In American culture, monogamy isn’t the only norm when it comes to relationships; it’s expected that everyone wants to and should be part of a couple. The fact of the matter is that some people who identify as non-monogamous or polyamorous prefer not to be in a “partnered” relationship, however they define that for themselves. In general, people who practice solo polyamory may date and have non-primary partners, but they don’t want to co-habitate, mingle finances and resources, raise children, or make important life decisions with a partner.
