I used to do the same, printing my AHs debit card statements from our online banking. Literally, every other purchase was a liquor store or bar. As far as your kids, I would take everyone's advice and gather proof so he would have supervised visits. I say this because my AH has two kids from a previous relationship and I spent countless Sundays driving them the 15 miles home after they came to spend the day with their father and he spent the day with Budweiser and football. I know it was enabling but I'm 99% sure there were many a night he would have wrapped them all around a telephone pole.
