mle,
it looks like you have a great mix of suggestions from sober As and Al-anons. It seems the running theme is: Keep It Simple.
As an Al-anon, I agree with the others who say he is sick, too. He is obviously filled with resentment and it will take a program of his own recovery to work that stuff out. But it takes time.
In the meantime, simply answer truthfully ONCE if he asks you about drinking and then, as was suggested, if he keeps it up, walk away, go to a meeting, make a call. Whatever it takes.
Congratulations on your sobriety.
p.s. I'll also say that if he has stopped doing the "breath test" on you, that may be an indication that he heard something in those few Al-anon meetings he attended.
