If it makes you feel any better I've also been there and understand how you feel when you say that you felt used and violated. It's only natural to feel that way when you feel you've been taken advantage of. It sure will bring you back to reality quickly. Don't worry though, it only gets better from here. :smile:
Blacklisting the man would be the best idea that I've heard. I doubt the same man will try to contact you, but if he does, let him know that you won't play until he pays you what he owes plus interest...lol.
