What is jealousy?
A fear of losing someone or something important to someone else.
Jealousy is a mix of thoughts, feelings and actions that shows up when we sense a threat to a relationship we value. Usually there is a third person involved, and the threat can be real or imagined.
Everyone feels jealous sometimes. It can come up with partners, friends, brothers and sisters, family or coworkers. It has been described as part of the human experience across cultures.

Researchers see jealousy as a defensive reaction that may help people protect valued relationships. In studies of friendship, jealousy was stronger when the friendship mattered more.

Jealousy or envy? How they differ
Fear of losing what you have vs wanting what someone else has.
People often use the two words to mean the same thing, but researchers see real differences. Envy tends to come with feeling “less than”, longing and resentment. Jealousy tends to come with fear of loss, distrust, anxiety and anger.
In the same research, jealousy almost always came with some envy of the rival, but envy often happened with no jealousy at all.

Jealousy involves three people: you, someone you care about, and a person who seems to threaten that bond. Think of a partner texting an ex, or a best friend spending every lunch with someone new.

Envy is the painful feeling caused by someone else’s good fortune. It involves two people: you and the person who has the job, home, body or life you want.

Studies in the Netherlands, the U.S. and Spain found two different experiences of envy. “Benign” envy made people want to improve their own situation. “Malicious” envy made people want to bring the other person down.
Feeling envy is not a choice. What you do with it is where you have power.
Where jealousy shows up
Partners, friends, siblings, work and family.
Jealousy can show up in any close relationship. It often appears when someone threatens something important to you, like a relationship, your place in a group or your sense of being special to someone.

In your body, your thoughts and your actions.

Jealous thoughts can sound like

Jealousy can push us toward possessive behavior, like checking a phone, asking for constant updates or trying to limit who someone sees. These actions can hurt the other person and often make the jealousy grow.
Why do some people feel it more?
Past hurts, self-worth and early family life can all play a part.
Everyone has a different “jealousy volume”. Past relationships, how we see ourselves and what we learned growing up can all turn it up or down.

Extreme jealousy of a partner’s friends or time apart, and stopping them from seeing friends or family, are warning signs of abuse. Even one or two of these behaviors is a red flag.
Ways to cope in the moment
Pause, name it, and check the story before you act.
When jealousy flares, the urge to act right now can feel huge. Giving yourself a few minutes often changes what you decide to do.
A 5-step pause
- Breathe slowly for a minute and let your body settle.
- Name the feeling: jealous, scared, left out, sad, envious?
- Notice the story your mind is telling, and ask what you actually know.
- Ask what you need: reassurance, time together, a kind word to yourself?
- Choose one calm next step, or decide to wait and talk later.

Part of easing jealousy is accepting that we can’t fully know or control other people’s thoughts and feelings. Checking more rarely brings lasting calm.

Self-compassion means treating yourself with the kindness you would offer someone else who is struggling. It is a skill that can be learned.
Telling yourself you are better in some other way gives only short relief. Kindness toward your own self-doubt tends to work better.

Admitting envy or jealousy can feel threatening, so we often hide it, even from ourselves. Noticing unexplained irritation toward someone, or body signs like a racing heart, can be a clue.
Talking about jealousy
Share the feeling without blame.
Talking about jealousy calmly can bring you closer. Describe how you feel without blaming the other person, and try to choose a calm, neutral time and place.
Phrases you can borrow
- “I felt a bit left out when… Can we talk about it?”
- “I know this is my feeling to work on, and I’d love some reassurance.”
- “I noticed I got jealous, and I don’t want it to come between us.”
Read more
These usually make things worse
- Asking for passwords or checking devices
- Making someone choose between you and others
- Setting “tests” to see if they care
- Silent treatment instead of talking
Read more

Things that help

When and where to get help
Counselling helps, and you don’t need a crisis to reach out.
A counsellor or therapist can help you explore where your jealousy comes from and manage it day to day. Consider reaching out if jealousy is getting in the way of life, hurting someone you love, or feeling out of your control.
Reach out for support if…
- Jealous thoughts take up a lot of your day
- Someone is using jealousy to control you, or you feel unsafe
- You feel hopeless or have thoughts of not wanting to be here
- You keep checking, questioning or following someone
- Your relationships keep breaking down over jealousy
