I get the feeling that you like him because he makes you feel something. Girls go on date after date with guys asking the exact same questions like they were all given a script. This guy comes along and although the emotions you feel are negative, they're balanced out by the limited good that he throws you. Within the pick-up community, this is known as push-pull. He pulls you in with private lessons and free anime, then pushes you away with childish comments.

The choice you have is to either give him a piece of your mind, or accept it and learn to deal with the way he is. Either way, don't expect him to change.
