Most Helpful Guy
can't make him realize anything. He doesn't know how lucky he is that his mom has already accepted you. most parents don't accept their kids dates not to talk of being good friends.
I suggest letting it go, he may just be a little weirded out that you guys get along well. keep talking to his mom as friends and very soon he will start to realize how much he misses you and come back. I call it the boomerang effect.0
