Guy 1: Forget about him, he is jsut being a time waster. Next time he phones, texts whatever, don't reply. He is just trying to mess you around.
Guy 2: Tell him how it is. Either he decides whether he is willing to make a commitment, or you go and find someone who will actually treat you right. Seems to me that the guy does not seem to be getting over his ex, so while he aint in a relationship, he does not want anyone else to be. He seems like the person who wont let you go into a relationship, but when he finds someone, he'll quite happily brush you off. :\
