W said its over - Said I can't change her mind

[Duds3]

"I filed for divorce. You can either go in the next couple of days and sign. If you
don't go sign then they will have to serve you work. It will be less embarassing if you just go sign.
You need to get tv water and electric out of my name. Please put my Taurus key in
mailbox and I will put your car key and apt key in there for you. At the end of the
week I will take my name off joint acct and stop using it."

Received this email from my W last night. What exactly should my next steps be? Need help from any and everyone????

I'm in a state of shock.
