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 অথবা talk to someone without আপনি standing over my shoulder? Can আপনি not plant yourself in front of me so আপনি 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, অথবা 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 ফেসবুক Chat):

Him: I just got back from a class at my temple for confirmation (Note: he ব্যক্ত this without me asking. I just ব্যক্ত 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 ব্যক্ত "brb" with no intent of returning to talk to him. I was kind of insulted দ্বারা this, and I really pissed off about it (and I still am). I'm considering blocking him. Do আপনি think I should just forget about it? অথবা do আপনি think I'm right and I should block him? (Just making sure I'm not overreacting...)
