Lots of strange interactions going on. Must be the Pluto-Uranus square.
Had one with my H when he was royally PO'd that I did not consult him when I gave our D14 permission to go to the Home Coming dance with a bunch of her girlfriends. Geez, this is a guy that hasn't bothered to even ask about her report cards since he left 3 years ago. I let him have a few truth darts and I don't regret it.
I admire how you're handling your sitch. It has to be extremely hard living with a MLCer.
I think your H's alien costume will do quite nicely for Halloween!
