Is some jealousy normal?

Yes. What matters is how strong it is and what you do with it.

Jealousy usually shows up when we sense that a relationship we value is under threat from someone else. It is most often talked about in romantic relationships, and it is part of the human experience everywhere.

Feeling a pang when your partner laughs with an attractive coworker doesn’t mean your relationship is in trouble. Jealousy becomes a problem when it disrupts daily life, hurts your partner, or starts to feel more controlling than controllable.

Social media, likes and phones

More information can mean more worry.

Social media lets us see who our partner follows, likes and talks to. In a study of 308 students, more time on Facebook predicted more Facebook-related jealousy, even after accounting for personality and relationship factors.

Researchers suggested a feedback loop. Seeing something ambiguous leads to more searching, which turns up more things to worry about.

Jealousy or control? Knowing the line

Feelings are human. Controlling someone is not okay.

Even one or two of these behaviors is a red flag that abuse may be present. Warning signs can start small and grow over time.

When you’re the jealous one

Steps to calm the feeling and talk about it kindly.

It can feel embarrassing to admit jealousy. Treating it as information, rather than proof of something, gives you room to respond in a way you’re proud of.

When jealousy hits

  1. Pause before you act. Put the phone down if you need to.
  2. Breathe slowly and let your body settle.
  3. Name the feeling and the fear: “I’m scared they’ll leave.”
  4. Check the facts: what do I actually know?
  5. Ask what you need, and plan to share it calmly later.
🤲 Live with some uncertaintyNo amount of checking gives total certainty.

We can’t know or control what someone else thinks or feels. Accepting some uncertainty is part of easing jealousy.

Self-compassion means treating yourself with the kindness you’d offer a friend who is struggling. Shame tends to make jealousy hide and grow, while kindness makes it easier to face.

When your partner is jealous

  • “What would help you feel secure when I’m out with friends?”

  • A partner checks up on you, controls you or makes you afraid
  • Arguments about jealousy keep coming back
  • You can’t stop checking a partner’s phone or accounts
  • You feel hopeless or have thoughts of not wanting to be here
