Your kids can feel the tension, don't fool yourself into thinking yo can smile and hide it...

My advice is to take yourself AND the kids AWAY from the H as OFTEN as you can ... treat him as if he has a disease adn you don't want your kids to pick it up...

Your H's are both using your kids to get away with their cake eating... It's time to stamp that out and SHOW your spouses that you don't tolerate disrespect
