No need to respond to any of the prior debate if you dont want to. It will only put fuel on a fire that needs to be extinguished.
Good deal on the getting some movement towards clousure. There are many other financial things to negotiate - college, spousal/child support, tax credits/deductions, debts, asset division.
But as I said before, both L's and the system have done a crappy job by not getting the custody/parenting plan settled first.
I hope your STBXW gets plenty of time to speak in front of a judge. She will be her own worst enemy.
