She is at it now.

Dude, by this time I would have said "Here's the deal, you start showing me some respect and including me in this.. Or Mr. Bull is over." If she leaves, she leaves.. It's almost as if it's that way anyway. You're the built in babysitter that's getting none of the fun. Which, I presume, is why the "bull" situation started in the first place. What turned into a 3 person situation has become a 2 person, them, and no you. That's horribly disrespectful to do that and then to act as if you don't have any ground to discuss it. No Sir, the entire operation would have come to a grinding halt at the fun factory.
Absolutely right,👍
