I've been thinking also maybe my "addiction" to him is as strong as his addiction to alcohol. Anyone else ever feel this way?
You hit the nail on the head. I've been sober 21 years and going to Al-anon half that amount of time. To me codependency is alcoholism without the booze. You may want to ask yourself if this is what you want for your life? Because with an alcoholic what you see is what you get. In all my years I've never heard of an alcoholic say they quit drinking for someone else or because of someone pointing out they have a problem. Alcoholism AND codependency are steeped in denial. His denial that he has a problem and your denial that the situation will improve or you can get him to stop drinking.
Best of luck!
