Relationship red flags: how to recognise warning signs in your relationship
Updated: 3 hours ago
Most people have a moment, somewhere in a relationship, where something doesn’t feel quite right. Learning to notice that feeling, and treat it seriously, is one is the most productive things you can do for your own wellbeing. This guide from Online Psychologists Australia walks through what relationship red flags are, what to watch out for, and what to do once you’ve spotted one.
What are relationship red flags?
A relationship red flag is a pattern of behaviour, that signals a relationship may not be healthy, safe, or sustainable in its current form. Some are small and easy to dismiss at first, such as a partner who regularly checks your phone and brushes it off as “just curious”, or when you try to build in boundaries such as asking “please don’t check my phone” and they dismiss your needs.
Others are more serious in nature, such as open control or aggression. Recognising red flags early is important, as relationship patterns tend to become more entrenched over time.
Why do people miss red flags?
Red flags get missed for understandable reasons. Early optimism makes it easy to explain away behaviour that may otherwise cause concern in someone else’s relationship. Sometimes, a partner’s poor behaviour can be explained due to their mood or other life stressors. Attachment to a partner, especially once real history has been established, can make leaving or even questioning the relationship feel harder than staying.
Some people simply haven’t had the chance to learn what a healthy relationship looks like, particularly if controlling or critical behaviour was normal in a previous relationship, or within their own family dynamic. None of this is a personal failing. It’s part of why an outside perspective, whether from a trusted friend or a psychologist, can be so valuable.
Common relationship red flags to be aware of
When trying to examine if a person’s behaviour is a “red flag”, you want to look at patterns. Some patterns show up more often than others. The most common relationship red flags include patterns of:
Controlling behaviour
A lack of open communication
Ongoing disrespect or criticism
Dishonesty
Jealousy and possessiveness
Emotional unavailability
Avoidance of commitment
Gaslighting and manipulation
No item on this list automatically defines a relationship. But a pattern of them, especially one that leaves you feeling smaller, anxious, or unsure of your own judgement, is worth taking seriously.
Are red flags ever "fixable"?
Some red flags can improve with honest communication, self-awareness, and professional support. Poor communication habits or unresolved anger, for example, often shift once a partner is willing to work on them. Others don’t resolve through patience alone, particularly anything involving control, manipulation, or aggression.
The impact of ignoring relationship red flags
Red flags that go unaddressed rarely resolve on their own. Left unspoken, they tend to show up as ongoing emotional distress, a general sense of unhappiness that’s hard to pin down, or a gradual erosion of self-esteem as you quietly adjust your own expectations.
In more serious cases, ignored red flags can escalate into abuse. If you ever feel unsafe in your relationship, urgent support is available through 1800RESPECT on 1800 737 732.
Self-assessment: how to spot red flags in your own relationship
Spotting red flags in your own relationship is often harder than spotting them in someone else’s. Our Red Flag Radar is a free guide designed by psychologists to help you reflect honestly on your relationship.
It covers how controlling or gaslighting can show up, why trauma bonding makes it hard to leave an unhealthy relationship, and how to start setting boundaries and reconnecting with your own sense of self. This tool isn’t designed to diagnose the state of your relationship. It’s about giving yourself an honest, structured opportunity to check in.
What to do if you notice red flags
If something you’ve read here resonates, start with an open, calm conversation with your partner about what you’ve noticed. Decide whether you have been triggered due to needing to look after your own mood or set of underlying triggers, or if this is a boundary violation issue. Set boundaries around behaviour that isn’t okay with you and hold true to your boundaries.
Boundaries are not rules on someone else’s behaviour; rather, they are limits on what you will and won’t accept. Boundaries are the expectations you have and hold others to about how you will be treated. Talk to a trusted friend or family member too, since an outside perspective often sees things clearly that we can’t see from the inside.
If the pattern continues, or feels bigger than a single conversation can fix, relationship counselling or couples counselling with a qualified psychologist can help you work through it together, or on your own if that feels like the safer option.
Frequently Asked Questions
What are the biggest red flags in relationships?
Controlling behaviour, gaslighting, and unresolved aggression are generally considered the most serious, since they tend to affect your safety and sense of self most directly.
Are some red flags more serious than others?
Yes. Habits like poor communication sit differently from patterns involving control, manipulation, or aggression, which are far less likely to resolve without significant change from the other person.
How soon do red flags typically show up?
Some appear early, within the first few months. Others only surface once a relationship becomes more serious or established. Trust your reaction, even if a red flag shows up later than you expected.
Can red flags be changed?
Sometimes, particularly with genuine accountability and professional support like couples counselling. Other patterns, especially those involving control or safety, need to be taken seriously in their own right rather than treated as simply something to work through.
