What is Compersion?
Compersion: Compersion is the warm, happy feeling you get when a partner finds joy or pleasure with someone else, often used in polyamory and open relationships as the flip side of jealousy.
Also known as: Frubble.
Compersion is a word you will run into a lot in polyamory and open relationship spaces. It describes the feeling of genuine happiness you get watching a partner fall for someone new, have great sex with another partner, or come home glowing after a date that had nothing to do with you. Instead of feeling threatened, you feel glad. Some people describe it as being happy for your partner's happiness, even when you are not the one who caused it.
It is not a rule you have to follow and it is not proof that a relationship is healthy or unhealthy. Compersion is a feeling, and feelings show up on their own schedule. Some people in non monogamous relationships feel it often. Others feel it rarely, or only after working through jealousy first, or not at all, and still build relationships that work fine for them. Knowing the word gives you language for something that can feel confusing the first time it happens to you.
What Does Compersion Actually Mean
At its simplest, compersion is empathetic joy. You feel good because someone you care about feels good, even though you are not directly involved in the thing that made them happy. It gets used most often to describe the feeling a person has about a partner's other romantic or sexual relationships, but the concept can stretch further than that.
People sometimes feel small flashes of compersion outside of polyamory too. Being happy for a friend's new relationship, or feeling warm watching your partner enjoy time with an old friend, works on a similar emotional muscle. In non monogamous communities the word gets a sharper, more specific use because it names a feeling that jealousy often crowds out.
Compersion is not the absence of jealousy. Many people feel both at once, a little ache alongside real happiness for their partner. That mix is normal and does not mean you are doing polyamory wrong.
Where Does the Word Compersion Come From
Compersion is a coined word, not one you will find in older dictionaries. It came out of intentional communities experimenting with non monogamy, most commonly traced back to the Kerista Commune in San Francisco in the later part of the twentieth century, where members needed a word for the opposite of jealousy and did not think one existed yet.
From there it spread through polyamory writing and online forums in the 1990s and 2000s, picked up by authors and educators talking about ethical non monogamy. It stuck around because it fills a real gap. English has plenty of words for jealousy and envy but very few for feeling happy about someone else's good fortune, especially in a romantic context.
How Compersion Feels in Real Relationships
In practice, compersion can be quiet or intense. It might look like feeling pleased that your partner had a great first date, without needing details. It might be a rush of warmth hearing your partner laugh on the phone with someone new. For some people it can even be a little bit turned on by imagining a partner's pleasure with someone else, though that crosses into a different feeling for a lot of people and both reactions are completely normal.
Compersion often grows over time rather than arriving fully formed. New relationships, especially ones involving new relationship energy, can stir up insecurity even in people who generally feel compersion easily. It is common to feel compersion about one partner's other relationship and jealousy about another, depending on the people, the history, and what is going on in your own life that week.
It also is not owed to anyone. Nobody in an open relationship or polyamorous relationship is required to feel compersion, and pretending to feel it when you do not usually backfires. Naming the actual feeling, even when it is jealousy or something more mixed, tends to serve a relationship better than performing an emotion you have not reached yet.
How to Practice Compersion in Polyamory or Open Relationships
If compersion does not come naturally, there are ways to work toward it without forcing anything. Start small. Notice moments where you feel neutral or slightly positive about a partner's other connections, rather than jumping straight to the hardest situations.
Get curious about your jealousy instead of pushing it away. Jealousy usually points at something underneath it, a fear about being replaced, a need for more reassurance, a scheduling worry, or an old wound from a past relationship. Working through that root cause often clears space for compersion to show up on its own.
Give yourself credit for small wins. Feeling glad your partner had a nice time, even for a few seconds before other feelings crowd in, counts. Compersion tends to build with practice and with a partner who takes your feelings seriously, rather than through willpower alone.
Talking to Your Partner About Compersion
Compersion works best in relationships with honest communication, not in relationships where feelings get hidden to keep the peace. Tell your partner when you feel it. Hearing that you are happy for them, specifically, helps build trust and makes it easier for them to share their other relationships with you openly.
Be just as honest when you feel the opposite. A partner cannot support you through jealousy they do not know about. Framing it as information rather than a complaint, something like I felt a pang when you mentioned that date, can I tell you about it, keeps the conversation useful instead of accusatory.
Check in regularly rather than only during hard moments. Some couples and polycules set aside time to talk through how everyone is feeling about the relationship structure in general. That kind of ongoing conversation makes room for compersion to grow and gives jealousy somewhere safe to land when it shows up instead.
Is Compersion Something Everyone Can Feel
Compersion is not a skill everyone develops, and it is not a requirement for a healthy non monogamous relationship. Some people feel it easily and often. Others build satisfying polyamorous or open relationships while feeling little to no compersion, relying instead on solid communication, clear agreements, and simple tolerance of a partner's other relationships.
Some early research has found links between compersion and relationship satisfaction in non monogamous relationships, but this research is still new, limited in size, and mostly shows correlation rather than proof that compersion causes a relationship to be more stable or last longer. It is a real and well described feeling, but it is not a measurement of how good a relationship is. If you do not feel it, that does not mean you are failing at polyamory. If a lot of jealousy feels overwhelming or is affecting your wellbeing, talking to a therapist who has experience with non monogamous relationships can help more than trying to force a feeling that has not arrived yet.

Key Things to Know
- Compersion means feeling happy about a partner's other relationship, which gives polyamorous and open couples a word for a feeling monogamy rarely names.
- It is not required in non monogamy, so you do not need to feel it to be doing an open relationship or polyamory well.
- It can coexist with jealousy, so feeling both at once about the same situation is normal and not a sign something is wrong.
- Talking openly about both compersion and jealousy builds trust, which matters more for relationship health than which feeling shows up first.
- Some small studies have linked compersion to relationship satisfaction, but the research is still limited and does not prove it causes a relationship to succeed, so it is best treated as a feeling to notice, not a goal to chase.
