If he does not love you for who you are, then he is not worth it. Don't do anything to change yourself for anyone at all. That's if he lost interest, although if he still is crazy over you, he may simply not be showing it. I always keep this in mind with guys:
"Just because someone doesn't love you the way you want them to, doesn't mean they don't love with everything they have."
I don't know who said that quote but I always find it comforting whenever I have my doubts. Try to subtly get his attention every now and then, but if he doesn't take notice, just straightforwardly talk to him. No hints, no games, just be honest and plain with how you feel; and if you do that, then he may also be honest and plain with how he feels.
Good luck with him though sweetie!
