Damn!! Thats a long ass post!! I have read your other post in here about the situation your in. I don't know the guy personally, but if anyone here does they should tell this guy whats up. I think you've waited long enough and I would go ahead and try small legal action. Contacting police and having them get in touch with this guy might wake him up a little bit. I understand if he has had some small medical problems but he shouldn't be promising things he can't fulfill (at least for the time being) You SHOULD be mad. I wish you luck in getting this all settled.
