Is it bad that I don't like my crush anymore after finding out he is too "nice"?

Whenever I talk to him, he is super sweet to the point that it gets kind of annoying. I feel like a bad person for saying this but his kindness sometimes gets on my nerves a little. I'm personally not the nicest person in the world and talking to him makes me feel awkward.

Thanks for the answers. I think I find him "too nice" because he rarely jokes around and when he does, he apologizes thinking I got offended by it. I think I feel awkward because I know I don't deserve him.
