My husband still drinks, although he is cutting back some. In the past when I have stopped he has been neither supportive or unsupportive of my quitting.
When I told him I had ten days yesterday and be fist bumped me and was generally happy for me. I told him I am not planning on drinking anymore, and he said you can still have a glass of wine every now and then. I told him I can't, because it is never just one, then he said well then good for you for not drinking.
I don't know that he completely gets it, but I think he is starting to.
