A partner with narcissistic personality disorder. How do you recognise harmful patterns and look after yourself?

The word “narcissist” comes up in conversations about relationships more often than ever. It is often typed into a search engine by someone who has felt for months that something in their relationship is wrong, but cannot quite name it: it started like a fairy tale, and now every conversation ends in guilt and their own memory feels less and less reliable.

Whether a relationship is harmful is shown above all by patterns that keep repeating: a very intense beginning, swings between admiration and coldness, an outburst or days of silence after every remark, double standards, being cut off from the people close to you and growing doubt in your own memory. You do not need the other person to have a diagnosis to notice these patterns and look after yourself.

In this article we explain how narcissism differs from narcissistic personality disorder, when the label “narcissist” does more harm than good, and what you can do if you recognise your relationship in this description. We write about a partner of any gender, because narcissism has no gender. Research finds it slightly more often in men, but it also occurs in women and in same-sex relationships. We give this less often described side its own section.

Narcissism, narcissistic traits and NPD are not the same thing

Narcissism is a personality trait that all of us have to some degree: the need for recognition, the wish to be noticed, enjoying admiration. Psychology describes it as a continuum: from mild, ordinary expressions, through marked narcissistic traits that make relationships difficult, to narcissistic personality disorder (NPD).

Narcissism is not the same as high self-esteem. A person with healthy self-esteem thinks: “I am fine as I am”. A person with strong narcissistic traits needs to believe “I am above others” and needs constant confirmation of this from outside. That is why a partner’s self-confidence on its own is not a warning sign.

Narcissistic personality disorder is a clinical diagnosis. According to the DSM-5-TR, it is a lasting pattern of grandiosity, need for admiration and lack of empathy that begins by early adulthood at the latest and shows up across many situations. A diagnosis requires at least five of nine criteria, including a belief in one’s own uniqueness, expecting special treatment, exploiting others, envy and arrogance. The pattern must also clearly interfere with life or cause distress.

Estimates of how common NPD is vary widely: from less than 1% to around 6% of adults, depending on the method. In the WHO classifications, narcissistic personality disorder has never been a separate main diagnosis, and the latest ICD-11 describes personality disorders by severity and prominent traits. This shows that even among specialists the line between “a difficult character” and a disorder is not obvious.

A diagnosis is made by a psychiatrist or psychologist after assessing the person concerned. It cannot be made from a partner’s description or an online test. And the good news is that you do not need this diagnosis to look after yourself. If, on the other hand, you are wondering about your own personality, at Oddech you can have a SCID-5 assessment, a structured diagnostic interview.

Grandiose and vulnerable (covert) narcissism

The popular image of a narcissist is someone loud, self-assured and self-absorbed. This is known as grandiose narcissism. Researchers also describe a second form: vulnerable narcissism, often called covert. Such a person may seem shy, withdrawn or “unappreciated by the world”. Underneath there is a similar need for admiration and a similar difficulty in seeing the other person, and criticism triggers intense shame, resentment and withdrawal rather than an outburst.

In many people the two forms alternate: confidence and charm in public, hypersensitivity to every remark at home. That is why lists of “narcissist traits” often do not match reality, and the person in the relationship hears from friends: “but he is so nice” or “but she is so warm”.

Narcissism in women: when the harmful partner is a woman

Articles about narcissism almost always describe a man. Research does show that men score slightly higher on average on narcissism scales and make up the majority of people diagnosed with NPD. The difference, however, mainly concerns grandiose narcissism, especially entitlement and a tendency to exploit others. In vulnerable narcissism there is practically no difference between the sexes.

This is why narcissism in women can be harder to notice: it more often does not fit the image of a loud, self-assured “narcissist”. The patterns described in this article look the same regardless of gender: constant criticism and comparison with others, punishing with coldness, inducing guilt, a fierce reaction to any remark, control presented as jealousy.

Men in such relationships often find it harder to ask for help. They hear that “a man should cope”, they feel ashamed to talk about humiliation or control, and the people around them are more likely to dismiss their complaints as exaggeration. Yet psychological abuse is abuse regardless of the gender of the person experiencing it. The numbers at the beginning of this article, including Niebieska Linia, are also for men and for people in same-sex relationships.

Narcissism or psychological abuse?

