front of you.He is not there. By talking to him negative you are still giveing him attention what he wants. NO don't let the new guy beat him up. You both just walk away ,as if he were a post set in front of you.

He sounds quite unstable. The problem with getting your boyfriend to beat him up is that your b/f may then get arrested and charged by the cops and nothing will happen to the guy stalking you.

The sensible and correct action is for you to tell your parents and /or teachers about this and they will advise you appropriately.

sounds like a guy holding on to a relationship that you don't want. I mean he will get over you. I'm sure some other girl will come around and he will forget about you. Just hang in there. I Am sure he just thinks he is in love.

In this day and age you can't be too careful. Visit with your local police department and check in with the womens resource center where you live. An ounce of prevention is worth a pound of cure.
