Rigger,
I can only speak for me but I dont know that anyone could have made me quit drinking. Trust me when I say my wife tried everything too.
For me there had to come a point in time when I was beat down far enough, scared enough, and so exhausted from drinking that I wanted to quit for me.
My marriage survived it but just barely. I have been married for thirty years.
From my wife's stand point I'm sure she would say get out now. The road ahead is to hard. Only you can answer that part of the question though
