You know she's good at playing the psychological warfare games. Don't let her win. She's calling your bet. Meet her at the table to show you're not scared of her. Don't back down, play hardball. Take as much as you can. Don't be fair. It's time to be vicious.
She'll walk away from the mediation... but that's cool... that's what you want and what you're buying: time and respect. It's a gamble, and I'm sure it's worth it.
Just my opinion.
