Not to be possibly unhelpful but I feel this is just one of those things that can't be explained unless your friend told you straight up. There could be many a reason or something as simple as, "I don't know."

Not to sound weird but sometimes things aren't that creepy, really creep me out or make me feel weird. I can't explain why I feel that way, I just do.

I'm sorry your friend is acting this way, have you just asked him?
