If it were me, I would respond with a simple "No, I don't agree with your settlement offer." And I would send it TOMORROW after his deadline, not today. How dare he try to bully you into agreeing to something that important without giving you time to think about it or even make a counter offer. if he wants to keep it out of the courts, he needs to loose the "It's my way or the highway" attitude and work towards an agreement with you, not try to dictate one. Glad you're standing your ground. Don't let him push you around.
