If that is the way it has to be, then I agree that the best thing for you to do would be to keep busy and out of the house as long as possible. I myself do not think I would allow this to go on that long. IMHO, it allows him the luxury of cake eating, even if you are not included in anything but the TV watching. It's like, every other weekend he gets to come home and play Leave It to Beaver's Dad, and then he gets the next 12 days to play house with OW. Just my opinion, though
