Wow- it does sound like he has a long way to go. What really bothers me is that he is saying he doesn't want to quit drinking. If he doesn't want to- he won't- period. It sounds like he is saying he knows he has a problem or might want to quit just to keep you on the hook.
What do you want? Do you want to stay with him long term if he won't stop drinking? What if he won't keep a job? If you can't or won't put up with those things (a lot of us won't anymore) then you may want to seek outside help for yourself and start setting boundaries with him.
Good luck- I will be sending hope your way.
