My Boyfriend Has Two Girlfriends. Should I Be His Third?

I grew up in a polyamorist home, my father had two live in 'wives' the entire course of my childhood and they are still together.

I assume it was like most families. A total mess with phases marked by warring jealous women. While one is my mother, I was raised by both and treated differently by both.

Good times, I wish it on everyone.
