Alanon is hope for change for you (and me); not the alcoholic. AA is for the addict. Alanon is for the friends and family of addicts. The theory is that when the friends and family of addicts change their behavior, the addict HAS to change their behavior as well because their friends/family are no longer inadvertently enabling them to continue the addiction. Understand? If not, attending more meetings will help you understand.
And there is no such thing as happily ever after. There is just the ebb and flow of life.
