Hi Postcard,
I can't comment on your wife moving out for 6 months or so but if this is what is needed to get sober. Your wife sounds like she is right behind you and your family. You are so lucky in that respect.
I just received an email from my AA sponsor telling me about a woman in her 60s who has a major drinking problem, living in a developing country, falling down drunk, septic ulcers, flyblown and still can't see, won't see the problem.
She is in the grip of alcoholism and perhaps it's too late for her. I am writing about this because it really affected me but for the grace of God, I could be her.
I woke up to the madness and got support and my life is better than it has ever been my health, my energy.
it will take time to get to the point where alcohol is seen as the poison it is for some of us. But you will get there and be free.
Love
Caihong
