Thanks all. The thing about saying I'll discuss with my L is that she actually hasn't written down anything concrete other than saying, in a ranting way, I'm doing you a favor to split the house this way. And I don't disagree much about that, just the percentage is high. I was going to reply to ask her to put everything on paper, or I will show everything on paper as to what I want. But that might get her incensed even more and essentially show my hand.
Another option might be to validate, then just say when you are ready to negotiate, write down a proposal and let's take it from there.
