Sounds like it's time for you to start taking care of YOU. You can't make someone quit drinking, and frankly, your life with him sounds pretty depressing.
I'd suggest, as a start, learning all you can about alcoholism--it's not as simple as going to rehab and getting "fixed." It is a major lifetime commitment to get sober and stay that way. There's a lot of good info in the "sticky" threads up top.
Second, I'd suggest you find an Al-Anon group and start hitting some meetings. They are for family and friends of alcoholics who have been affected by someone else's drinking. It's a good place to begin getting a handle on your own life and getting your head clear so you can make some good decisions about how you want your future to look.
