Two parents, one brother, one sister, and (raise flame shield) one enby sibling in one house.
The brother moved out a few years ago to raise his daughters with his girlfriend. My sister used to live with her ex, but came home after a nasty attack at a hotel that lead to said ex being arrested.
As for me, I am working on finding a nice place to move out to later this year. It would had been a place for me and my former girlfriend (which we broke up today).
