How common harmful relationships are, and why they matter for health.

Partner abuse (U.S.)

1 in 3+women in the U.S. have experienced physical violence, sexual violence and/or stalking by an intimate partner in their lifetime
1 in 6+men in the U.S. have experienced the same
16 millionwomen, and about 11 million men, first experienced partner violence before age 18

Not every toxic relationship involves violence, so these numbers only show part of the picture. Feeling worn down, controlled or small in a relationship matters, even if no one has ever hit you.

What makes a relationship “toxic”?

An everyday word for a pattern that keeps hurting.

“Toxic” is an everyday word, not a medical diagnosis. People use it to describe a relationship that, over time, leaves you feeling more drained, anxious or small than supported. The key word is pattern: one bad day or one argument doesn’t make a relationship toxic.

Relationship experts often describe a spectrum. All relationships sit somewhere between healthy and abusive, with unhealthy in the middle, and a relationship can move along that line over time.

🌿 HealthyBuilt on equality and respect.
Read more

In a healthy relationship you make decisions together and can talk openly about problems. You enjoy time together and can also be happy apart.

It often includes

  • Equality
  • Good communication
  • Honesty
  • Respect
  • Trust without needing proof
The “Healthy relationships” guide in this app goes deeper into what healthy looks like.
🌫️ UnhealthyOne person tries to control more and more.
Read more

Unhealthy relationships are marked by attempts to control the other person. One person may make most of the decisions, pressure the other, or refuse to see how their actions hurt.

It can include

  • Breaks in communication
  • Dishonesty
  • Inconsiderate behaviour
  • Pressure
  • Problems that go unaddressed or turn into fights
  • Struggles for control
⛓️ AbusiveAn imbalance of power and control.
Read more

In an abusive relationship one person makes all the decisions, about friends, money, sex and even what is true. You may feel you can’t talk to anyone about what is really happening.

The National Domestic Violence Hotline is clear that abuse is always the responsibility of the person doing it, never the person on the receiving end.

If this sounds familiar, the “Domestic violence: the basics” and “Emotional abuse & gaslighting” guides can help you make sense of it.
“Toxic” describes a relationship pattern, not a whole person. People can behave in harmful ways for many reasons. Whatever the reason, you are allowed to protect yourself.

It’s not only partners

Toxic patterns can show up in families, friendships and at work.

We often talk about toxic relationships between partners, but the same patterns of control, put-downs and hot-and-cold treatment can happen in any close relationship where there is a power imbalance.

💔 Partners and exesDating, living together, married or broken up.
Read more

Toxic patterns with a partner can include jealousy, monitoring your phone, belittling you, cutting you off from people, sudden rage and pressure around sex. Some of these are warning signs of abuse.

For dating in particular, see “Narcissistic patterns in relationships” and “Dating & new relationships”.
🏠 Parents and familyHard to name when it has always been “normal”.
Read more

Someone who grew up around unhealthy behaviour may not recognise it as unhealthy, because it feels normal. That can make family patterns especially hard to see.

The “Dealing with difficult family” and “Low contact & no contact” guides cover family relationships in depth.
🤝 FriendsA friendship that leaves you feeling worse, again and again.
Read more

Friendships can become one-sided or controlling too. You might notice guilt-tripping, jealousy about your other friends, or always being the one who gives.

Questions to ask yourself

  • Can I say no without paying for it later?
  • Do I feel more tired or more tense after we spend time together?
  • Do they celebrate my good news?
  • Is the giving mostly one way?
💼 At workBosses, coworkers and workplace cultures.
Read more

Power imbalances at work, like a boss who controls your schedule or pay, can make harmful patterns harder to challenge.

The “Workplace bullying & harassment” guide covers your options at work.
⛪ Groups and leadersReligious, social or online groups.
Read more

Unhealthy attachments can also form with leaders of religious or social organisations, where one person holds a lot of power over others.

Warning signs can include being cut off from outside friends, being told what is true, and feeling afraid to question the group.

Signs a relationship is wearing you down

Patterns to notice, in the relationship and in yourself.

Signs of a toxic relationship are often about how you feel over time, not one dramatic moment. Notice patterns, and trust what keeps coming up for you.

🥚 Walking on eggshellsYou watch every word to avoid a reaction.
Read more

Walking on eggshells is a common sign in harmful relationships. You may plan conversations in advance, hide small things, or feel tense when you hear their key in the door.

🗯️ Constant criticismPut-downs, often in front of others.
Read more

Belittling someone often, especially in public, is a warning sign of abuse. Over time, repeated criticism can make you believe you are the problem.

