Well, God bless you you're not detached yet, but it's nice to know you are working on it. On another note, AA is not for you-- it's for him. Alanon is for you and you might consider giving it a try-- it saved my life. Keep an open mind, try at least six meetings before deciding if it is for you (some different), and go from there.
Also, and I'm sure you already know this, you didn't cause his alcoholism, you can't control it, and you can't cure it. But, you can contribute to it by enabling the behaviors and shielding him from the consequences of his drinking (and it sounds like you are ready to stop enabling).
Take care, take what you want, and leave the rest.
