No one chooses to be an alcoholic qaz, nor chooses the issues that lead them to destructive behavior. I notice that you have mentioned this a few times in your postings. That thinking may keep you stuck. I see that you feel compassion for this man, but we all have to take responsibility for ourselves. Ultimately, no one can save us, except ourselves.
My therapist once told me that I wasn't responsible for things that happened to me as a child, but I AM responsible as an adult to build the life I want.