🎛️ ControlDecisions, money, friends or time are decided for you.
Read more

One person dominating decisions, making money choices alone, or wanting to “own” the other person’s choices are signs of an unhealthy or abusive relationship.

🏝️ IsolationYou see less of the people who care about you.
Read more

Being cut off from friends or family, whether by rules, money or emotional pressure, is a warning sign. Isolation also makes it harder to get an outside view.

🎢 Hot and coldWonderful one day, cruel the next.
Read more

Unpredictable moods and swings between affection and hurt can keep you hooked, because the good moments feel like huge relief.

The “Trauma bonding” guide explains why this pull can be so strong.
🪞 Losing yourselfYou barely recognise who you’ve become.
Read more

Losing confidence and independence, and relying on the other person for approval, are signs that a relationship has become harmful.

You might notice

  • Doubting your own memory or judgment
  • Dropping hobbies or friends you used to love
  • Feeling you need their permission
  • Making excuses for them to others
This list is not a test or a diagnosis of you or anyone else. If several of these feel familiar, it may help to talk it through with someone you trust or a trained advocate.

Unhealthy or abusive? Why the difference matters

Conflict, control and safety.

Disagreements are a normal part of any relationship. What matters is how they are handled. In healthy relationships people talk problems through and listen. In unhealthy ones, problems turn into fights or get avoided.

Abuse is different. It is a pattern where one person uses many tactics at once to gain and keep power over the other. The Hotline points out that abuse doesn’t follow a predictable cycle, so you can’t reliably know when the next hurtful incident will happen.

🗣️ Mostly unhealthyBoth people struggle, and both can still speak up.
Read more

In an unhealthy relationship there may be poor communication, distrust or one person taking charge too often. You can usually still disagree without fear.

These patterns can sometimes change when both people want them to, often with outside help.

🔒 Signs of abuseFear, threats, control and isolation.
Read more

Signs of abuse include

  • Any kind of physical harm
  • Controlling money or decisions
  • Forcing or pressuring sex
  • Isolating you from family and friends
  • Threats, or talking in hurtful, demeaning ways
  • Using children to manipulate
If you are afraid of your partner or someone you live with, the National Domestic Violence Hotline can help you think it through, free and confidentially: 1-800-799-7233.
🧭 Why it mattersThe safest next step can be very different.
Read more

Advice that works for an unhealthy relationship, like an honest talk or setting a firm boundary, may not be safe when someone is abusive. With abuse, safety planning comes first.

The “Safety planning & leaving” guide walks through how to plan safely.

Why it’s so hard to see from the inside

And why people stay, without any shame.

From the outside, it can look obvious. From the inside, it rarely is. Harmful patterns usually build slowly, mixed in with good times, real love and shared history.

🐢 It happens graduallyEach step feels small, so the whole picture is hidden.
Read more

Harmful bonds often build gradually, starting with a lot of attention and affection before criticism and control creep in. Each new step can feel like a one-off.

☀️ The good times are realAnd they make the hard times confusing.
Read more

Many people describe a partner as wonderful most of the time. That genuine good behaviour is part of what makes leaving so hard.

❓ Self-doubt“Maybe I’m overreacting.”
Read more

Apologies, a “honeymoon” period after hurt, and gaslighting can all make people doubt how bad things really are.

The “Emotional abuse & gaslighting” guide explains how self-doubt can be created on purpose.
🏚️ It feels normalEspecially if you grew up with it.
Read more

Someone who grew up around unhealthy relationships may not recognise a partner’s behaviour as unhealthy.

The “Why we repeat toxic patterns” guide explores this gently.
🧳 Real-life reasons to stayLove, fear, money, children, culture and more.
Read more

People stay for many reasons

  • Children and family
  • Cultural, faith or community pressure
  • Disability or relying on them for care
  • Fear of what they might do
  • Love, and hope they’ll change back
  • No money or place to go
  • Shame, or feeling it is your fault
None of these reasons are weakness. They are real-life barriers, and they make sense.

How it affects your mind and body

Relationships shape our health, for better and worse.

A large review of about 50 years of research found that happier relationships go with better physical health. The link was roughly as strong as the link between health and diet or exercise.

Researchers think support may ease anxiety and sadness, while ongoing strain may feed negative thinking, low mood and unhealthy ways of coping. Happier couples also showed smaller jumps in heart rate and blood pressure during arguments.

