Let’s get one thing straight: every relationship hits a rough patch. Partners argue over whose turn it is to empty the dishwasher. Friendships go through seasons. Family dynamics get weird at Christmas. That’s just life. But a toxic relationship is something else entirely — it’s the kind that consistently leaves you feeling drained, anxious, or like you’ve somehow been cast as the villain in a story you didn’t sign up for.
According to the Australian Bureau of Statistics 2021–22 Personal Safety Survey, an estimated 4.2 million Australian adults — that’s 21% of us, or roughly one in five — have experienced violence, emotional abuse, or economic abuse by a partner. And that’s just the stuff people reported. The numbers for toxic (but not legally defined as abusive) relationships are almost certainly higher.
In America, research published in Medium by occupational therapist Christopher Zoboroski (2025) confirms that toxic relationships are linked to anxiety, depression, and even serious physical conditions like heart disease. So no, it’s not “just drama.” It’s a genuine health issue — and it’s time we treated it like one.
What Actually Makes a Toxic Relationship?
A toxic relationship isn’t simply one where two people don’t get along. It’s a pattern — repeated, consistent behaviour that chips away at one person’s wellbeing, confidence, or sense of reality. And before you ask: yes, it can happen in romantic partnerships, friendships, family relationships, and workplaces. Toxicity is an equal-opportunity problem.
Psychologist John Gottman, whose work is widely cited across American relationship research, identified four communication patterns that reliably signal relational toxicity: criticism, contempt, stonewalling, and defensiveness. He called them the Four Horsemen of relationship breakdown — and honestly, it tracks. If your partner rolls their eyes every time you speak, that’s not a quirk. That’s contempt, and research says it’s one of the strongest predictors of relationship failure.
Meanwhile, a 2025 study published in the journal Women’s Health by researchers at the University of Melbourne found that for most Australian survivors of abusive relationships, psychological abuse emerged before any physical or sexual abuse. In other words, it starts in the mind. By the time things escalate physically, the groundwork has already been laid through isolation, manipulation, and control.
Common red flags to watch for include:
- Constant criticism or contempt — nothing you do is ever good enough
- Gaslighting — your partner reframes reality until you genuinely doubt your own memory
- Isolation — being gradually cut off from friends and family (directly or through guilt)
- Walking on eggshells — constantly managing their moods at the expense of your own
- One-sided effort — you’re doing all the emotional heavy lifting, and you’re exhausted
- Intermittent reinforcement — periods of warmth and kindness interspersed with cruelty, which actually makes you more attached, not less
That last one is sneaky and worth dwelling on. A 2025 paper on toxic intimacy dynamics explains that intermittent reinforcement — when kindness and cruelty alternate — actually causes the recipient to become more strongly attached, not less. Your brain is essentially being trained like a slot machine. You keep pulling the lever because sometimes you win. That’s not love. That’s conditioning.
Why People Stay (And Why That’s Nobody’s Business But Theirs)
Here’s the thing people love to say from the outside: “Just leave.” Ah yes. Why didn’t they think of that? Two words that solve nothing and judge everything.
The reality is far more complex. Attachment theory — now backed by decades of psychological research — tells us that people who grew up in unstable or neglectful environments often develop anxious or avoidant attachment styles. These patterns make it significantly harder to leave toxic relationships, because the nervous system has literally been conditioned to associate love with instability.
A 2025 study published in Frontiers in Psychiatry found that childhood trauma directly shapes adult attachment patterns and emotional regulation — meaning the roots of toxic relationship cycles often stretch back long before the current relationship even started.
Other factors that keep people stuck include financial dependence, fear of retaliation, shared children, social or cultural pressure, and the very real hope that the person they fell for — the good version, the one who occasionally shows up — will become permanent. Spoiler: they won’t. But hope is a powerful thing, and it doesn’t make someone naive. It makes them human.
The 2025 Australian national survey on intimate partner violence prevalence, published in the Medical Journal of Australia, also highlighted that people with disability, those from LGBTQIA+ communities, and young adults aged 16–24 are particularly vulnerable — and often face additional structural barriers to leaving. Resources and support need to reflect that reality.
The Real Cost: What Toxic Relationships Do to Your Body and Brain
In case you needed more convincing that this is serious: toxic relationships don’t just hurt your feelings. They hurt your body.
Research shows that long-term exposure to toxic relationships increases stress hormones, weakens the immune system, and raises the risk of cardiovascular disease. A 2025 clinical insight report from American therapists in Pennsylvania noted that emotional abuse can actually rewire the brain — impacting memory, decision-making, and emotional regulation. This isn’t metaphor. This is neuroscience.
