Compersion is the positive feeling someone gets when their partner experiences pleasure, intimacy, or joy with another person. It is often described as the opposite of jealousy, though the two can coexist.
Compersion shows up most often in polyamorous and open relationships, where a partner's happiness with someone else can feel genuinely warm rather than threatening. People report it as a learned emotional response rather than an automatic one, and many find it grows with trust and open communication.
Worth knowing: Compersion is not a requirement in non-monogamous relationships, and pressure to feel it can mask real jealousy or discomfort that deserves honest conversation.
Also called: compersive, polyamory, metamour joy, frubble, reversed jealousy, empathetic joy
