I have spent more than 10 years as a licensed marriage and family therapist, and I tell my clients the same thing I will tell you: the first way to deal with a toxic relationship is to notice how you feel right after you talk to your partner. If you walk away drained, anxious, or smaller than you felt an hour before, and it keeps happening, that pattern says more than any single argument can.
A toxic relationship is one where the everyday dynamic leaves you consistently worse off, depleted, criticized, controlled, or on edge, even when real love is still there. It is not one bad week or one hard season. It is a repeated pattern that slowly wears down your sense of who you are.
You can love your partner and still be in a relationship that is hurting you. Both things are true at once. Below, I will cover the signs I look for, whether a toxic relationship can actually change, how it differs from abuse, and how to leave safely if that is where you are.
What a toxic relationship actually feels like
Most people expect toxicity to look like constant shouting. In my experience, it is quieter than that. It shows up as the feeling you carry after the conversation ends.
When my team and I built Nebbi, a therapist-designed emotional wellness app, we asked people to name how they felt in the moment using nine emotional states. Across the first 14,200 check-ins, the states people reported most were Overwhelmed at 24 percent, Anxious at 19 percent, and Drained at 16 percent. Those are the same feelings a strained relationship tends to leave behind, the quiet version of the invisible mental load so many women already carry.
One state surprised us. Many users said they had never had a word for Disconnected, the numb, going-through-the-motions feeling of sitting next to someone and still feeling alone. In a toxic relationship that numbness is common, and naming it is the first step to acting on it.
Try this for one week. Right after each interaction with your partner, name the feeling in a single word and write it down. One rough day is just life. But if drained, anxious, or disconnected keeps showing up, that repetition is your data, and it is hard to argue with.
What are the red flags of a toxic relationship?
The clearest red flag is a pattern that repeats and does not improve after you name it. A single flaw is not toxic. A recurring dynamic that leaves one or both of you worse off is.
The contrast between healthy and toxic patterns usually looks like this.
| In a healthy relationship | In a toxic relationship |
|---|---|
| You share wins and cheer each other on | Your wins turn into competition or get ignored |
| Conflict stays about the issue | Conflict slides into sarcasm, criticism, and contempt |
| Space and privacy are respected | Check-ins feel like monitoring and control |
| You repair after a fight | Resentment builds quietly and goes unspoken |
| You feel more like yourself | You feel smaller, tired, and unsure |
A few of these are worth a closer look. Contempt is the one I watch for most. Dr. John Gottman, who studied thousands of couples at the University of Washington, found that contempt, meaning sarcasm, mockery, eye-rolling, and talking down to a partner, is the single greatest predictor of divorce in his research. When respect turns into disdain, the relationship is in real trouble.
Control is another. Frequent demands to know where you are, who you are with, and how you spend money can feel like care at first. Over time it eats away at the trust that grows when partners respect each other’s need for personal space. The CDC counts this kind of psychological aggression, using words to harm a partner emotionally or to control them, as a form of intimate partner violence, and I will come back to that line below.
Persistent jealousy works the same way. A flash of envy is normal, but constant mistrust, as the Cleveland Clinic explains, slowly poisons a connection. So does chronic stress. If your body tenses every time your partner walks in, that is information worth taking seriously. Round out the list with dishonesty and steady disrespect, like chronic lateness, broken plans, or the quiet signs someone is not being honest with you.
Can a toxic relationship become healthy again?
Sometimes, yes, but only when both partners genuinely want to change. That is the honest answer. If just one person is doing the work, the odds are low.
In my clinical experience, the couples who turn things around share a few habits. Both people admit their part instead of keeping score. Both trade blame for curiosity. And both get help when they are stuck, because a good couples therapist gives you a neutral third person and a structured way to break old patterns. It comes down to what accountability looks like in practice: owning your behavior without a “but” attached.
Not every difficult partner is “toxic”
This is where I push back on a lot of what you will read online. We have started calling every hard moment toxic and every difficult person a narcissist. As a therapist, I think that habit does harm. Social media has trained us to reach for a clinical label the second a relationship gets uncomfortable. But conflict is not the same as toxicity, and a partner who annoys you is not automatically a narcissist. Real toxicity is a sustained pattern that hurts you over time, not a person who loads the dishwasher wrong or needs quiet after work. Mislabeling normal friction as a disorder can end relationships that were fixable, and it pulls your attention away from the specific behaviors that actually need to change. Name the behavior, not the diagnosis.
How do you fix a toxic relationship?
If both of you are committed, repair starts with a few concrete changes, not one grand gesture. These are the ones I assign most often.
- Work forward, not backward. Rehashing every old wound keeps you stuck. Name the pattern, then focus on what each of you will do differently this week.
- Lead with “I” statements. “I feel ignored when my calls go unanswered” lands better than “You never call.” One describes your experience. The other starts a fight.
- Trade blame for a question. Try “Help me understand what happened” in place of “You always do this.”
