how can you go dark when there are kids involved its too hard. are you his friend i mean can he see the changes in you? do you validate him and make him feel good about himself and thank him when he brings the kids home or give you money? do you ask his advice about things and act like you really care about what he has to say. or do you react each time he is a jerk instead of letting it go ?your marriage is not hopeless but you are going to have to be the grown up as he is still acting like the teen runaway.
