Just as there are many different forms a polyamorous relationship can take, there are many different reasons people choose polyamory. We’re not always conscious of the reasons we do things, and sometimes we even make up reasons which have little to do with our real motivations. I’m not saying that we intentionally lie to ourselves, or to others. Rather, we find ourselves doing something and then make up a story to explain it. So it's not surprising that people are sometimes in dark about why they're choosing polyamory.
