Oh, but we DO know Tony. Very, very well. Does he really think he is a special unique snowflake alcoholic? He isn't, and the story is all too familair to many of us here.
You are a new mother to a brand new life. How exciting! THAT should be the focus of your energy--not some deadbeat alcoholic who is now muddying up an already painful family dynamic. Keep putting as much physical and emotional distance between you and this painful situation, and the alcoholics, as you can and you will be fine. Start making the choices today to bring about positive change---maybe a different living situation would be a good place to start?
