Dear Stubborn, as you say you have set the boundaries and your AH knows what they are. If you are ok with caring for him whilst he heals from surgery that is your decision, after all you know all that is involved and I don't.
My xAH is still a part vegie in hospital, and if he doesn't die there in next few days will be back in Nursing home again.
I am still with ABF, who has been sober for 37 days Praise God.
This morning he flew 3000 ks to visit friends and do some business, and as the plane took off I prayed that whatever happened, if he drank, I would have the strength to say enough. And stick to it.
He rang me just before boarding the last plane and it was the first time he had been alone for hours travelling, and not had any beer. He was tired, not feeling too good but was sober.
Like you I can only hope and trust that he stays that way, hard as that will be with drinking friends, but hope I will.
God bless you and your family and your husband at this time.
