GingerCat.....basically, he will be getting introduced to the concepts and fundamentals of recovery.....and, hopefully, learning some tools that he can apply, going forward. Most of all, he will be learning that he is helpless over alcohol, and that recovery is a life style that he will need to live by for the rest of his life.
So good that you are beginning to see a counselor for yourself and are open to going to alanon. that is exactly what you will need for yourself.....as the spouse needs attention as much as the alcoholic.....
My very best cat, ever , was a ginger manx!
