Al-Anon save my life too. A note about it-- it's for you, not him, and sometimes the alcoholics in our lives don't want us to go to Al-Anon (though some do, as my wife did). Regardless, go to at least six different meetings before deciding if it is for you, and keep an open mind. I say this because, I initially used the higher power thing as a reason not to engage. It was a big mistake, and prolonged my misery for years longer than I needed to be miserable.
Along with much of the good information you've already gotten, I think this will point you in the direction you want to go (it did for me).
Take care,
