WR, At this time, I would not cancel the court date. You've got plenty of time to do this. Your h is starting to panic because the date is only a week away and yes, he's heard from his lawyer and knows that he's caught between a rock and hard place. He's hoping to change your mind and bide some time to get things done his way. Trust me, when he made the comment about being fair, he certainly wasn't talking about you doing so. He's projecting on to you about himself and the situation...don't take that bit of bait. I heard those exact same words from my xh and I just laughed when he said them to me because nothing he did was fair at all.
I have a feeling he's not going to want to discuss this over the phone because he can't pressure you as much that way. He's going to want to sit down and talk to you about it and Wonka is absolutely right...do it in a very public place and he's going to want answers right then and there and if you don't agree, he's going to possibly get ugly and say all sorts of things. Be prepared for the worse and let's hope for the best. Be sure to have your car near by just in case you need to walk away. Just remember, you have the luxury of cutting the conversation short whenever you feel uncomfortable or it escalates to the point of getting close to an argument.
Yes, your h does think that everything will be figured out in a couple of hours and you'll be so happy to get it over and done with because it will be saving money in court fees. Don't forget, he's living in la la land and that's what they do there, i.e., flit all around and thing everything stops on a dime for them, i.e., the world revolves around them.
Whatever you do, do not agree to anything verbally or in writing. Tell him that you need to think about it and will get back to him. After that discussion, you will need to have a chat w/your lawyer to see her advice.
Stay as calm as you can. Keep your voice even and speak slowly and state specifics and stick to the issues at hand. This is going to be tough, but you will need to leave your emotions at the door for this meeting. I know you can handle this.
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.
