Leave the room, leave the house, do something to stop that fear-of-missing-out thing. Make a list of some go-to activities and keep it in your wallet.
If you can look at it as his illness, not as a party, that would probably help.
I was defining a slip as a 1 day relapse, and a relapse as lasting longer than 1 day. Nothing about slip was I defining as involuntary.
I do agree that I need those temporary boundaries, and I have already told him I will leave the situation under certain circumstances. And it is true to view his drinking as part of his disease and not some fun party.
