In my case, my xh was okay until I had a draft separation agreement drawn up (per his instructions). Once he got the draft separation papers, he became a very angry man and stayed that way for about 5 years. He realized that he wasn't going to get everything his way. He thought he could dictate what he wanted and it would happen. He should have known that I wasn't going to roll over and give him whatever he wanted. He should have known that I had worked w/lawyers and used the law library whenever I wanted to look things up. I guess he "assumed" that I loved him enough to give him everything...he soon found out it didn't happen.
As Peace pointed out, the divorce is a business deal. It is dealing w/a contract that has been broken and now the parties involved have to come to the table and separate assets, etc. No one wins when this type of action takes place. Lawyers and judges see this behavior more and more. Some lawyers will say and do anything to keep the MLCer coming back and racking up billable hours. I hope your lawyer realizes that you mean business and not tolerate unnecessary expenses along the way.
Yes, it may get ugly. Strap yourself in and be prepared for a bumpy ride.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
