I was the opposite. My parents "stayed together" in that they lived in the same house but had separate bedrooms and lives. Most of the time when they were interacting it was some kind of power struggle. By age 13 my sibling became an addict and is to this day unable to sustain a job. I attribute it to the instability in the household growing up.

We're always going to see this through the lens of the experiences we grew up with.
