Two words that jump to mind while reading your post are "insecurity" and "controlling", referring to your husband.
If your being honest with yourself regarding your drinking habits, then I would be asking; "Is your husband controlling in other aspects of your life also?"
Does he question why you need to spend time with friends?
Does he question how long you were out and/or with who?
Or is there something alcohol related in your husbands past that you may not be aware of?
