...the start of something: papers?

With D filed, my vote is to stay mysterious.

If you choose to respond you could stick with your standard stance re "she can stay but you're not leaving".

If on a whim you choose to stay out late or not come home on any given night, it's no longer your burden to notify WW. If you notify her, you are kinda "giving her the day off" from experiencing the consequences of her actions.