The question “does my partner have NPD?” is about the other person’s personality. For your safety, a different question matters more: is what is happening abuse? Humiliation, intimidation, controlling your phone and money, cutting you off from people close to you or systematically punishing you with silence are psychological or economic abuse, whether or not the person doing it has any diagnosis.

Since 2023, Polish law on preventing domestic violence also covers people who are or have been in a stable relationship, even if they never lived together, as well as former spouses. The law also explicitly names economic abuse and abuse using phones or the internet. This means you can contact Niebieska Linia even if you do not share a home and are not married.

How to tell that a relationship is hurting you

Instead of asking “is this a narcissist?”, it is worth asking: “what is happening to me in this relationship?”. The patterns below appear in relationships with people who have strong narcissistic traits, but also in other harmful relationships. What matters is whether they keep repeating, not a single argument.

A very intense beginning (love bombing)

At the start there is a lot of everything: messages from morning till night, declarations that “no one has ever understood you like this”, quick plans for a shared future. Intensity in itself is not a bad thing. The warning sign is a pace you have no say in, and admiration that disappears as suddenly as it appeared the first time you do something your own way.

Admiration alternating with coldness

After a period of idealisation come criticism, belittling and distance. Then tenderness and promises again. This cycle makes you try even harder to get back to “the good times”. The good moments are real, but they come unpredictably, and it is exactly this unpredictability that binds most strongly.

Your feelings stop counting

When you say something hurt you, the conversation quickly turns back to the other person: how they feel, what they have sacrificed, how tired they are. You are left feeling that your needs are “too much”, while theirs are obvious.

Criticism leads to an outburst or the silent treatment

Even a gentle remark ends in an attack, sarcasm or days of silence. Over time you learn to say nothing so as “not to spoil the mood”. The silent treatment becomes a form of punishment when its purpose is to make you apologise, regardless of what actually happened.

Double standards

The other person can be late, flirt or forget what you agreed. When you do the same, you hear that you lack respect. The rules in the relationship change depending on whom they serve.

Fewer and fewer of your people

Your friends “are a bad influence”, your family “interferes”, and time spent without your partner ends in reproaches. Isolation is rarely open. More often it comes as jealousy, which is easy to mistake for care.

Gaslighting: when you start doubting your own memory

Gaslighting means undermining someone’s perception of reality: “I never said that”, “you are blowing everything out of proportion again”, “you are oversensitive, it is your hormones”, “a man shouldn’t get so worked up”. An occasional difference in memories happens in every relationship. We speak of gaslighting when the undermining is constant and leads you to stop trusting your own perceptions and to trust only the other person’s version.

The researcher Paige Sweet points out that gaslighting works most powerfully where it is supported by stereotypes, for example about “hysterical” women, about men who “cannot be victims”, or about people with mental health difficulties who “imagine everything”. That is why it is so easy to take it as your own fault.

What helps if you suspect gaslighting:

• Write down important conversations and events straight away, with the date, somewhere your partner has no access to. Not to present evidence, but to have a reference point for yourself.
• Check your perceptions with a trusted person outside the relationship.
• Do not try to win the argument about “what really happened”. It is enough to say: “we remember it differently, this is how I remember it” and end the discussion.

When it is probably not narcissism

The popularity of the word “narcissist” has another side. The label gets attached to anyone who has disappointed us, and then, instead of helping, it shuts the conversation down. It is worth distinguishing a few situations.

Someone sets boundaries. A person who says “no”, needs time for themselves or disagrees with you is not a narcissist because of that. A healthy relationship includes conflict.

Someone behaved selfishly about one thing. A lack of attention during a difficult period, difficulty apologising or insensitive behaviour after a break-up can hurt, but they do not show a lasting personality pattern.

Someone is struggling with something else. Depression, burnout, ADHD or difficult childhood experiences can look like a lack of interest in the other person. The difference often lies in whether that person sees the problem, takes responsibility for it and tries to change something.

You argue, but you both do. If the same conflict keeps coming back in your relationship, but neither of you is afraid of the other and you are both able to apologise, it is more likely a vicious circle of arguments than narcissism. We write more about it in the article Constant arguing in a relationship: why you keep having the same fight.

The opposite is also true: harmful behaviour is harmful whether or not a personality disorder lies behind it. You do not have to prove that someone “is a narcissist” to have the right to say “this hurts me” or to leave.

