AlAnon, AlAnon, AlAnon...The reason I say this is that you need some sanity in your life. AlAnon can provide it. I have seen women live in such situations with the aid of Alanon (for various reasons not leaving or asking him to leave) very successfully. I mean, jsut kicking the guy out, or you leaving won't really SOLVE your problem, unless you have no kids together. You need to learn about his illness, whether he chooses to get well or not.
The main thing is that it can give you peace of mind. There are meetings all over. You will learn about the disease of alcoholism, boundaries, detaching with love, being responsible when all you wan to do is run...and so much more. And there is so much love there.
If you choose nto to go the 12 step route (although sometimes it leads to the drinking partner ALSO going teh 12 step route, which means MUCH more peace and even GROWTH and quittting drinking), please at lest see a therapist, such as an MSW counselor (they are called different things in each state depednign on what their licnece is abbreviated as...here it is LCSW. MSW is the degree they have.)
There IS hope. Just remember that, and don't let it go any farther, to where you jsut want to give up, i mean if you really loved this man. You CAN have a good life. It may not be with him, but your kids WILL need help, too. There is a group called Alateen. Kids need help with it too. They dont' just "bounce back."
Good luck
