I'm so sorry for your terrible situation, I can't imagine what you're going through
I'm an alcoholic (now one month sober and working for more time!) and while I was always high-functioning and able to work, I put my husband through a LOT of terrible things. I embarrased him at his work events, in front of his friends and family. He now tells me that he worried every day that I would die.
It kills me that I could do to anyone what you said your husband is doing to you, but I'm pretty sure I did a lot of similar things. I hit my own rock bottom and had to decide for myself that it was time to be sober - I pray that your husband is able to find this for himself. You and your husband are in my thoughts.
