LGLG it sounds like you did just what my wife did, she took over, raised hell with me about my drinking, then hit me with the ultimatum.
Troubled all I can tell you is my experience, almost every marital problem we had dissappeared when I sobered up, but that sure does not mean that is true in all cases. My first sponsor and his wife divorced 2 years after he got sober after a 20 some year long marriage.... she said she did not like him sober and she hardly ever drank herself?
Alcoholism can break up marriages big time, but an alcoholic getting sober does not save every marriage.
