Hi. Alcoholism is best diagnosed by the problems that someone's drinking causes, and based on your description, I'd say your wife qualifies. Your best resource is alanon, and your wife may be to the point of requiring medical assistance to detox. Your anger is understandable, as alcoholics, we usually hurt the ones that love us the most. Your wife may be a wonderful person in all other respects, but continuation of her drinking will likely erode these away in time as well.
