I don't know the full story of what's happening in your life. But, you're small description also shows that your husband is trying to numb his pain right now with the drinking. It may not be your favorite way of getting away from it all, but it is a technique nevertheless.

My point is that: While your hub came off in a harsh way to you. Perhaps it was the alcohol bringing out his fear & frustration with the situation at home. It is a possibility worth considering. Especially if you are serious about ending your marriage. It's a hard road....no doubt!
