I see your situation and matter. I would like to provide some advice and suggestions. First, I would consider that you encourage the alcoholic family member to reach out and ask for help. Since there are young children involved, I would consider communicating with the Child Protective Services. Also to find some psychological or psychiatrical services for them and share the contact and referal information. I would also find and reach out to close friends who know him very well to assist him with getting back on his feet. I hope this helps.