People in harmful relationships often describe

  • Feeling anxious, on edge or numb
  • Headaches, stomach trouble or tiredness
  • Losing confidence and trust in their own judgment
  • Pulling away from friends and things they enjoy
  • Trouble sleeping or concentrating
Having some of these experiences doesn’t mean you have a mental health condition. Only a qualified professional can assess what’s going on for you. Please talk to your clinical provider or therapist.

Can a toxic relationship get better?

Sometimes, with effort from both people. Not when it’s abuse you’re waiting out.

Some unhealthy relationships do improve when both people see the problem, take responsibility and put in steady work, often with a counsellor’s help. Change that lasts is shown over months, not promised in a moment.

With abuse, the Hotline advises staying grounded in what someone does, not what they promise. Abusive patterns usually take a long time to change, if they change at all, and that change is entirely their responsibility.

✅ Signs change may be realConsistent, owned and pressure-free.
Read more

Look for

  • Changes that last when things get stressful
  • Owning what they did without blaming you
  • Respecting your “no”, your friends and your time
  • Getting help on their own, not just to win you back
  • You feel safer, not just hopeful
⚠️ Signs it may not bePromises, pressure and the same old pattern.
Read more

Watch for

  • Apologies mixed with blame
  • Big gestures instead of steady change
  • Pressure to forgive quickly or “move on”
  • The same hurt coming back once things calm down
🛋️ About couples counsellingHelpful for some patterns, not for abuse.
Read more

Couples counselling can help partners who both feel safe to speak honestly. Where there is abuse, it may not be safe to be open in front of the other person. Individual support or an advocate is usually the safer place to start.

The “Couples, family & group therapy” guide explains how couples counselling works.

Leaving safely, or stepping back

Ending, pausing or putting distance in a way that protects you.

If someone has been abusive, leaving can be the most dangerous time. Please plan with an advocate before you go. The National Domestic Violence Hotline (1-800-799-7233, or text START to 88788) can help, free and confidentially.

Not every toxic relationship is abusive, and not every one needs to end completely. Some people choose to end things. Others take a break, see someone less, or change what they share.

🗺️ Make a plan firstWho to call, where to go, what you’ll need.
Read more

A safety plan covers who to contact, where to go and what practical and emotional support you’ll need.

See the “Safety planning & leaving” guide for step-by-step help.
🔐 Close the easy doorsPasswords, location sharing and social media.
Read more

When it is safe, changing passwords and blocking contact can stop old patterns pulling you back in.

Small steps

  • Change shared passwords
  • Mute, unfollow or block
  • Turn off location sharing
  • Move old messages somewhere out of sight
📏 Stepping back without endingLess time, less sharing, clearer limits.
Read more

With some family members, friends or coworkers, you may choose distance instead of a full ending. That might mean shorter visits, keeping conversations to safe topics, or only meeting in groups.

The “Low contact & no contact” and “Setting boundaries & saying no” guides go deeper.
🧑‍🤝‍🧑 Tell your peopleYou don’t have to do it alone.
Read more

An outside view from a trusted friend, therapist or hotline can help you hold on to what you know when doubt creeps in.

🔁 If you go backIt doesn’t erase your progress.
Read more

The Hotline notes that people leaving abusive relationships return an average of seven times before they leave for good. Going back is common, and it is not a failure.

Every time you reach out, you learn more about what you need. Support will still be there next time.
Missing someone after you leave is normal. The “Breakups & heartbreak” guide can help with the weeks that follow.

How to support someone in a toxic relationship

Stay close, stay kind, and let them lead.

Watching someone you love get hurt is painful. The Hotline’s advice is to express concern without judgment, respect their decisions and encourage small steps. People who leave on their own terms are less likely to go back.

👂 Name what you’ve noticedSpecific, gentle and without blame.
Read more

Mention specific things you’ve seen, and let them know they are not alone.

You might say

  • “I’ve noticed you seem more tense lately. I’m here if you want to talk.”
  • “You don’t deserve to be spoken to like that.”
  • “Whatever you decide, I’m on your side.”
🚫 Avoid ultimatumsPressure can push them closer to the other person.
Read more

Telling someone what to do, or criticising the person they love, can make them feel they have to defend that person. Trust them to choose what feels right.

🪢 Keep the door openStay in touch, even if they go back.
Read more

Isolation is one of the ways harmful relationships take hold. Simply staying in their life can make a real difference.

🔋 Look after yourselfYou can’t fix this for them.
Read more

Supporting someone can wear you down too. Set your own limits and remember that the choice to leave is theirs.

If you think abuse is involved, the “Helping someone in an abusive relationship” guide has more ideas.

When and where to get help

Hotlines, therapy and crisis support.

It may help to talk to someone if
