Dating a Narcissist: 9 Warning Signs of Narcissistic Behaviour
June 22, 2026
Narcissistic behaviour in relationships often starts with intense charm and slowly turns into a pattern of control, blame and emotional whiplash. Important note up front: narcissistic personality disorder is a clinical diagnosis only a professional can make. This article is about recognising behavioural patterns — not labelling a person — so you can protect yourself.
9 warning signs
- •Love bombing at the start — overwhelming charm and fast-tracked intimacy.
- •Everything eventually becomes about them; your needs get sidelined.
- •A striking lack of genuine empathy when you're hurting.
- •Gaslighting — you're made to doubt your own memory and perception.
- •Criticism disguised as jokes, slowly eroding your confidence.
- •Blame never lands on them; somehow it's always your fault.
- •Hot-and-cold cycles that keep you anxious and off balance.
- •Boundaries are ignored, tested or punished.
- •You feel smaller, more confused and less like yourself over time.
The narcissistic cycle
Narcissistic relationships often follow a recognisable loop: idealise, devalue, discard. First you're adored (love bombing), then slowly undermined (devaluation), then dropped or pushed away (discard) — sometimes followed by a return to start the cycle again. Spotting the cycle is what breaks its spell.
Gaslighting and self-doubt
Gaslighting is the most disorienting tool in the pattern: persistent denial of things that happened until you stop trusting your own perception. If you constantly find yourself apologising, second-guessing clear memories, or keeping a private record just to stay sane, take it seriously.
How to protect yourself
Reconnect with people outside the relationship — isolation is where this pattern thrives. Keep a clear record of events for your own grounding. Set boundaries and watch the reaction rather than the apology. And seek support: a therapist or trusted friend can help you see what manipulation is designed to obscure.
If the pattern is consistent and the relationship leaves you smaller, believe that evidence. Walking away from chronic disrespect isn't giving up — it's self-respect.
Frequently asked questions
How do I know if he's a narcissist or just selfish?
Selfishness is occasional; the narcissistic pattern is persistent and cyclical — love bombing, devaluation, gaslighting, lack of empathy. Only a professional can diagnose narcissistic personality disorder, but you can absolutely recognise and respond to the behaviour.
What is gaslighting in a relationship?
Gaslighting is manipulation that makes you doubt your own memory and perception — denying things that happened until you stop trusting yourself. Persistent self-doubt around one person is a major warning sign.
Can SIGNALS detect narcissistic patterns?
SIGNALS analyses behaviour in a conversation and flags manipulation, love bombing and inconsistency. It's a behavioural insight tool, not a clinical diagnosis — but it can help you see patterns clearly enough to act.
