You aren't going to be able to "protect the peace."
It's just going to be his way. To a drinking alcoholic everything is a personal attack. He's mad at you, mad at himself, mad at the world but god forbid he should actually change.
Sorry, but if you choose to stay it's only going to get worse. What do you see as the final ending to all this that doesn't include you tying yourself in knots and him drinking anyway?
