Should I block him?

He's this really creepy guy I met at camp, who wouldn't leave me alone, kinda stalked me around the camp to the point where it was like, "Um... personal space? Can I please actually walk somewhere atau talk to someone without anda standing over my shoulder? Can anda not plant yourself in front of me so anda can just stare at me?" It was REALLY creepy. But I felt kinda bad for him, so when he friend requested me on Facebook, I accepted.

But I'm thinking that wasn't so smart of me now.

First, I know for a fact that he likes me, atau at least as much as a person can know that somebody else likes them. (He told me he likes me, and I rejected him. He's too creepy.) So he knows that I'm Jewish, though he never revealed his religion to me. Today, I was talking to him, and the conversation went like this (this is copy-and-pasted from the facebook Chat):

Him: I just got back from a class at my temple for confirmation (Note: he berkata this without me asking. I just berkata hi and he kinda randomly wrote this)

Me: um, they dont hav confirmation in judaism... and temples are jewish...

(A significant period of no response...)

Him: Its a different kind of confirmation

Me: oh? wat is it?

(Another significant period of no response...)

Him: I dont know. All we do is discuss jew things

At this point I berkata "brb" with no intent of returning to talk to him. I was kind of insulted oleh this, and I really pissed off about it (and I still am). I'm considering blocking him. Do anda think I should just forget about it? atau do anda think I'm right and I should block him? (Just making sure I'm not overreacting...)
