When i realized that I had given up hope of him ever becoming sober. I read through the threads here and on a similar forum on a different website and saw how other people had gone through the same thing with addicts that I did only for years longer.
At the same time I read "codependent no more" by Melody Beattie and that was a turning point for me. I realised how much I had lost myself and how to set boundries and get out of the situation.
I am much better off now.
