Actually, his "demands" really aren't that bad... but what pissed me off the most is him demanding that you obtain his written permission for medical stuff, but then turns around and says "and I will extend the same COURTESY to you". Courtesy? He's giving YOU a "courtesy" but you are REQUIRED to obey him????

Dammit, I wish I could go to the mediator with you. It's so much easier to defend someone else than it is to defend yourself.

You CAN get through it. Just remember to take the higher road at all times and preserve your dignity and you'll do just fine. Phony acts work in your favor in situations like this -- be the nice guy to his face. Don't give his family any ammo.
