Would you date someone who you don't consider to be your equal?

I don't think you're being snobby; those sound like pretty legitimate complaints to me. You sound like you have your head on your shoulders, and he doesn't. If I were you, I would spare both of you the heartache and just say no to him. Even if you do agree to date him, it doesn't sound like a relationship that's going to last. Maturity is an important part of every relationship.
