I think we cause our own detriment when we make the decision to stay in unhappy, abusive relationships. I know I was subjecting myself to misery by being a willing participant in an abusive marriage before I made the decision to separate from my husband and stay separated.
Your wife is causing her own detriment by her drinking. I understand that you are unhappy with her behavior, but is your wife making any attempt at sobriety? Does she acknowledge that her drinking is a problem? If she isn't, then why would she change? While this lifestyle doesn't suit you, this lifestyle is suiting her alcoholism fairly well.