- Own your half out loud. Both partners name their part in the pattern. Real change starts here, and it looks a lot like owning your mistakes without excuses.
- Get support. A couples therapist, a trusted friend, or a support group gives you perspective you cannot find from inside the relationship.
- Keep checking in with yourself. Watch whether the heavy feelings ease week to week. Progress tends to show up in your body before it shows up in words.
Toxic relationship vs. abuse: how to tell the difference
Toxicity and abuse can overlap, but they are not the same, and the difference changes what you should do next. Toxic behavior is often mutual and unintentional. Two people fall into patterns that hurt each other with no one seeking power. Abuse is different. It is a pattern of one person trying to gain and keep power and control over another.
That distinction carries weight. The National Domestic Violence Hotline describes abuse as a set of behaviors used to gain control, which is why advocates map it with a “Power and Control Wheel.” Abuse can be emotional, financial, or physical, and it often starts small, which makes it hard to see from the inside. This is more common than most people think, and it is never the survivor’s fault. The CDC reports that more than 1 in 3 women and more than 1 in 6 men experience physical violence, sexual violence, or stalking by an intimate partner in their lifetimes, and it links that violence to lasting effects on the heart, digestive, and nervous systems. If you recognize control, intimidation, isolation from the people you love, or fear inside your own home, that is beyond toxic, and it deserves specialized help, not a communication workbook.
How to leave a toxic relationship safely in 2026
If you have decided to leave, your safety comes first, especially when there is any pattern of control or abuse. Leaving can be the most dangerous moment in an abusive relationship, so plan before you act.
This is what I tell people who are getting ready to go.
- Talk to a professional first. A therapist or a domestic violence advocate can help you build a safety plan. The National Domestic Violence Hotline is free, confidential, and open 24/7 at 1-800-799-7233, or text START to 88788.
- Lean on your people. Tell trusted friends or family. They can offer a place to stay, help you move, or simply be there.
- Do not have the hard conversation alone if you feel unsafe. Bring someone you trust, or skip the in-person talk entirely if leaving quietly is safer.
- Protect your communication. Block their number and social profiles if contact makes it harder to stay gone.
- Give yourself time to heal. Leaving drains you even when it is the right call. Rest, lean on support, and do not rush into the next relationship.
If you are in immediate danger, call 911. If your mental health is suffering through this, the 988 Suicide and Crisis Lifeline is available any time by call or text. A daily check-in habit can help you spot the pattern early, but it is a wellness tool, not therapy or a crisis line, so lean on the resources above when you need real support.
Dealing with a toxic relationship starts with the pattern, not the fights. Notice how you feel, name it, and decide from there whether this is something you repair together or step away from. Building the habit of a two-minute check-in with yourself makes that pattern impossible to ignore, which is exactly why we designed Nebbi that way. The goal is simple: a relationship that leaves you feeling more like yourself, not less.
FAQs
What is a toxic relationship?
A toxic relationship is one where the everyday dynamic leaves you consistently worse off, depleted, criticized, controlled, or on edge, even when love is still present. It is a repeated pattern rather than one bad week, and over time it wears down your sense of who you are.
Can a toxic relationship become healthy again?
Sometimes, but only when both partners genuinely want to change. In clinical practice, the couples who recover tend to own their part, trade blame for curiosity, and get outside help. If only one person is doing the work, lasting change is unlikely.
How is a toxic relationship different from an abusive one?
Toxic behavior is often mutual and unintentional, while abuse is a pattern of one person seeking power and control over another. The CDC reports that more than 1 in 3 women and more than 1 in 6 men experience intimate partner violence in their lifetimes. If you notice control, intimidation, isolation, or fear, that is abuse and needs specialized support.
What are the first signs of a toxic relationship?
The earliest sign is usually a feeling, not a fight. If you regularly feel drained, anxious, or disconnected after time with your partner, that pattern matters. Across the first 14,200 check-ins in the Nebbi app, the most reported emotional states were Overwhelmed, Anxious, and Drained, the same feelings a struggling relationship tends to produce.
Can you love someone and still be in a toxic relationship?
Yes. Love and harm can exist at the same time. Caring deeply about your partner does not cancel out a pattern that leaves you smaller, tired, or unsure of yourself, which is why it helps to watch the pattern rather than any single good or bad day.
Should I try to fix a toxic relationship or leave?
If both partners are committed to change and there is no abuse, many toxic patterns can improve with honest communication and couples therapy. If there is a pattern of control, intimidation, or fear, prioritize a safe exit and reach out to a professional or the National Domestic Violence Hotline.
Where can I get help for a toxic or abusive relationship?
A licensed therapist or a domestic violence advocate can help. The National Domestic Violence Hotline is free and confidential at 1-800-799-7233, or text START to 88788. If you are in crisis, the 988 Suicide and Crisis Lifeline is available by call or text, and you should call 911 in an emergency.
