That sounds miserable.
No negations... do as I say or leave...
I may be weird in this aspect, but I don’t think I would ever take away control from my partner like that. I would lay out how I felt, and what I thought was best for our relationship. I would tell them how their actions affected my ability to trust them and their commitment to our partnership and the possible outcomes. I wouldn’t give them an ultimatum.
Adults don’t need strict rules as if they’re a children. Human emotions are way too complex for that. Ultimatums lead to resentment and/or lingering feelings. How would you ever trust that they were truly over it if you boxed them into a corner. That just an illusion imo. They need to come to the decision on their own.
But... like I said. I’m weird.
