Now the question is how do I call her out on her drinking?
Wife I have been afraid of telling you this in the past because I was afraid of rocking the boat but now that I've moved out, a lot of things will be changing with respect to you and I.
You drink too much, I think you have a drinking problem.
And then expect her to explode into a million pieces and call you every bad name in the book, alcoholics rarely enjoy being called alcoholics, your wife doesn't have a great opinion of you now, watch things get worse, a lot worse before they ever have a chance of getting better.
