Thanks all. I'm sitting on an email response for another two days while I think about how to reply. Mentioning L does seem like escalation, but I guess she is giving me no choice. I like the line: "Write down how to split our assets, and I'll discuss with a L."
Compared to where I was two weeks ago, I certainly feel indifferent. And she can feel it. She's hardly engaged and hasn't escalated anything. And when she complains about something, it's respectful. It's actually quite nice, the way it should be.
To SteveLW's question, I can wait it out for a while. Two weeks ago, no I couldn't. But now, yes. We agreed to sell the house in alignment with kids end of school term. It needs to be 1 year after BD anyhow for a formal divorce.
