Tamma - This person MUST be restrained from contact with you. If he's done it once, he'll do it again... He may choose you as a repeat victim, or he could choose another.
Either way, it's a lose-lose situation. You can't rely upon friends to resolve it. You need to avoid any contact with him yourself, or you can pretty much count on a repeat performance. Even if your well-meaning friends try to help, it's not going to stop him.
If he's verbally attentive to you, as you say, you're treading on dangerous ground. Also, don't allow him to demean you. People who demean others are doing so to give themselves an escalated sense of self esteem. This guy obviously has none.
If you don't want to go to the local police, then please.. please.. please... go to the campus authorities. You have to stop him.. for your own sake as well as his other potential victims...
Sorry for the ranting and rambling here... I just get pretty irked at situations like this one... Take care, my friend...
