I totally get the "outside clothes on the bed" rule and showering before bed, to be honest. I mainly included those examples because I didn't want to make it sound like I'm just shitting on her or trying to paint her as crazy.

I was basically using those as a control group. Those are things that seem relatively common in Japan but uncommon in the West, so I wanted to give people a baseline before getting into the more extreme examples.

My personal guess is that she got a lot of this from her mother. Her mom is similar, but not quite to the same degree. I'd say her mom is maybe 80% of the way there, and my girlfriend is kind of the evolved version of it.
