I'm sorry you have had such a hard time today! I hope you can keep in mind that all his talk is what we call "quacking", an active alcoholic deflecting any and all attention he can away from his problems/behavior by accusing the nearest person....in this case, you.
I hope you are able to hire an attorney. It seems as though there will be no productive way to negotiate with your AH directly. Certainly, it would take a lot of the verbal abuse out of the mix.
Hugs, HG
