Am I Dating a Narcissist? A Self-Check Focused on Behaviour, Not Labels

Only a qualified professional can diagnose narcissistic personality disorder, and they would need to assess the person directly. But you don't need a diagnosis to decide whether a relationship is good for you. What matters is behaviour: a consistent lack of empathy, a sense of entitlement, a need for admiration, exploiting or controlling you, and cycles of charm followed by coldness or contempt. This self-check helps you look at those patterns.

You don't need a diagnosis to know whether a relationship is harming you. Behaviour tells you what you need to know.

Why focus on behaviour, not labels

"Narcissist" is widely used online to describe anyone selfish or hurtful. That can make it harder to think clearly: you may spend energy arguing about a label instead of looking at what's happening. Focusing on behaviour also helps whether or not your partner has a personality disorder; harmful behaviour matters either way.

The self-check

Answer "often," "sometimes," or "rarely" for the last three months.

Empathy 1. My partner shows little interest when I'm upset or struggling. 2. My feelings are dismissed or treated as an inconvenience.

Entitlement and admiration 3. My partner expects special treatment and gets angry when they don't receive it. 4. Conversations usually return to them, their achievements, or their problems. 5. They need constant praise, and criticism leads to anger or sulking.

Control and exploitation 6. Decisions are made to suit them, regardless of my needs. 7. They use guilt, anger, or silence to get their way. 8. I feel used — for money, status, practical help, or image.

The cycle 9. Periods of intense charm alternate with coldness or contempt. 10. After conflict, I end up apologising even when I wasn't wrong. 11. They rewrite past events so they're never at fault.

Effect on you 12. I feel worse about myself than before the relationship. 13. I find myself constantly trying to keep them happy.

What your answers suggest

Mostly "rarely": your partner may have some self-centred moments, like everyone, but the pattern isn't strongly present.

Some "sometimes": there may be problematic behaviours worth discussing directly, especially around empathy and fairness.

Several "often": the relationship shows a pattern that's likely harming you, whatever label applies. It's worth talking to someone you trust or a counsellor, and thinking about what you need.

If you feel afraid, controlled, or threatened, please contact a domestic abuse service. In the US, call 1-800-799-7233 or text START to 88788. In the UK, call 0808 2000 247.

What to do next

• Write down specific examples behind your "often" answers.
• Notice how your partner responds when you raise a concern calmly.
• Rebuild connections with friends and family.
• Consider individual therapy to help you think clearly.

A worked example

After reading articles online, Mia was convinced her boyfriend was a narcissist. She spent months arguing with him about it. When she worked through the behaviours instead, she noticed a clear pattern: he was charming in public, dismissive in private, and she always ended up apologising. Focusing on that pattern, rather than the label, helped her decide what she needed and what she wasn't willing to accept. That was far more useful than winning the argument about a diagnosis.

Common questions

Can I tell if my partner is a narcissist?

Only a professional can diagnose a personality disorder. You can, however, recognise harmful patterns of behaviour and decide what you need.

What are signs of a narcissistic partner?

Lack of empathy, entitlement, need for admiration, controlling behaviour, and cycles of charm and contempt are commonly described patterns.

Can a narcissist change?

Some people with narcissistic traits can change with sustained therapy, but it requires their motivation. You can't make them change.

Should I confront my partner about being a narcissist?

Labelling often leads to arguments. Focusing on specific behaviours and how they affect you is usually more productive.

Why do I keep going back to someone who treats me this way?

Cycles of charm and coldness can create a strong bond, because the good moments feel like relief. Recognising the cycle, and getting support from people outside the relationship, makes it easier to see clearly.

What if I recognise these patterns in myself?

Noticing them is a good sign. Many people have some self-centred habits. A therapist can help you build empathy and change patterns that hurt the people close to you.
