By the numbers

What research says about healthy habits, and how common harm is.

Green flags

86%of the time, couples who were still married six years later “turned toward” each other’s small bids for attention
33%of the time, on average, for couples who later divorced
5 to 1the “magic ratio” of positive to negative moments during conflict seen in stable, happy couples

Red flags (U.S.)

~1 in 2women and men have experienced psychological aggression, like insults or control, by a partner in their lifetime
1 in 3+women and 1 in 6+ men have experienced physical violence, sexual violence and/or stalking by a partner
1 in 12high school students who dated experienced physical dating violence in the past year
Harm in relationships is common, and so is healthy love. Knowing the signs is not about being suspicious. It is about knowing what you deserve.

What green and red flags really mean

Patterns, not single moments, and behaviours, not labels.

A green flag is a behaviour that shows respect, trust and care. A red flag is a behaviour that shows disrespect or a wish to control. Experts describe all relationships as sitting on a spectrum from healthy to abusive, with unhealthy in the middle.

Flags are about patterns. Everyone has bad days, says the wrong thing or gets jealous sometimes. What matters is what keeps happening, and what happens after a hurt: repair, or more of the same.

🟢 Green flagsSigns of respect, honesty and equality.
Read more

In a healthy relationship you talk openly about problems, value each other’s opinions and feelings, believe each other, make decisions together and respect each other’s time apart.

The “Healthy relationships” guide describes the healthy end of the spectrum in more depth.
🟡 Yellow flagsThings worth a calm conversation.
Read more

Some things are not dangerous, but they are worth talking about. Examples might be different ideas about money, a habit of going quiet in arguments, or a partner who is slow to text back.

With a yellow flag, the key question is how the other person responds when you raise it. Do they listen and try, or brush it off?

The “Talking about a yellow flag” worksheet can help you plan what to say.
🔴 Red flagsSigns of disrespect, control or danger.
Read more

Unhealthy and abusive relationships are marked by poor communication, disrespect, distrust, dishonesty, control, isolation, unfounded accusations, money control and sexual pressure.

Warning signs of abuse include

  • Any form of physical harm
  • Checking your phone, email or social media without permission
  • Explosive outbursts, temper or mood swings
  • Extreme jealousy or insecurity
  • Isolating you from friends or family
  • Possessiveness or controlling behaviour
  • Pressuring or forcing you to have sex
  • Putting you down often, especially in front of others
Flags describe behaviour, not a whole person. This guide is not a test for you or anyone else. It is a way to notice patterns and talk them through.

Respect vs. contempt

Being valued, even when you disagree.

Respect means your opinions, feelings and needs matter, and you have room to be yourself. It does not mean you always agree. Respect shows most clearly in how someone treats you when you disagree.

🟢 Complaints about a problem“I was scared when you were late and didn’t call.”
Read more

The Gottman Institute separates a complaint, which is about a specific problem, from criticism, which attacks someone’s character. Raising a complaint is healthy and normal.

Green flags sound like

  • “Can we talk about what happened last night?”
  • “I see it differently, but I hear you.”
  • “That’s my fault. Let me fix it.”
🔴 Attacks on who you are“You never think about anyone but yourself.”
Read more

Criticism turns a problem into a statement about your character. Over time, being told what kind of person you are can wear down how you see yourself.

The “Guilt-tripping, put-downs & character attacks: disrespect in relationships” guide goes deeper into this.
🔴 ContemptMocking, sneering, eye-rolling and name-calling.
Read more

Contempt says “I’m better than you.” It includes sarcasm, mockery, name-calling, hostile humour and eye-rolling. Gottman research calls contempt the number one predictor of divorce.

The antidote is a habit of fondness and appreciation, and describing your own feelings instead of attacking.

🔴 Public put-downsMaking you look small in front of others.
Read more

Putting you down often, especially in front of other people, is a warning sign of abuse. So is humiliating you in any way.

Everyone slips into criticism sometimes. The “Handling conflict & repair” guide covers how couples catch it and repair.

Trust & honesty vs. suspicion & secrets

Believing each other, and still having privacy.

