I am absolutely convinced that his recovery will have very little if anything to do with you, and will not be sustainable if he does it "for you." No one can predict or control that little glimmer of spiritual awakening in another person.
My AH began a 4 year period of sobriety one random day. I suspect it had something to do with some words he said to my son that he may have regretted, but he never shared with me why he woke up one day and said "Enough!"
I love the idea that it's all on the alcoholic to choose recovery, because it takes such a load off my shoulders to feel any responsibility for their recovery. OTOH, I also firmly believe that the BEST thing you can do for them is to live your own life.
I would definitely say that includes keeping your family close--good for you for not tolerating his abuse with regard to your family.
