You might consider this approach, adopted from Robert Meyers' work:
Tell him in calm, reasoned voice that his behavior is bothering you. Request he stop doing this. If he doesn't stop immediately, tell him you will be leaving for the evening (or day, or morning, etc) and will return later. You would, of course, have to have someplace to go to, so you might want to plan ahead of time. No need to "get him into treatment" "take some meds", etc. If he asks you why you left or how to keep you from leaving next time, you can let him know that you don't like being insulted/abused, etc, and you don't feel safe or comfortable while it's happening, so you are just going to leave the house for a few hours until the alcohol is out of his system (most people can process about one drink/hour). If he wants you to stop doing this, then he will need to stop doing what he does. The important point is to focus on his behavior, not on him as a person or his character or diagnosis, etc: "When you have had a drink, you say things to me that insult me and degrade me; I have decided that I do not want to put up with this anymore. I still love and care for you, but I will not be staying in the house while you are doing this."
