There are many ways to answer the question, “What does it mean to be in a toxic relationship?”
This article will provide the basic definition of a toxic relationship. You will also learn more about the different ways a relationship may be toxic. The goal is to help you identify if there are any toxic traits in your own relationships because you must name this problem before you can heal the issues.
What It Means to Say a Relationship is Toxic
The definition of toxic from Oxford languages includes “poisonous,” and “very harmful or unpleasant in a pervasive or insidious way.”
From this definition, you can see that the easiest way to describe a toxic relationship is that:
Toxic relationships are those that are harmful to the mental, emotional, or physical wellbeing of one or both partners.
Insidious means proceeding in a gradual, subtle way, but with harmful effects. An example of this “insidious” harm in toxic relationships is gaslighting. Bit by bit, someone who is gaslighting you, works to make you question your reality. This is done in subtle ways that make you wonder if you’re the “crazy” one.
What Types of Relationships are Toxic
There are numerous ways a relationship may be toxic. But frequently, these relationships involve codependent and narcissistic symptoms in partners.
People with codependent symptoms and those with narcissistic symptoms are often a perfect complement for one another’s emotional and behavioral hooks. For example, a codependent aims to please others to find self-worth while a narcissist craves attention. Ross Rosenberg calls this the “human magnet syndrome.”

The Push/Pull Dynamic
Frequently, such relationships have a push/pull dynamic. You also may have heard this described as a “runner/chaser” dynamic.
Being in an on-again/off-again relationship, a situationship, and being in a relationship that runs hot and cold are all examples of how this push/pull dynamic manifests in toxic relationships.
This type of pattern is also a feature of toxic relationships involving love addiction/love avoidance.
Love Addiction and Love Avoidance
Codependency expert, Pia Mellody, explains, “Love addicts focus almost completely on the other person they are addicted to; they obsessively think about, want to be with, touch, talk to, and listen to their partners, and want to be cared for and treasured by them.”
On the other side, the love avoidant will frequently create intensity outside of this relationship. This means they will often be unavailable for a variety of reasons including work, substance abuse, and at times affairs with other people to give some examples.

Attachment Theory and Toxic Relationships
The co-addicted cycle of love addicts and love avoidants also overlaps attachment theory. Love addicts present with more anxious attachment and Love avoidants have avoidant attachment.
Typically, people in their codependency have anxious attachment. And research indicates this insecure attachment is common in narcissists. Kaufman (2018) found that anxious and avoidant attachment can be associated with narcissistic traits.

The Spectrum of Toxic Relationships
Codependency and narcissism exist along a spectrum. On one end of the spectrum are people with codependency who completely sacrifice themselves to please others. On the other extreme end of the spectrum are grandiose narcissists who tend to be more abusive, manipulative, lack empathy and need consistent praise.
In the middle are people who have lost themselves in the relationship but still feel resentful and demanding at times. People with vulnerable narcissism also exist here. Vulnerable narcissism includes hypersensitivity to criticism, anxiety, depression, and feelings of inferiority alongside feelings of entitlement in their relationships.
Walking on Eggshells
You may also feel like you are walking on eggshells as a result of being a toxic relationship.
This is understandable especially considering abuse is present in many toxic relationships. In fact, researchers found that 43.9% of partners with those with pathological narcissism report abuse being present. Abuse may be emotional, psychological, verbal, financial, sexual, or physical in nature. Psychological abuse includes threats such as your partner saying they will leave if they don’t do what they want. Or they may say things like “If you really loved me you would [insert their desire here] to coerce you. This may also include sexual coercion and pressure.
Finally, they may also threaten to harm or kill you, a loved one, or themselves when they’re upset.
Toxic Relationships Can Be Unpredictable
In safe, healthy relationships there is a sense of security that you can trust your partner to be consistent and dependable. Here you know that when they tell you they will be home by 6pm they mean it as an example. You also know that even if there are problems, they’ll keep showing up to fix them.

However, in a toxic relationship, you really can’t predict what will happen next. You don’t know when, perhaps, your partner will do something rude, hurtful, or humiliating next for example. This may include calling you a name, making fun of your weight, lying about using drugs, or discovering they are cheating as examples.

You Can’t Communicate Together
Commonly, in toxic relationships, partners feel like they “can’t” communicate together. This often means that one or both partners at times will become aggressive. Perhaps they will yell or throw things. They may also prevent the other from taking a break from fights at times which further creates conflict and a lack of safety.

Other ways you may struggle to communicate include one or both of you shutting down or putting up walls with one another.

Toxic Relationships are Harmful to Your Wellbeing
Emotionally these relationships may feel “poisonous” in that one, or both, partners deteriorate mentally or physically. For example, if you find that you have less energy than you used to since you’ve begun dating your partner because they drain you, this is a sign of toxicity. Commonly, people get sick more often due to the exhaustion and stress of such relationships.
In toxic relationships, people frequently feel depressed and anxious as well.

You May Feel More Anxious in a Toxic Relationship
Toxic relationships are by nature, highly stressful. As such, people in toxic relationships frequently experience anxiety.
Symptoms of anxiety include:
- Struggling to fall asleep or stay asleep,
- Muscle tension including consistent jaw clenching or neck and shoulder pain,
- Being easily fatigued,
- Panic attacks,
- A sense of pressure in your chest,
- Your mind going blank, and
- Struggling to concentrate or focus
Why It Makes Sense You May Be More Anxious
A good clue you may be in a toxic relationship is if you feel more anxious, nervous, or unsettled. This anxiety may also manifest as a sense you can’t trust yourself. Or like you’re the “crazy” one in the relationship. This feeling is completely understandable and may be further reinforced by gaslighting.

Another common reason you may be more anxious is due to increasing money concerns. Researchers Day, Townsend and Grenyer (2022) found that of those partners of pathological narcissists they interviewed, 32% reported financial burdens created by the narcissist. This includes racking up debt, stealing, controlling money, and being completely dependent on their partner financially i.e., not having a job and expecting their partner to pay for everything.
You May Become Depressed
Depression is common in toxic relationships. Symptoms of depression include:
- Being tired no matter how much you sleep,
- Gaining or losing weight,
- Appetite issues (both feeling more and less hungry),
- Low self-esteem,
- Sleep issues, and
- A sense of being hopeless or powerless (like life isn’t worth living or like you are stuck)
