I'll tell him what the family activities will be. He can participate or not. I won't spoon feed him, remind him, chase him, etc. He either finds it in his choice to participate or not. I'll try not to get angry or react regardless of his choice.
But this is really BS. But you are all right--I wont give him the satisfaction of seeing me lose my cool over it. ALl he'll get or see is tepid availability and moving on down the road.