Why it is so hard to leave

People leaving such relationships often ask themselves why they stayed so long. The answer is rarely: because they were naive.

A lot keeps a person in such a relationship. There is the hope that the person from the beginning will come back. There is shame in front of others, who see a charming partner by your side. There is a shared home, finances, sometimes children. And when you hear for a long time that you are the one overreacting, you start to believe it, and it becomes hard to make decisions based on your own perceptions.

Researchers also describe traumatic bonding: an attachment that grows stronger precisely because periods of harm alternate with periods of tenderness. A strong attachment to someone who hurts you is therefore not proof of weakness, nor that “it must be love after all”. It is a predictable response to a relationship in which closeness and pain come from the same person.

What you can do

Focus on behaviour, not on a diagnosis

Instead of “you are a narcissist”, something concrete works better: “when you don’t speak to me for three days after an argument, I feel you are punishing me”. A label provokes defensiveness; describing behaviour gives a chance for a conversation, if that chance exists at all. And if even a calm description is met only with denial and attack, that is important information too.

Set boundaries that depend on you

A boundary is not a request for someone to change, but information about what you will do. “If you start shouting at me, I will end the conversation and we will come back to it tomorrow” is a boundary. “Stop shouting at me” is a request you have no control over.

If the very thought of setting a boundary makes you afraid of how the other person will react, take that seriously. In that case, look after your safety and outside support first, and only then think about the conversation.

Reconnect with people outside the relationship

One trusted person who knows the situation is often the most important safeguard. They help you check whether your reactions are proportionate and give you a place where you do not have to prove anything.

If you are thinking of leaving, plan it

Leaving a person who is abusive or does not cope with losing control is often the riskiest moment of the relationship. It is worth sorting out documents, money, a place you can go to and a person who knows your plans in advance. After a break-up, many people choose to keep contact to a minimum or, if there are children, to limit contact to matters concerning the children, preferably in writing. If you are experiencing abuse, you can prepare a safety plan with a Niebieska Linia consultant.

Look after yourself after leaving

After such a relationship, people are often left with self-doubt, difficulty trusting others and recurring thoughts of “maybe it was my fault after all”. This is normal and usually fades with time, especially when you have support. If it does not fade, it is worth talking to a specialist.

When it is worth talking to a specialist

It is worth it when:

• you have been wondering for a long time whether something is wrong with you,
• you walk on eggshells in your relationship to avoid an outburst or silence,
• you have lost touch with people close to you and find it hard to reconnect,
• you are thinking of leaving but do not know how to do it safely,
• after a break-up you still cannot stop thinking about it or find it hard to trust someone new.

At a psychological consultation you can talk calmly about what is happening and, together with a specialist, think about what you need right now. If the difficulties last longer, individual psychotherapy can help you rebuild trust in your own perceptions and look at what makes setting boundaries hard. In an acute crisis, for example just after a break-up or when you are in danger, you can use crisis intervention.

You do not have to live in Poznań: an online consultation takes place by video call, also if you live outside Poland.

Frequently asked questions about a relationship with a narcissist

Can a narcissist change?

They can, but on one condition: that the person sees the problem themselves and wants to work on it. Research shows that in most people narcissistic traits weaken with age, and psychotherapy can help a person who engages in it of their own free will. There is still little research on treating NPD itself, however. Change cannot be made on someone else’s behalf: not with love, not with patience and not with better explanations.

Can a narcissist love?

People with strong narcissistic traits can feel attachment, longing and fear of rejection; they describe this themselves in research. The difficulty is that closeness often serves to maintain their sense of self-worth, so their feelings can be conditional: they last as long as the other person admires them and makes no demands. For you, however, a different question matters more: do you feel safe and respected in this relationship?

Do narcissists come back after a break-up?

Sometimes they do. After a break-up, many people experience attempts to win them back: apologies, promises of change, sudden tenderness or, on the contrary, accusations and pressure. It is worth deciding in advance how you will respond, and checking whether the words are followed by lasting changes in behaviour, not just a few good weeks.

Will couples therapy help in a relationship with a narcissist?

When there is a lot of conflict in a relationship, but both people want to change something and take responsibility for their part, couples psychotherapy can help a great deal. If, however, there is abuse, intimidation or constant undermining of your reality in the relationship, couples therapy is not the first step. Joint sessions can then become another place where one person controls the other. It is better to start with individual support.
