Thank you, everyone.
I did tell my husband about my conversation with our youngest, and he did talk with her, and seems to have addressed her concerns sufficiently for now. He had already talked with our older one. I will check with the girls to make sure they know they can go to him or me with any questions or concerns. We also need to talk as a family, I'm sure, and that will come.
Yesterday, I was talking in passing about going to an Al-Anon meeting, and I that set off another light bulb in his head about the impact of his drinking on us. Today he said he brought up the subject at his AA meeting, and I can tell it is on his mind. We'll see how things progress.
