Ok- Just got back. STBX agreed to everything. He will pay a reasonable amount of child support (quite a bit more than the state would have required him to pay but apparently less than he was expecting) Finances will be tight for me for a year or two but I should be ok.
He agreed that I would have sole physical custody and he will have visitation. He did hesitate a bit at that one - but ultimately agreed. I really wasn't offering him any less time than he asked for - this arrangement just gives me a little more flexibility (particularly during the school year).
There was one terse moment. I said we would need to go to co parent counseling, but that after the revelation about him living with OW, I needed more time before I spent that much time with him. He immediately bristled at that one and got hostile.
I had him initial each point - I will feel much more relieved when it is in a legally binding divorce decree.
