If you go to the top of the Friends and Family of Alcoholics forum there are a number of threads that are separated from the active ones. Most have locks on them. They are called stickeis because they are 'stuck' up there at the top so they never go away.
The couselor I saw specialized in addictions and understood codependency and what it is like to be in a relationship with an alcoholic. I think it really made a lot of difference.
I'm not really trying to tell you anything about this relationship. Mostly I am trying to say focus on yourself and not him. That is where you will find healing no matter what happens. Place hope in yourself. That doesn't exclude him from your life, it makes you a whole and content person within yourself.
Co-Dependent No More is a book that I read and also found very helpful.
