It was me who guessed you were doing the “busy, busy, busy” stuff.
It’s a “coping” and distraction exercise.
But it is counterproductive - because it is all of this “busy” stuff that is enabling his alcoholism - not the having a civilised glass of wine with him. There are zero natural consequences for his emotional abandonment and detachment from the family - because you accommodate and pick up the slack and cover up - freeing him up for even more capacity to drink more. I understand that this feels like your only option and that the inadvertent enabling was the very last intention.
And he has emotionally abandoned the family because his mental focus is always preoccupied on the next drinking session.
Yes you are trying to do all of the things that your DH is choosing to not do for your DCs.
I have lived your life - down to him sleeping on the sofa. We have come through it but it necessitated us separating with the intention of divorce for him to pull himself up. It required him doing a lot of personal therapy, going 100% teetotal and me doing a lot of decent therapy.
But the dynamic changed with MY actions not his. I wish that I didn’t spend years fighting with him about it, trying to control and manage him where I turned into a screaming loony and lost myself - as a mother, my own dignity and my MH. Al Anon taught me about “detaching with love” to save myself, my family and ultimately him. He had been teetotal for 7 years at one point - but our RS was always tense during those years because he was white knuckle riding it. When he started drinking v lightly again I wasn’t too worried. But it’s a progressive disease so it spiralled.
This time it was the family break up and therapy alongside zero drinking that has got him through the last 5 years.
Whilst you are “busy, busy, busy” you are at the same time 100% sub consciously aware of his alcoholism - YOU are also preoccupied - which means that you also can’t be fully attuned to the minutiae emotional signals that your DC are giving out - because you are keeping everyone too busy.
So your DCs are not getting the optimal emotional support that they need to develop from you or your DH. This was the reason I separated because my DC deserved better.
Another thing that was important - at the time my DH hated the term alcoholic - he was happy to say he was a “binge drinker” - although never declared he was a “problem drinker”. All denial - although now he is v open and says that in his active state his whole being knew he was an alcoholic and his whole purpose was to deny it.
My learnings consistent with others experiences from on here and with Al Anon is that this is their personal journey - any nagging, managing etc is futile and enabling. They need to hit their own rock bottom and all of the lovely things you do for him are preventing him getting there. Also your DCs are being sold short - at the v least there is low level emotional neglect.
So in your shoes I would do all the research you can on addiction / alcoholism from Al Anon (online) or other services so you can “see” what is happening and where this is going for you and your DCs.
I wouldn’t waste months and years cajoling and nagging. I would state the facts and give an ultimatum. I would emotionally detach and then follow through with actions not words. That’s the best you can do for your DCs, you and ultimately your DH.
