There was a thread some time ago along the same lines but I can't find it. Perhaps someone else who remembers that thread and is better at searching than I can find it?
I consider mine a happy ending because my life is better and I am healtheir and happier. Not the definition of happy ending you seem to be working from I know. But sometimes we have to change our definitions when reality smacks us in the face. I would at one time have thought getting my Ah sober and staying married and living happily ever after was the definition of a happy ending. No more though
Once I accepted that my happiness depended on no one but me, that I was not in control of xAH and is alcoholism, and began working on me, my happy ending started.
