Hi HotPeppers,
It takes a lot of courage to take the steps that you have already taken. I'm in the same situation as you. My W drinks an average of one bottle of wine per night. More on weekends. I started noticing when our wine rack went from full to nothing over the course of a month. Then she would come home with a 6-pack of wine from the market.
Is my wife an alcoholic? Tough question to answer. What I can say is that her drinking has become a problem for me. That was enough to get me to start posting here and looking into al-anon meetings.
There are many wonderful people here with far more experience than I and much wisdom to share.
Please keep posting. You'll get a lot of support!
