Why Does She Act Like This? The High Conflict Ex Explained
Why does the high conflict ex act so crazy? See what’s really behind her chaotic behaviour – and why the drama is not as random as it seems.
Have you ever found yourself wondering why your partner's high conflict ex seems to make everything so difficult? Why simple conversations turn into arguments? Why plans are constantly derailed by last-minute changes?
"Why can't she just be normal??"
It's exhausting, isn't it? Just when you think things might calm down, more drama arrives out of nowhere. Her behaviour often seems irrational and deliberately designed to make your life difficult.
But here's something that might change your perspective: Her actions aren't about you at all. They're part of a predictable pattern that serves a purpose for her, even while creating chaos for everyone else. Understanding this pattern can be your first step toward freedom from the drama cycle.
What Is a High Conflict Ex?
So what exactly is a "high conflict person"? It's not just a label for someone difficult. It refers to a specific pattern of behaviour that increases conflict rather than resolving it. The issues come and go, but their personality traits create the same conflicts over and over again.
High conflict people typically display four main behaviours, and once you recognise these, you'll start to see just how predictable she really is:
A preoccupation with blaming others
Black and white thinking – meaning there's no middle ground or room for compromise
Unmanaged emotions – way out of proportion to what’s happening
Extreme behaviour or threats – things that most people would never do
See Why Does My Husband's Ex Cause So Much Drama? for more on these behaviours, to help you recognise them.
How To Know If She’s High Conflict Or Just Difficult
For many stepmums, the question of whether she's high conflict or not isn't always clear, because sometimes she seems to be, and other times she seems not to be. Here’s how to tell. Most people have a baseline behaviour that is reasonable. When stressed or upset, they may act out of character, but they usually return to that baseline once things settle.
But a high conflict person is different. Their baseline returns to the same high conflict behaviour patterns: a preoccupation with blaming others, black and white thinking, unmanaged emotions, and extreme behaviors. So look for these patterns showing up across different situations over time. If she’s high conflict, you’ll see those four behaviours show up consistently.

It Feels Personal, But Her Toxic Behaviour Is Not About You
It’s completely normal to feel thrown off by her behavior. She accuses you of things you didn’t do and blames you for everything. So of course it feels personal. And it’s natural to think that we must have caused it somehow. "Maybe if I was kinder…”
But the thing to understand is – what she thinks, how she acts, has nothing to do with you. High conflict people don't see reality the way most people do. They view the world through distortions in their thinking that lead them to believe they are the victim and others are to blame. And they believe their distorted thoughts and act on them as if they are true.
They then “defend” themselves by taking aggressive action towards the person they believe is to blame. When you understand this, you can see her behavior as a pattern rather than a personal attack. See Why Does The Ex Hate Me No Matter What I Do for help on not taking it personally.
She Is Predictable – Once You Understand Her Patterns, Her Behaviour Makes A Lot More Sense
The most powerful insight I can share with you is that high conflict behavior isn't random. It follows distinct, predictable patterns that show up again, and again, and again. And once you know what these are, her behaviour starts to make a lot more sense. You can learn to see the drama coming, and prepare instead of being blindsided all the time.
The reason her behaviour feels so chaotic is because those patterns don’t follow normal logic – they follow emotional logic. High conflict people don’t see the world as it is, they see it as they feel. If they feel attacked or abandoned, for example, then that must be what’s happening. And because the emotions show up predictably, the behaviour does too.
I show you some of the most common patterns and how to see them in your situation in How Do I Stop Getting Blindsided by My Husband's Toxic Ex? This is how you can start to predict her behaviour instead of being constantly caught off guard.
How to Tell If She’s A Narcissist (Or Something Else)
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. These are:
Narcissistic – the "I'm superior, you're nothing" type.
Borderline – The "love you, hate you" Type
Antisocial – The “cruel con artist" type
Paranoid – The highly suspicious type
Histrionic – The dramatic, accusatory type
Not everyone with these personality traits becomes high conflict, and not every high conflict person fits these patterns. But if you think she might fit one or more of these, you might finally have an explanation for behaviors that have been driving you crazy. See Is My Husband's Ex Wife a Narcissist? for a run down on all of them.
The more you understand what you're dealing with, the easier it becomes to stop second-guessing yourself or believing that the right words will somehow make things better, and start using strategies that actually work.
