Almost all divorces get settled out of court and I betchya anything he is just trying to manipulate you and scare you and he probably wants a trial even less than you do.
The guy is a nut job and so naturally he is doing nutty, stupid stuff.
I wouldn't worry about this too much and please, don't give into him. It may be a relief now but 2 years down the road you will be kicking yourself for giving in.
Do you have a good lawyer? If not, get one please. It can make the world of difference and remember, this is business.
Sorry he's being such an assclown sweetie. Oy! These guys!
