My W would show similar behavior after she crossed lines, the kids said something, or such, through this since she worked through the "anger (aka, spew) stage". I would just dim a wee bit...see where this goes...let her lead (but DO see your L a least about rights and such, if you haven't already).
I got BD#3 end of April, told her I would be the bad guy and file end of May, and she's still in house and nothing filed to my knowledge, and no increase in "extra curricular" activities that I can see...
I agree with Chuck, reality was delivered by another hand besides yours. If you W is like mine at all, she may be mentally toying with the D idea, playing it out, trying it on, maybe doing the math...
