My thoughts were similar to DnJ. Unless you want to meet to wrap up finances, then I wouldn't be so agreeable to meet and do all of the work for him. In my experience, I jump through hoops trying to give mine what he wants, and then he does absolutely nothing when it reaches a point that the ball is in his court.
I wouldn't agree to anything on the spot. I would go with a blank pad and listen to what he has to say and what he has to propose. Since you've done the work at the back end, you know what your needs are and you can ask questions to help move him along (did you factor in who would pay for the kids' summer camp, or what if my car breaks down, etc.).
Also, keep in mind that what the parties are dealing with in the interim often sets the stage for what a court later sees as what is needed (e.g., you've been getting by on $2k a month, why do you need $4k now?). So if you were to agree to less now, thinking you'll keep him happier, you could be hurting yourself later if there is a court determination on this stuff. Niceing them back doesn't work.
Like DnJ says, don't agree to anything without speaking with an attorney about what the financial picture would look like for you in divorce.
