I have never in my life imagined that someone might break up with another person for the sole reason that the person refused to poop in front of them. That is honestly wild to me, but I appreciate your perspective, thanks for sharing.
Similarly, married ten years and my wife and I have never seen each other use the bathroom. And barring dire emergencies I can't actually envision, we never will.
It's stories like these (and poor parenting I guess) that causes things like my cousin standing up to wipe for close to 30 years until his gf filled him in one day.
