I think it was someone here who once told me that trying to reason with an actively drinking alcoholic was like asking your dog a question and waiting for a written response.
Once my wife had gotten good and sober - like a year into sobriety - she adopted that line and loves it. When you are trying to reason with an active alcoholic everything you say is going to lead precisely toward them sobering up and that is NOT what they want until it is what they want.
Hang in there
