I would suggest not rescuing him on the days he is supposed to have the kids. He needs to figure out what to do with them. I know they are your kids and you love them but why does he get to live the way he wants with you constantly giving??? You may not care now but there will come a day when you will.
Maybe they will spend the time with Dan's Mom or at daycare but they will be fine and so will you. He needs to get this and maybe in a way so do you.
