" It's possible to be single and poly. It's possible to have only one partner and be poly. If your intention is to remain open to the possibility of multiple romantic relationships, you are polyamorous regardless of your current relationship status. Indeed, if polyamory is part of your identity (for some people, it is; for others, it isn't), you might be in a monogamous relationship and still be poly. "
