So why didn't she pack up....did you talk her down or did she lose her head of steam and just forget. Or could it have to do with being jettisoned? you win by default.... lucky you. I think it could be bluff calling time.
Good news is you past the test or didn't get caught in the trap unfortunately the bad news is she just destroyed the last bit of trust you had. I'm with Atumnaltone on this.... her mess let her figure it out and fix it. I'd start protecting yourself and the kids.
