SR can definitely help you with support if your desire is to quit drinking. Just to be clear, are you saying you still binge every 2 days or so, or was that prior to your outpatient program? Most programs I've seen wont take you unless you have already detoxes.
Getting sober will most likely allow you to make more clear headed decisions about your life. Honesty is also a cornerstone of sobriety, and it sound like you might need to use a little of that in your marriage as well.
