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.

🧩 Three partsWhat you think, what you feel and what you do.

Jealousy can include

  • Actions, like checking, asking lots of questions or pulling away
  • Feelings, like fear, anger, sadness or hurt
  • Thoughts, like “They like her more than me” or “I’m going to lose them”

Noticing which part is loudest can help you choose what to work on first.

🛡️ A protective signalJealousy often points to something you care about.

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.

A signal is not an order. You can listen to what the feeling is telling you and still choose a calm, kind response.

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“I’m scared of losing you to them.”

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“I wish I had what they have.”
Read more

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.

Envy & comparing yourself to others goes deeper into envy, social media and comparison.
🌱 Two kinds of envyOne pushes you up. The other pulls others down.
Read more

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.

What jealousy feels like

In your body, your thoughts and your actions.

Intense jealousy can feel a lot like anxiety. It can affect sleep and appetite and bring a racing heart, sweating, tiredness and worried thoughts.

💓 In your bodyA racing heart, tight muscles, a knot in your stomach.
Read more

Common body signs

  • Feeling worn out
  • Racing heart
  • Sweating
  • Tense muscles
  • Trouble eating or sleeping

These are your body’s alarm system switching on. Slow breathing or a short walk can help it settle.

💭 In your thoughtsReplaying, comparing, imagining the worst.
Read more

Jealous thoughts can sound like

  • “Everyone likes them better.”
  • “I’ll be left behind.”
  • “They’re hiding something.”
  • “Why am I never enough?”

Thoughts that come with strong feelings can seem like facts. They are worth checking gently before acting on them.

🔁 In what you doChecking, questioning, sulking or pulling away.
Read more

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.

Jealousy can also hurt a partner, friend or relative who hasn’t done anything to cause it. Handling it with care protects them as well as you.

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.

🕰️ Past relationshipsOld hurts can shape what we expect now.
Read more

If you were cheated on, left out or let down before, it makes sense that your mind stays on watch. Reflecting on past experiences can show whether they are shaping what you expect today.

🪞 How you see yourselfLower self-worth can make jealousy louder.
Read more

In a study of young teens, those with lower self-worth reported more jealousy around their best friends. When we doubt we are worth choosing, other people can feel like bigger threats.

🏡 Growing upFeeling less loved than a sibling can leave a mark.
Read more

In a survey of 200 young adults, those who got unequal affection from parents compared with a sibling had more negative views of themselves and others. That was linked to more distress in their romantic relationships later.

📱 Lots of informationSeeing more can mean worrying more.
Read more

In a study of 308 students, spending more time on Facebook predicted more Facebook-related jealousy, even after accounting for personality and relationship factors.

When does jealousy become a problem?

When it feels more controlling than controllable.

Jealousy becomes a problem when it gets in the way of daily life, hurts someone you love, or feels more controlling than controllable.

🌀 Thoughts you can’t shakeUnwanted jealous thoughts and constant checking.
Read more

Some people have unwanted, upsetting jealous thoughts that feel out of step with what they believe, along with repeated checking of a partner. Clinicians sometimes call this obsessive jealousy.

Relationship OCD explains how doubts and checking can get stuck in a loop, and what helps.
🧱 Fixed beliefsBeing certain of cheating with no real evidence.
Read more

⛓️ Jealousy used to controlLimiting who someone sees is a red flag.
Read more

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.

Coercive control explains where jealousy turns into control.

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

  1. Breathe slowly for a minute and let your body settle.
  2. Name the feeling: jealous, scared, left out, sad, envious?
  3. Notice the story your mind is telling, and ask what you actually know.
  4. Ask what you need: reassurance, time together, a kind word to yourself?
  5. Choose one calm next step, or decide to wait and talk later.
🤲 Accept some uncertaintyYou can’t know or control what others think or feel.
Read more

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, not self-attackTalk to yourself like you would to a friend.
Read more

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.

🙋 Admit it to yourselfNaming the feeling takes away some of its power.
Read more

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.”
🚫 What to avoidAccusing, testing or demanding proof.
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
🗣️ Speaking up for a real needSometimes jealousy points to a fair request.
Read more

Jealousy can point to a real need, like more time together or feeling included. Asking for that clearly and kindly is healthy. Speaking up & assertiveness has more tips.

How to support someone who feels jealous

Setting boundaries & saying no has phrases you can use.
🧒 Supporting a childAccept the feeling, guide the action.
Read more

Children need to know that all their feelings are accepted, even the angry ones, while hurting others is not. One-on-one time can show a child that love is not limited.

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
