Green flags & red flags in relationships
Love should feel safe, steady and kind. Learning the signs helps you trust what you already feel.
By the numbers
What research says about healthy habits, and how common harm is.
Green flags
Red flags (U.S.)
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.

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.
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?
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
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.

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.”
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.
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.
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.
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.
Read more
Healthy partners can be honest and still have some privacy. Wanting a private space is not the same as hiding something.
Read more
Being honest with each other is part of trust. Over time, you learn you can rely on what they tell you.
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.
Read more
Accusing a partner of cheating without reason, or refusing to believe what they say, is a sign of an unhealthy relationship.
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.
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.
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.
Read more
Healthy partners talk about what they are and aren’t comfortable with, and respect each other’s limits.
Read more
Trying to control what you wear, how you spend money, or whether you go to work or school are forms of control.
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.
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.
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.
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.
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.
Read more
Extreme jealousy, insecurity and possessiveness are warning signs of abuse.
Read more
Getting irritated, pressuring you to drop friends, or going cold when you want time with others is a significant red flag.
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.
Read more
Healthy early attention feels comfortable and matches the pace you both want. Love bombing often feels forced, rushed or unwanted.
Read more
Thoughtful gifts and frequent texting can be normal. Watch for strings attached, like a gift paired with a demand.
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.
Read more
Constant calls, texts or messages, especially with an aggressive tone, go beyond normal early dating.
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.
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.
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.
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.
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.
Read more
Feeling nervous, afraid or unable to disagree with a partner is a sign that something is wrong.
What to do when you see a red flag
Pause, notice, talk it through, and keep yourself safe.
Steps that may help
- Pause. You don’t have to decide anything right away.
- Notice how you feel in your body and mind around this person.
- Write down what happened, just the facts.
- Talk to someone you trust for an outside view.
- If it feels safe, name the behaviour calmly and say what you need.
- Watch what they do next: listen and change, or blame and repeat?
- Decide what you want: talk more, slow down, step back or leave.
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.”
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.
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?
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.
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.”
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.
