Narcissists are great at creating a facade of perfection, but there’s a whole lot of mess they don’t want you to see. They’re masters of manipulation and illusion, but there are some telltale behaviours that can give them away.
1. Their private meltdowns when things don’t go their way

When no one’s watching, they might throw a tantrum, break things, or unleash a torrent of verbal abuse. They have difficulty regulating their emotions and often react in extreme ways when they don’t get what they want. This side of them is rarely seen in public, as they carefully maintain their image of composure and control.
2. Their secret envy and resentment towards other people’s success

Narcissists might publicly congratulate you on your achievements, but behind closed doors, they’re seething with envy and resentment. They see your success as a threat to their own superiority and feel diminished by your accomplishments. This jealousy can fuel their manipulative behaviour and sabotage attempts.
3. Their relentless pursuit of validation and attention, even in private

They might constantly check social media for likes and comments, obsess over their appearance, or do whatever they can to get attention even when they’re alone. This insatiable need for external validation is often a way to compensate for their fragile self-esteem and deep-seated insecurities.
4. Their carefully curated online persona that masks their true self

Social media is a narcissist’s playground, where they can carefully curate their image and project an idealised version of themselves. They might post endless selfies, brag about their accomplishments, or create a false sense of happiness and success. But behind the filtered photos and curated captions, there’s often a deeply insecure and unhappy person struggling with a fragile ego.
5. Their habit of talking negatively about people behind their backs

Narcissists often gossip and spread rumours about others as a way to elevate themselves and tear others down. They might criticise your appearance, your choices, or your accomplishments, all while maintaining a friendly facade to your face. This two-faced behaviour is a hallmark of narcissistic manipulation and can be incredibly hurtful and damaging to relationships.
6. Their deep-seated insecurities and vulnerabilities that they refuse to acknowledge

Despite their outward confidence and bravado, narcissists are often deeply insecure and vulnerable. They might fear rejection, abandonment, or criticism. However, they refuse to acknowledge these insecurities, choosing instead to mask them with arrogance, grandiosity, and a constant need for validation.
7. Their tendency to isolate and control their partners or loved ones

Narcissists often try to isolate their partners or loved ones from their support network. They might criticise their friends and family, make it difficult for them to see others, or even try to control their finances and decisions. This isolation tactic is a way for them to exert power and control over their loved ones and to prevent them from seeing the narcissist’s true colours.
8. Their inability to apologise or admit fault, even when they’re clearly in the wrong

Narcissists have a fragile ego that can’t handle the thought of being wrong or imperfect. They will go to great lengths to avoid admitting fault, even if it means lying, gaslighting, or blaming others. This lack of accountability makes it difficult to resolve conflicts or build trust in a relationship with them.
9. Their collection of masks for different situations and people

Narcissists are chameleons, adapting their personality to suit their audience. They might be charming and charismatic around their boss, but rude and dismissive to service staff. They might present a flawless image on social media, while their private life is a chaotic mess. This constant shifting of personalities can be disorienting and leave you wondering who the real person is behind the masks.
10. Their fragile ego that crumbles under scrutiny

Despite their outward confidence, narcissists have a fragile ego that can easily be bruised. Any hint of criticism or disapproval can trigger a defensive reaction, ranging from anger and hostility to sulking and withdrawal. They can’t handle being challenged or questioned, as it threatens their carefully constructed image of perfection.
11. Their inability to handle rejection or failure

Narcissists have an inflated sense of self-worth and believe they deserve success in all aspects of their lives. When faced with rejection or failure, they often have a meltdown, blaming others for their shortcomings or resorting to self-destructive behaviours. They may also become even more manipulative and controlling in an attempt to regain a sense of power.
12. Their deep-seated fear of abandonment and vulnerability

Beneath their confident exterior, narcissists often harbour a deep-seated fear of abandonment and vulnerability. They might sabotage relationships, push people away, or create drama to avoid getting too close to anyone. This fear stems from a lack of trust and a belief that they are ultimately unlovable.
13. Their tendency to use love and intimacy as a form of manipulation

Narcissists often use love and intimacy as a weapon to control and manipulate others. They might shower you with affection and attention to gain your trust, only to later withdraw and withhold love as a form of punishment. This can be emotionally devastating and leave you feeling confused, hurt, and questioning your own worth.
14. Their exploitation of others’ weaknesses and vulnerabilities for personal gain

Narcissists are skilled at identifying and exploiting the weaknesses of others. They might use your insecurities against you, play on your sympathies, or manipulate your emotions to get what they want. They have little regard for the well-being of others and will happily use anyone they can to achieve their own goals.
15. Their inability to genuinely apologise or empathise with people

Even when confronted with their hurtful actions, narcissists struggle to offer a sincere apology. They might offer a half-hearted “I’m sorry,” but it’s usually followed by excuses, justifications, or even blaming the victim. They lack genuine empathy and remorse, making it difficult to resolve conflicts or rebuild trust.
16. Their constant need for external validation to prop up their fragile ego

Narcissists rely on external validation to maintain their sense of self-worth. They need constant compliments, admiration, and recognition to feel good about themselves. This insatiable need for validation can make them resort to attention-seeking behaviour, manipulate others, and engage in unhealthy competition.
