I do not think compromise is in the MLC dictionary. Don't know the law in your state, but my lawyer advised me that the second hand value of even very nice furniture is very low (unless you have heirlooms) My xh wavered between wanting nothing to do with any of his possessions, which he put in writing, to wanting me to pay ludicrous amounts to him for them.
Remember Snodderly and her xh and the plastic egg? We are not talking reason, consistency or fairness here. If it is MLC, which is sounds like, he will likely want something different tomorrow.
My xh has already made two attempts to revisit our original divorce settlement, concluded in January 2011, despite the Judge telling us both that without exceptional circumstances, this was the final settlement and could not be revisited.
The best you can do is not get sucked into it, and ask him for a list of what he wants as a basis for negotiation. The chances are he will lose interest in the game when it ceases to be 'fun' for him. For some reason they want to engage (think 'strokes', in Transactional Analysis terms) even if it is to wrangle. Disengage from the dance as soon as you spot it coming. It isn't even a zero sum game, but a lose/lose one.
