Sorry, didn't mean to drop out of the thread, got bumped by a homework-pleading younger child.
It is very interesting to see all your thoughts. I wouldn't want you to think I am just overlooking DH's drinking. I have in the past LTB twice, the last time a decade ago, but it didn't stick -- partly because he promised to stop drinking (and on one occasion did stop for four months, his record), but mainly because I felt that creating a situation where he was in sole care of our young children during visitation rights would be even worse. As I say, he is not otherwise a bad man. And he does know he has a problem. He simply doesn't have the will to do anything about it, and though this is still the only thing the DC have ever seen us fighting about, it is sadly clear to me that I cannot control his behaviour if he will not.
And yes, it has had its inevitable impact on our marriage, and I have some many times dragged us both to marriage counselling and myself to psychiatrists. Fortunately, though, he mainly becomes more and more quiet and sodden on the sofa, and we all retreat upstairs and leave him to it.
I feel the only thing I can hope to manage at all is DC's reaction. They know this is not normal. The drinks DS1 took last night were (good point for asking) very small ones, certainly not pub glasses! I think I may show him this thread, though. I have already talked it through with him once today. I told him I didn't think he was drunk last night, that I trust him and love him, and understand it's natural to wish to grow up with his peer group. But that he should know he may be at much higher than normal risk of alcoholism, and I want him to be very, very careful.
This is not something that can be fixed in one conversation, though. And I have yet to tackle my husband. I think, or hope, that while in denial about how he is killing himself, he too loves our children and doesn't want them to copy this behaviour.
