Thank you all. I know I need to give my son a good life away from this. I read the post on "Breaking The Cycle" and it really spoke to me. I guess a little voice inside of me wanted someone to say, "No, stay and work it out! Do this! And he will magically change you guys will have a happy family!" But the smarter me knows that for him to ever change, he has to first admit he has a problem, and I do not see him doing that anytime soon. And things have already became worse over time, I do not think I should stick around to find out how bad they can really get.
I appreciate all your words! It is great to hear encouragement.