Trust means you believe what each other says and don’t have to keep proving yourself. Honesty means you don’t lie to each other, but you can still keep some things private.

🟢 Privacy is respectedYour phone, diary and thoughts are yours.
Read more

Healthy partners can be honest and still have some privacy. Wanting a private space is not the same as hiding something.

🟢 Words match actionsThey do what they say they will.
Read more

Being honest with each other is part of trust. Over time, you learn you can rely on what they tell you.

🔴 Checking up and demanding proofSnooping, passwords and constant questions.
Read more

Checking your phone, email or social media without permission is a warning sign. So is demanding passwords or proof that you have not broken the relationship’s rules.

🔴 Accusations without reason“Who were you really with?”
Read more

Accusing a partner of cheating without reason, or refusing to believe what they say, is a sign of an unhealthy relationship.

🔴 Lies and rewritten factsLeaving things out, or denying what happened.
Read more

Lying, leaving out facts or blurring the truth is a red flag. When someone keeps denying things you clearly remember, it may be gaslighting.

See “Gaslighting: what it is and how to trust yourself again”.

Support vs. control

A partner who backs your choices, or one who makes them for you.

In a healthy relationship, you make decisions together and hold each other to the same standards. Both people have access to what they need. Control means one person’s wishes always come first.

🟢 Cheering you onYour goals, work and growth matter to them.
Read more

A supportive partner backs your work, study and goals and wants you to have what you need. Equality means both people have a real say.

🟢 Your “no” is acceptedThe first time, without sulking.
Read more

Healthy partners talk about what they are and aren’t comfortable with, and respect each other’s limits.

🔴 Decisions made for youWhat you wear, eat, spend or do.
Read more

Trying to control what you wear, how you spend money, or whether you go to work or school are forms of control.

🔴 Money controlOne person holds all the purse strings.
Read more

Making money decisions alone, or blocking a partner’s access to income or resources, is a sign of an unhealthy or abusive relationship.

🔴 Pressure around sexGuilt, pressure or force.
Read more

Using pressure or guilt to push someone into sexual activity or choices about having children is a red flag. Consent is always freely given, and you can say no at any time.

When control becomes a whole web of rules, threats and monitoring, it may be coercive control. The “Coercive control” guide explains this pattern.

Your own life vs. jealousy & isolation

Room for friends, family and time apart.

Healthy partners respect each other’s need for time and space apart. A little jealousy is human. Jealousy that leads to rules about who you can see is control.

🟢 Glad you have peopleThey like that you have friends and hobbies.
Read more

A partner who respects your other relationships is a green flag. Keeping your friendships and family ties strong is also one of the best protections you have.

🟢 Jealousy talked about, not acted out“I felt a bit left out. Can we talk?”
Read more

Feeling jealous sometimes is normal. A green flag is someone who owns the feeling and talks about it, instead of making rules for you or accusing you.

🔴 Extreme jealousyPossessive, insecure and accusing.
Read more

Extreme jealousy, insecurity and possessiveness are warning signs of abuse.

🔴 Wanting all your timeIrritation or sulking when you see others.
Read more

Getting irritated, pressuring you to drop friends, or going cold when you want time with others is a significant red flag.

🔴 Cutting you offFrom friends, family, money or community.
Read more

Isolating someone, whether physically, financially or emotionally, makes them easier to control. It also makes it harder to get an outside view.

Flags in early dating

Pace, consistency and respect in the first weeks and months.

Early on, it can be hard to tell intense affection from love bombing. love is respect describes love bombing as excessive attention, affection or gifts that push past your pace and your limits.

🟢 A pace that suits you bothAttention feels warm, not rushed.
Read more

Healthy early attention feels comfortable and matches the pace you both want. Love bombing often feels forced, rushed or unwanted.

🟢 Gifts with no stringsThoughtful, not a debt.
Read more

Thoughtful gifts and frequent texting can be normal. Watch for strings attached, like a gift paired with a demand.

🔴 “Soulmate” in week twoBig labels and promises, very fast.
Read more

Over-the-top compliments, calling you a soulmate or saying “I love you” within weeks can be signs of a bigger issue, especially if it makes you anxious.

