Some polyamorous people get jealous, some don’t. Just as some people in monogamous relationships get jealous and others don’t.
It is probably safe to say that jealousy does come up for most people at some point. The difference between polyamory and possessive monogamy, is that people who are polyamorous don’t consider jealousy as proof of love (“if you really loved me, you’d be jealous”). Instead they see jealousy as a difficult reaction that needs to be thought about, talked about, and dealt with in some way.
Being polyamorous doesn’t mean you can’t feel jealousy, nor does it mean you have to deal with jealousy on your own. In a polyamorous relationship you and your partner(s) will talk about what happens when one, some, or all of you feel jealous. It may be an indication that someone is feeling left out, and that can be addressed. It may be an indication that there isn’t enough communication, which can also be addressed.
It is very important for people in polyamorous relationships to be aware of their jealousy and not to minimize it or ignore it.
