It has been half a year and he's still at it. At least he slowed down to changing his name once a week to send me harassing messages after I block him.

So against my better judgment I met a guy from this site. I talked to him for a little bit, but he started bugging me about it non-stop. I thought he was being a little needy, but I figured why not, just to talk and such.
He seemed nice enough at first, but I didn't think we clicked at all. I told him all this, but then he kept harassing me and wouldn't leave me alone. He's now going off saying I'm a fake and leaving postings on another site for men to contact me. I really don't know what to do.

I guess that'll teach me to trust people until I get to know them a lot better.
