Provided he eventually comes clean and wants to get sober again
A healthy action, just for this day, could be too completely take this thought and scrap it!
One day at a time.
Protection of yourself and your child needs to be the priority. What can you do today? An Al-Anon meeting? Plan dinner with friends so you and your daughter are in safe, supportive company? Pack bags and think about a trip for you and your daughter? A new action could be sorting things out physically to pack two bags and give them to a friend to keep with them if you become aware of it being a good idea to temporarily "move into a safe space" (as in, the atmosphere here is toxic and daughter and I could maybe benefit by physically leaving and being somewhere else for a few hours/moments/etc.)