Studies cited by the Prime Behavioural Health research team found that individuals in emotionally detrimental relationships experience a 50% increase in symptoms of anxiety and depression. Meanwhile, the stress of toxic dynamics can disrupt sleep, heighten cortisol levels, and impair concentration — all things that compound over time and make it even harder to think clearly or take action.
The effects don’t end when the relationship does. Trust issues, emotional numbness, and difficulty forming secure new connections can linger long after you’ve walked out the door. The scars are real, even when they’re invisible.
Okay, So What Do You Actually Do?
Right. Let’s get practical. There are broadly two scenarios: you want to try to repair things, or you need to get out. Both are valid. Neither is easy. Here’s what actually helps.
1. Name what’s happening
You cannot address what you refuse to acknowledge. Clinical psychologists recommend journaling your experiences and comparing your written notes with objective facts — a technique that helps counter gaslighting and self-doubt. Therapists use the method “name it to tame it,” which involves labelling your emotions to shift your brain from raw reaction to thoughtful response. This literally reduces amygdala activity. Science is wild.
2. Set boundaries — and mean them
A boundary without a consequence is just a suggestion. Research published in the International Journal of Research Publication and Reviews (2025) is clear that establishing and enforcing boundaries is fundamental to both managing and recovering from toxic dynamics. Identify your values, communicate the boundary directly, and hold the line — even when it’s uncomfortable. Especially when it’s uncomfortable.
3. Rebuild your support network
Toxic relationships often succeed by isolating you. Reversing that isolation is one of the most powerful things you can do. Tell at least one person what’s going on. Reach out to a friend you’ve let drift. Being witnessed and believed matters enormously — and it breaks the silence that toxic dynamics depend on.
4. Get professional support
Therapy isn’t a last resort. It’s a first-rate tool. Evidence-based approaches recommended by American and Australian practitioners include Cognitive Behavioural Therapy (CBT) for reframing thought patterns, EMDR for processing trauma, and Dialectical Behaviour Therapy (DBT) for regulating emotional responses. Trauma-informed care is particularly effective for those who have experienced prolonged emotional abuse.
A 2025 systematic review published in a peer-reviewed journal confirmed that professional interventions — including solution-focused brief counselling — significantly help individuals develop practical coping strategies, rebuild self-esteem, and regain control of their emotional lives. You don’t have to figure this out alone, and you shouldn’t have to.
5. Prioritise your physical health
It sounds basic, but chronic stress from toxic relationships genuinely depletes the body. Aim for 7–9 hours of sleep to support mood regulation. Move daily — even a 20-minute walk lowers cortisol. Limit alcohol, which numbs pain short-term but worsens depression long-term. Your body is recovering from something real.
If You’re Leaving: What Helps
Leaving a toxic relationship — especially a long-term or deeply entangled one — is not a single event. It’s a process. And it’s rarely linear. Research consistently shows that people leave and return multiple times before leaving permanently, and that’s not weakness. That’s the reality of trauma bonding and attachment.
Practical steps that help include:
- Document incidents — dates, what was said, how you felt — especially if there are legal or safety concerns
- Lean on your support network before you leave, not just after
- Create a safety plan if there’s any risk of retaliation — 1800RESPECT (Australia) and the National Domestic Violence Hotline (USA) both offer guidance
- Give yourself permission to grieve what could have been, not just what was
- Begin rebuilding your identity outside the relationship — old hobbies, dormant friendships, new interests
The Australian Institute of Health and Welfare’s 2025 family and domestic violence data shows we’re slowly making progress — awareness is growing, more people are seeking help, and services are improving. But the numbers remain sobering: in 2024–25, 58 women and 15 men lost their lives at the hands of a current or former partner in Australia. That’s more than one woman every week. If you or someone you know is in danger, please reach out to 1800RESPECT (1800 737 732) in Australia or the National Domestic Violence Hotline in the US.
Toxic Relationships – The Bottom Line
Toxic relationships are not a personal failing. They are not proof that you’re too sensitive, too demanding, or too much. They are patterns — often rooted in the other person’s unresolved issues — that happen to have enrolled you as a co-star without your full consent.
Recognising them is the hardest part. Acting on that recognition is the bravest part. And rebuilding after them — whether you stay and fight for change, or leave and fight for yourself — is the most important part.
You deserve a relationship that doesn’t require you to shrink. And no amount of love — or fear of loneliness — is worth your long-term mental and physical health. Full stop.
