Green, yellow & red flags
A plain-language reference for recognising healthy, uncertain and unhealthy behaviour early.
Most people can name what hurt them only long after it has already hurt them. A flag is simply a piece of evidence, noticed early, about how a person treats you when nothing forces them to be kind.
Read behaviour, not potential. What someone says about who they are is information; what someone does repeatedly is the truth. One incident is a data point, a pattern is a decision.
Green does not mean guaranteed. Yellow does not mean leave. Red means your safety, dignity or reality is at stake, and it is not something you can fix by loving better.
Green flags — signs of health
Unglamorous, consistent behaviour. Green flags rarely feel like fireworks; they feel like your nervous system settling.
- Their words and their calendar agree
- Plans are made, kept and repeated. You do not have to interpret their interest; you can observe it.
- Curiosity about your inner life
- They ask questions and remember the answers. Attention is directed at who you are, not only at how you look or what you provide.
- A 'no' is received without punishment
- You decline something and the temperature of the relationship does not drop. No sulking, no withdrawal, no bargaining.
- Repair after friction
- Conflict ends in understanding rather than in a winner. They can say what they got wrong without a performance of self-hatred.
- They like your life, not just you
- Friends, family, work and rest are treated as part of you rather than as competition for their attention.
- Emotional weather is named, not thrown
- "I had a hard day and I am short-tempered" instead of an unexplained cold front you are expected to decode.
Yellow flags — slow down and look
Yellow is not a verdict, it is an instruction: gather more evidence, at normal speed, and see whether it resolves or hardens.
- Intensity far ahead of intimacy
- Declarations of love, future plans or exclusivity before they could plausibly know you. Speed can be sincerity — it can also be a way to skip your judgement.
- Every ex was 'crazy'
- A history with no shared responsibility usually means you are hearing the story you will one day be in.
- Inconsistent availability
- Warm for three days, distant for four, with no explanation. Unpredictability creates attachment; it is not the same as interest.
- Small disrespect, quickly laughed off
- Jokes about your body, your work or your intelligence, followed by "you are too sensitive". Watch whether it stops when you say it hurt.
- Vagueness about the basics
- Living situation, relationship status, work, weekends. Privacy is normal; a fog around ordinary facts is not.
- You are already editing yourself
- Rehearsing texts, softening opinions, hiding needs. Notice this early — it is information about the dynamic, not about your worth.
Red flags — stop and protect yourself
These are not compatibility problems and they are not yours to heal. Where safety is involved, planning matters more than confronting.
- Any physical force, or the threat of it
- Grabbing, blocking a door, punching a wall, driving dangerously to frighten you. Intimidation is violence even when nothing lands.
- Pressure or coercion around sex
- Persistence after a no, guilt, sulking, removing a condom, sex while you are asleep or intoxicated. Consent that is worn down is not consent.
- Rewriting what happened
- You are repeatedly told that events you clearly remember did not occur. Chronic reality-denial erodes your ability to trust yourself.
- Control of money, movement or contact
- Checking your phone, monitoring your location, restricting work or friendships, controlling spending. Coercive control is a pattern of confinement, not jealousy.
- Your leaving is treated as a threat
- Threats to harm you, themselves, your children, your pets or your reputation if you end things. Seek support before you act; this is the highest-risk moment.
- Contempt as a habit
- Humiliation in public or private, name-calling, mocking what you care about. Contempt predicts the end of a relationship better than conflict does.
How to read what you are seeing
Use time as your instrument
Anyone can perform well for six weeks. Meet across seasons, tiredness, illness, disagreement and their friends before you decide who they are.
Test with a small, honest 'no'
Decline something minor and watch what happens next. A person's response to a small boundary tells you how they will treat a large one.
Track the pattern, not the apology
Written down, three months of behaviour is very hard to argue with. Change is a different behaviour, sustained; not a better explanation.
Consult one person outside the story
Isolation makes bad treatment look normal. Someone who is not inside the relationship keeps your sense of scale intact.
If you need support
If you recognise red flags in your own relationship, you are not overreacting and it is not your fault. In the UK: National Domestic Abuse Helpline 0808 2000 247 (24h), or 999 in an emergency (press 55 if you cannot speak). In Portugal: APAV 116 006, Linha Nacional de Emergência Social 144, or 112 in an emergency.
