I'd agree with this post. All YOU can really do is reach out to him in new and different ways. Unfortunately, relationships by their nature can't be one sided and he will eventually have to make a move to follow you or its not going to last.

Hope it works out in your favor, just remember if it takes a turn for the worse that its really not worth it to dangle with someone who doesn't really like you back. Everyone needs/deserves someone who really likes them back, but who is ultimately up to them.
