I have always loved living in housefuls of family or de facto family. It feels like the most natural state of affairs. I wonder if that’s what a tribe feels like in some remote village. The closeness of family ends up a comfort.
Then again, this is the honeymoon phase. We’ll see how it shakes out. As with all human relationships, there will be ups and downs. With good communication and good boundaries any conflict or trouble can be worked through.
