I really feel for you. I have begun to pretty much go everywhere without my alcoholic partner. He ruined my daugher's first birthday party this past january. It broke my heart. Plus I worried about the birthday party (and his being drunk through it) all the whole week leading up to it. Next year I plan to have her birthday party during the week while he is at work. I am trying to avoid allowing him to ruin important days with his drinking. I don't want my little one to grow up with these memories. Good luck to you. I would agree with those who said to go alone and then tell him why if he asks.
