Is My Husband's Ex Wife a Narcissist?

Narcissist is the word everyone uses – but there's 5 high conflict personalities. Here's how to tell what you're dealing with.

If you’re hearing things from your partner’s ex like "I'm their mother, you're just the woman who married their father" you could very well be dealing with a narcissist. Narcissistic personalities are driven by a desperate need to prove they're better than everyone else. 

But the High Conflict Institute believes that people who become high conflict often have one or more of five personality disorders (or traits of those disorders): narcissistic, borderline, antisocial, paranoid, and histrionic. Once you discover what type you’re dealing with, you might finally have an explanation for behaviours that have been driving you crazy. 

As you read further, which feel familiar? Is there one, or maybe more than one pattern? If you do recognise any, it might be the key to finally understanding what you're dealing with. Then you can learn to respond more strategically.

The Narcissistic "I'm superior, you're nothing" type

Narcissistic personalities have a desperate need to be seen as better than everybody else.  She doesn't collaborate – she competes. She views the children as extensions of herself rather than independent individuals. When they do well, it's because of her. When they struggle, it's your negative influence.

She'll publicly humiliate you or your partner, but in ways that make her look like the concerned, superior parent. For example, she may tell teachers that all important decisions should go through her because "their father doesn't really understand the children like I do." She may complain about having to do everything herself, while also refusing to coordinate on anything.

Sitting underneath this behaviour is a deep fear of being seen as inferior or inadequate. Although they may appear highly confident, their self-esteem is fragile. They rely heavily on validation from others, and when that validation is challenged, they see it as a personal attack. They react defensively, driven by a need to protect their self-image and maintain a sense of control or superiority.

The Borderline"love you, hate you" type

Borderline personalities have an intense fear of abandonment. They see signs of rejection everywhere, even when none exist. Things that seem minor to others, like a change of plans, can trigger a full emotional crisis. She doesn't just get angry – she experiences "borderline rage," which seems completely out of proportion to the situation. She might scream things that make no sense, then later act like nothing happened.

Borderline personalities have a tendency to rewrite history based on how they're feeling at the time. Because emotions so strongly shape their perception of events, they may genuinely remember conversations and situations differently from others involved, and then insist their version is the correct one.

In co-parenting situations, she may struggle when the children form bonds with you because she sees these relationships as threatening to her rather than beneficial to them. This might include speaking negatively about you to the children, creating conflicts around events where you might be present, or demanding that you have no role whatsoever. 

The Antisocial “cruel con artist" type

The antisocial, or sociopathic, pattern is not driven by emotional fears like the other – it's driven by a desire to dominate, control, and win at any cost. People with sociopathic traits are often charming at first, but over time, a pattern of manipulation, dishonesty, and disregard for rules often emerges. 

They lie frequently, and when confronted with evidence, they don’t show shame or remorse. They might attack you for "spying" or simply move on to the next lie without missing a beat. In co-parenting situations, they view arrangements in terms of winning and losing rather than what’s best for the children, and their involvement is driven more by convenience or image. 

For example, she may enthusiastically attend high-profile events like sports finals, while avoiding routine responsibilities like homework supervision or medical appointments. She might promise the children extravagant birthday celebrations, then deliver nothing while blaming your partner for "making it difficult." 

With this personality type, pay attention to any gut feeling that something just doesn't feel right – like they are cold and disconnected while saying all the right things. 

The Paranoid “highly suspicious” type

Paranoid personalities view the world with a deep sense of suspicion and distrust. They assume others have hidden motives and often interpret neutral or even positive actions as deceptive, manipulative, or threatening. They're constantly on alert, looking for signs that something isn't what it seems. What's challenging is that they can sound completely reasonable when explaining their concerns.  

In co-parenting, she doesn't just misinterpret you and your partner’s actions occasionally - EVERYTHING you do has sinister meaning. You enrolled the child in piano lessons? You're trying to make her look bad for not being able to afford them. You took them to the doctor for a routine check-up? You're building a case that she neglects their health. 

She may repeatedly involve authorities – calling child protection, police, filing court motions – because she genuinely believes you're dangerous. She remembers every perceived slight forever and sees them all as evidence of your "deliberate pattern of harm." She may say things like, "I know what you're really doing," or, "You can't fool me," even when discussing minor matters.

The Histrionic “dramatic, accusatory type

People with histrionic personalities have a strong need to be the centre of attention. They express emotions in dramatic ways, and their communication is often colourful and emotional, yet lacking in substance and detail. 

One defining characteristic is that their stories become more dramatic over time – each retelling adds more drama and victimisation that wasn't in the original story. They don't consciously realise they're performing though – to them, everything really does feel like "the most terrible thing ever" or "completely devastating" in the moment. But their intense emotions are often short lived, quickly moving from one emotional state to another.

In co-parenting situations, there always seems to be something urgent, upsetting, or unfair happening, and they can turn routine matters into major crises that demand everyone's attention. She'll send emotional group messages about parenting issues that should be handled privately. She'll be "devastated" about something but posting happy selfies an hour later. 

At the core of this pattern is often a fear of being overlooked, unimportant, or forgotten, and they've learned that drama and crisis gets them the attention they desperately crave.

FAQs

What if she fits more than one of these patterns, or none? 

That’s also normal. While there is a high correlation, not everyone with these personality traits becomes high conflict, and not every high conflict person fits these patterns. And some may exhibit traits from more than one of these patterns. 

How do I know if it's a genuine pattern or just how she acts under stress? 

Look for patterns over time, not individual incidents. Anyone might act paranoid during a custody battle – but paranoid personalities are suspicious even during calm periods. Anyone might lie to avoid consequences – but antisocial personalities lie even when the truth would serve them better.

Does she realise she might have a personality disorder? 

Probably not, and we don’t know she does unless she’s been diagnosed by a clinical psychologist or psychiatrist. These patterns are unconscious. The person displaying them usually has no idea they're doing it. They believe their reactions and behaviors are completely justified given what they perceive is happening around them.

Should I tell her which pattern I think she fits? 

No. This information is not so you can label anyone – in fact, if you do, they will make life a lot harder for you. Instead, use it to help you develop your own understanding of the patterns so you can protect yourself and your family.

These patterns are deeply ingrained, often from early childhood – and this behaviour isn't about you. If you recognised a pattern today, you now have more of an understanding of what you're dealing with. Use that understanding to protect yourself and your family.
