My mother has said to me numerous times, when you ignore it you make it ok for him to drink more you need to say something to him hes walking all over you.
You know this isn't true if you're going to alanon and working a recovery program. Stick with what you know is tried and true. Family wants to help, but at times what they offer will do more harm than good. And remember, blood is thicker than water. They'll defend a brother or sister to the death but if you're not blood, they'll hang you for the same offenses.
Keep up your own good work because you know it's working for you.