🔴 Constant contactCalls and messages that feel like too much.
Read more

Constant calls, texts or messages, especially with an aggressive tone, go beyond normal early dating.

The “Dating & new relationships” guide covers dating apps, first-date safety, consent and ghosting.

Flags in long-term relationships

Everyday kindness, repair, and changes that creep in.

In long relationships, flags often show in small, everyday moments. Gottman researchers found that couples who stayed together turned toward each other’s small bids for attention 86% of the time, compared with 33% for couples who divorced.

🟢 Turning toward youNoticing your small bids for connection.
Read more

Gottman researchers define a bid as any attempt from one partner to another for attention, affirmation, affection or other positive connection.

A bid can be as small as sharing a thought or sighing after a long day. Responding warmly, even briefly, shows you are there.

🟢 Repair after fightsHard moments get fixed, not buried.
Read more

Healthy couples still have negative moments, but they repair them quickly. Stable couples have about five positive moments for every negative one during conflict.

🔴 Contempt creeping inEye-rolls and sarcasm becoming normal.
Read more

Contempt grows from long-simmering negative thoughts about a partner. Research links contemptuous couples with more colds and flu, as well as a higher risk of breaking up.

🔴 Rules that keep growingEach new limit on you feels small.
Read more

Control often builds slowly. Watch for a growing list of things you need permission for, or a partner who gets angry when you don’t do what they want.

🔴 Feeling afraid to disagreeWalking on eggshells.
Read more

Feeling nervous, afraid or unable to disagree with a partner is a sign that something is wrong.

The “Building stronger relationships” guide has small daily habits that grow green flags.

What to do when you see a red flag

Pause, notice, talk it through, and keep yourself safe.

If you feel afraid of someone, safety comes first. Talking it through with an advocate at the National Domestic Violence Hotline (1-800-799-7233, or text START to 88788) is free and confidential.

Steps that may help

  1. Pause. You don’t have to decide anything right away.
  2. Notice how you feel in your body and mind around this person.
  3. Write down what happened, just the facts.
  4. Talk to someone you trust for an outside view.
  5. If it feels safe, name the behaviour calmly and say what you need.
  6. Watch what they do next: listen and change, or blame and repeat?
  7. Decide what you want: talk more, slow down, step back or leave.
🗣️ Raising it, if it’s safeDescribe your feelings, not their character.
Read more

Talking openly about what feels uncomfortable, and saying what you are comfortable with, is a healthy step when you feel safe to do it.

You might say

  • “I felt hurt when you read my messages. I need my privacy respected.”
  • “I want to keep seeing my friends on weekends. That’s important to me.”
🛑 When talking isn’t safePlan with an advocate first.
Read more

If someone has been violent, threatening or very controlling, raising it directly may not be safe. An advocate can help you think through options and make a safety plan.

The “Safety planning & leaving” guide walks through this step by step.
🪞 Noticing your own red flagsEveryone can learn and change.
Read more

Hurtful behaviour can be hard to see when you are the one doing it. The Hotline says acknowledging you may be hurting a partner is the first step toward a healthier relationship.

Questions to ask yourself

  • Do I check where they are or read their messages?
  • Do I get angry when they don’t do what I want?
  • Do I struggle to calm down once I’m angry?
  • Do I yell, call them names or put them down?
  • Do I expect them to get my approval before seeing others?
The Hotline also takes calls from people worried about their own behaviour: 1-800-799-7233.
You don’t need a “good enough” reason to slow down or end a relationship that makes you uneasy. Your gut feeling is information.

How to support a friend who sees red flags

Listen, stay close, and let them lead.

If a friend’s partner worries you, staying in their life matters. Isolation is a key warning sign, so simply being there helps.

👂 Listen firstBelieve them and don’t rush to judge.
Read more

Let them talk without interrupting or telling them what to do. Reflect back what you hear.

You might say

  • “That sounds really hard.”
  • “You don’t deserve to be spoken to like that.”
  • “Whatever you decide, I’m here.”
🚫 Skip the ultimatumsPressure can push them away.
Read more

Criticising their partner or saying “leave or else” can make them defend the relationship. Gently name what you’ve noticed instead, and trust them to choose.
