Jealousy in a relationship: when it’s normal and when it becomes control

Some jealousy in a relationship is normal. You feel a pang when your partner can’t stop talking about a new coworker, or when an old text from an ex pops up. It turns into a problem when the feeling becomes surveillance: going through their phone, tracking their location, telling them which friends they can see. Here’s how to tell the two apart, where jealousy comes from, and how to talk about it, whether you’re the jealous one or on the receiving end.

Normal, healthy jealousy is a feeling. It stings, and talking about it helps. Sometimes it comes from your own insecurity, sometimes from something real, like a broken promise. Either way, the person feeling it says so instead of acting on it: “It got to me when you were laughing so much with him. Can we talk about it?”

Unhealthy, controlling jealousy doesn’t stay inside. It turns into actions and rules for the other person:

• checking their phone, reading their texts, or demanding their passwords
• tracking their location, or putting an app on their phone without telling them
• texting and calling all day to find out where they are and who they’re with
• telling them who they can follow online or which friends they can see
• making them feel guilty: “If you loved me, you wouldn’t go to that party.”

You can feel intense jealousy without doing any of this. The line gets crossed when, instead of talking about the feeling, one person starts limiting the other’s freedom.

Underneath jealousy there’s often a fear of losing the person you love. In a 1997 study, psychologists Don Sharpsteen and Lee Kirkpatrick described romantic jealousy as partly a reaction to a threat to the attachment bond, the bond that makes us look for closeness and safety with a partner.

They also found that people handled jealousy differently depending on their attachment style. People who were anxious in relationships were more likely to hold their anger in. Avoidant people were more likely to direct their anger and blame at the rival. Secure people were more likely to tell their partner they were angry and work to keep the relationship going.

A year later, communication researcher Laura Guerrero surveyed 144 people in long-term relationships. Those who had a more negative view of themselves reported more jealous thoughts. People who were preoccupied with their relationships, always worried their partner might pull away, reported checking up on their partner more.

These studies describe trends in groups of people. They can’t tell you what’s going on in your relationship, and an online quiz can’t diagnose your attachment style either. If you want to understand your own patterns, a therapist can help.

Notice what set it off. Was it something specific, like a text, a late night, or a name that keeps coming up? Or was it a vague feeling? Writing it down helps you separate what you know from what you fear.

Talk about yourself, not them. “You’re always talking to her” puts your partner on the defensive. “When you mentioned her for the third time this week, I got scared I mattered less to you” gives them something to answer.

Don’t snoop. Going through their phone doesn’t settle the doubt. If you find nothing, the doubt can come back. If you find something, it’s hard to bring it up without admitting you snooped. Either way, you’ve broken their trust.

Ask for what you need. A text when they’re running late, meeting their new coworkers, a night together each week: those are requests, and a request leaves room for them to say no. Wanting to know where they are at all times is something else.

If your jealousy scares you, take it seriously. Maybe you catch yourself checking, forbidding, or threatening, or you suspect the jealousy has more to do with your past or your self-esteem than with your partner. Seeing a therapist on your own can help you sort that out.

If your partner is jealous but takes no for an answer without punishing you, you can reassure them without giving up your freedom. If you’re afraid of how they’ll react, skip to the section on abuse below.

• Listen for the fear under the accusation. Asking “Are you worried I’m pulling away?” can open more than a point-by-point defense. You can still correct what isn’t true, and you don’t have to take the blame.
• Share what feels normal to share. Telling them who you’re having dinner with, or introducing them to your friends, can take the edge off.
• Stick to your boundaries. Reassuring them doesn’t mean reporting to them. You can say no to handing over passwords, sharing your location, or dropping a friend.
• Watch whether it’s getting worse. If you start avoiding certain people, deleting texts to avoid a scene, or watching everything you say, that’s a sign of control. Read the section on abuse below.

• Talk when you’re both calm. Not when their phone buzzes, and not at 1 a.m. after a night out. Pick a quiet time and put your phones away.
• Say what’s OK for each of you. Lunch with an ex, liking photos, going out without each other: what seems fine to one of you may not be fine to the other. It’s better to know than to guess. This is about what you both agree to, not rules one of you sets for the other.
• Reassure each other in small ways. A text during the day, a compliment, time together. Small things won’t fix everything, but they help keep trust alive.
• Go back to what hurt. If the jealousy grew out of a past betrayal, talking about what happened is part of rebuilding trust, along with keeping your word over time. Our story on how to rebuild trust follows one couple through that. If you live apart, distance adds its own worries; see our guide to long-distance relationships.

At a calm moment, not in the middle of a fight, and only if you feel safe having this talk:

1. What usually sets off your jealousy: something I do, or someone around us?
2. How do you think my jealousy shows?
3. What helps you feel better when you have doubts?
4. What feels OK to you with an ex, a coworker, or a friend?
5. Is there something I do that worries you that you’ve never brought up?
6. What could we try this month to trust each other more?

The National Domestic Violence Hotline lists “acting jealous or possessive and refusing to trust you” as a form of emotional abuse. Its list also includes isolating you from family and friends and monitoring where you go. Online, it includes looking through your phone, insisting on your passwords, telling you who you can be friends with on social media, and using spyware or GPS to track you. Saying “it’s because I love you” doesn’t change what these things are.

If this sounds familiar, or you’re afraid of how your partner will react, don’t try to settle it in a talk with your partner. Get support on your own: you can call the Hotline at 1⁠-⁠800⁠-⁠799⁠-⁠7233, text START to 88788, or chat at thehotline.org. It’s free and confidential. The Hotline warns that internet use can be monitored; if you’re worried about that, call instead. In an emergency, call 911.

If jealousy keeps coming back no matter what you try, if it’s tied to an affair you can’t get past, or if you can’t talk about it without hurting each other, a couples therapist can help. Our guide to couples therapy explains who provides it and what it costs.

If there’s control or abuse, couples therapy isn’t the right place to start. The Hotline says it doesn’t encourage anyone in an abusive relationship to go to counseling with their partner, because “abuse is not a relationship problem.” Reach out to the Hotline first.

On Venna, you and your partner have a one-hour voice call with another couple who’s going through something similar, or has been through it. You pick a topic, like trust. The app asks the questions and gives each of you a turn. Nobody uses real names, and the session only happens if all four of you agree. Couples share what they’ve been through instead of giving advice. Nothing is recorded unless all four of you choose a recorded session with an experienced couple, and no AI listens.

Venna isn’t therapy, and it isn’t for control or abuse. If you’re dealing with abuse, call the National Domestic Violence Hotline at 1⁠-⁠800⁠-⁠799⁠-⁠7233 or text START to 88788. If you’re in crisis or thinking about suicide, call or text 988. In an emergency, call 911.
