RL, it sounds like he's sucking you dry in so many ways, financially, in energy, emotionally. You probably never thought you would become one of those women, but you can get used to the abuse and not know how to move on.
As the others have pointed out, he's not interested in recovery. I'm a sober alcoholic, and I know it can take a long time to get to where you want to quit; no one can do it for you.
He doesn't sound too helpless to me. He's got a comfortable set-up with you doing all the work, paying for most of it, taking his abuse, and for all that he still gets to drink. Why would he go anywhere? You might want to start planning how to get him out, and when to change the locks.
Go to Al-anon, and if you can find the strength, kick him to the curb. Be prepared for lots of apologies and promises if you do, but watch the actions rather than listen to the words.
