Some people change, he probably doesn't want anything to do with you. I would give him space and not bother him or contact him whatsoever. My ex was polite to me when he and I had first talked in 8 months but he was just being nice that's all but who cares I'm not with him anymore. My ex is nice but also rude so I don't talk him whatsoever. Some people change, and he is probably acting like that because he may still have feelings for you just doesn't want to show it, who knows. Just don't pay him any attention I would just ignore him if I were you.
