Thank you for the replies. When I try to keep the most rational mind I can in this situation, I think I do really know, deep, deep down inside of me what I really need to do. Obviously not the easiest choice to make. But I know I need to stay firm in my feelings of not wanting to be treated poorly any longer and not wanting to see him continue to deteriorate in many ways.
I think finding addict support groups in my area will be beneficial. I wanted to start here to make sure if I did get responses, they weren't of people telling me my reaction and thought process was crazy (not that I truly thought that it was). I think I just want to hear that it'll all be okay.. but maybe that was in a dream..
Thanks again for the replies and advice.
