So if I call atty in the morning, do I give W the heads up?
No. Your email (with a specific deadline), was the heads-up. She blew it off.
Time for the consequences to kick in.
I'm sorry, Tar -- I know you wanted her to have some sudden "epiphany" here but sometimes it takes the shock of being served divorce papers for them to turn around (it did for my wife). Others NEVER turn around.
As they often say around here, "this is HER journey." All you can do is keep and enforce your own healthy boundaries now, and pray for her.
