Good for you that you are so organized! That will give you confidence in your meeting.
FWIW, Jody (DB coach) advised me to use these negotiating sessions with H to supercharge my 180s. He will be surprised if you don't outwardly resist him (you need to resist in more sneaky ways). If you resist him in these conversations it will justify his decision to leave in his MLC mind. Use this as an opportunity to show him the old CW that he fell in love with. I know that you need to get answers for some of these issues now, but for issues that you DON"T need answered now, you can use these sessions as opportunities to put doubt in your H's mind. Also, when you get to the point of negotiating the specific terms of your D, if you can extend these sessions it will slow down the process.
For those issues that you and H disagree about, plan ways to make your points without being confrontational. For example, you can say "I'm confused about......" or try to make your point by asking a question instead of stating your opinion.
I DB'ed my a$$ off during our negotiating convos. H came to our home (where I was living) and I always dressed very nicely, with nice make-up, hair nicely done.........on a number of occasions I made fresh bread and had a fire in the fireplace. Several times we ended up reminiscing about some very happy times we'd had. My sweet cat, always came up to him and gave him lots of loving.
If you approach this will a cool, calm demeanor you can go a long way toward preventing this situation from spiraling out of control.
