How to Stop Romanticizing Your Ex

Your Brain Isn't Keeping You Hung Up on Your Ex. It's Trying to Protect You from Feeling.

If you're weeks (or lets be honest, months) out of a relationship that you know wasn't right for you, and you still find yourself replaying the best moments on a loop at 11pm... you're not weak. You're not pathetic. And you're not still in love.

You're experiencing one of the most well-documented psychological phenomena in memory research. And once you understand what your brain is actually doing, it becomes a lot easier to stop letting it run the show.

The Science of Why They Still Seem Perfect

Here's something that might sting a little but also (I hope) feels like a relief: the version of your ex you can't stop thinking about isn't completely real. Not because you made it up. But because your brain has been quietly editing the footage.

This is called positive memory bias, also known as "rosy retrospection," the tendency for the brain to preferentially store and retrieve positive emotional memories over negative ones, especially following loss. Research shows that people who experience greater breakup distress tend to report higher frequencies of positive relationship memories, creating a painful reinforcing cycle: the more it hurts, the more your mind surfaces the good stuff, which makes it hurt more (del Palacio-González et al., 2017).¹

From a neuroscience standpoint, there's a clear mechanism behind this. The amygdala assigns emotional weight to memories, and the prefrontal cortex can actively suppress details that don't fit with our current emotional needs. In the aftermath of a loss, the brain has a vested interest in protecting you, and one way it does that is by softening the sharp edges of what actually happened. The painful moments get dimmed. The tender ones get amplified. And suddenly you're comparing your current reality to a highlight reel that has been through some fairly heavy post-production.

You're not missing them. You're missing the version of them your brain decided to keep.

There's also a loss aversion piece at play here. Behavioral research pioneered by Nobel laureate Daniel Kahneman shows that humans feel the pain of losses far more intensely than the pleasure of equivalent gains, which means a breakup doesn't just hurt, it registers to the nervous system as a threat.² When we're in threat mode, the brain reaches for anything that felt like safety--- and for many of us, that was the relationship. Even if the relationship itself wasn't actually safe.

Add to this what Is called the anxious-avoidant spiral which means: if you have an anxious attachment style, the emotional withdrawal of an ex can activate your nervous system in the same way any abandonment cue does, making the craving for reconnection feel physiological, not just emotional (Mikulincer & Shaver, 2016).³ It's not nostalgia. It's your attachment system misfiring in the absence of a secure base.

So How Can You Anchor Yourself In Reality?

The first steps Is understanding the positive memory bias and how your brain and nervous system are wired. Second, you need tools, and they need to work at the body level, not just the mind. Here's what I actually recommend, and share with my clients going through a break up:

1) The Reality Reel: Recall, Visualize, Feel It

This is the most powerful one and the one most people skip because it feels uncomfortable. And trust me when I say, I know it's not easy to shift our thinking to remember tough times when we're stuck in the loop of "all the great things they did.". Here is what you're going to do: When you catch yourself romanticizing, think of a specific memory of a time your ex did something that hurt you, dismissed you, made you feel small, or left you confused. Don't just think about it, visualize it. See their face. Notice where you felt it in your body. Let the discomfort be there for a moment. This isn't about making them the villain. It's about giving your nervous system the complete picture, not just the edited version. Remember, your brain has been running a highlight reel. This is how you add the deleted scenes back in.

2) What Would You Tell Your Best Friend?

Genuinely, if your closest friend described this relationship to you from the outside, what would you tell her? If you really kept It real and didn't to protect her feelings. What would you actually say? We are often dramatically more clear about other people's situations than our own. This is because we aren't in a grief response about their relationship. Use that clarity. Write out what you'd tell her. Then read it as if it were written to you. This exercise creates what researchers call self-distancing, a shift in perspective that reduces emotional reactivity and increases access to your own wisdom.⁴

3) Write the Unedited Version

Get out a piece of paper (not the notepad on your phone, actual pen & paper) and write out the relationship as if you were a journalist, not a grieving ex. What actually happened? Not what you wish had happened. Not the story you've been telling. The facts. The patterns. The things you noticed but explained away. Be sure to "check the facts" as I like to say to my clients. Can this statement be proved In a court of law, or Is It you're narrative.

4) Feel What You've Been Avoiding

If we look at this through an Internal Family System (IFS) lens: There Is a part of you that keeps reaching for the highlight reel and that's not because this part wants to hurt you--- it's a protector. It's doing its job, keeping you from feeling something that once felt too big to hold.

I know as humans we don't like to feel discomfort, but like I always say: "you have to feel to get to the other side."

Here's the truth about positive memory bias: sometimes the brain reaches for romanticization not because the relationship was actually great, but because the grief underneath it is too uncomfortable to sit with. The missing them is easier than the other feelings: the anger, the humiliation, the grief of what you wanted it to be and it wasn't.

If you find that these feelings spike, especially at night, or when you're stressed, or when life feels uncertain-- that's your nervous system seeking a familiar comfort. The work isn't to stop missing them. It's to turn toward what's underneath the missing. That's where the real healing is.

5) Create a Pattern Interrupt

When the 11pm spiral hits, have a physical anchor ready. Not a distraction (doom scrolling, drinking, texting someone you don't actually like-- put that phone down, girl!). A genuine pattern interrupt: get up, change rooms, put cold water on your face. Then place your hand on your heart and say out loud: "a part of me is trying to protect me from feeling this pain, and I'm safe now." The goal isn't to suppress the feeling. It's to create just enough space between the trigger and the spiral to choose differently. Regulate first. Process second.

A Note on the Parts of You That Still Miss Them

I want to be honest with you about something. Even doing all of this, there will still be a part of you that misses them. That part is real. It's not delusional or weak, it's a part of you that experienced genuine connection, genuine love, genuine hope. It deserves compassion, not judgment.

The goal of this work isn't to make yourself feel nothing. It's to stop letting one edited, grief-saturated version of the story be the only voice in the room. You can hold space for the part that misses them AND give yourself back the full picture at the same time.

That's what anchoring in reality actually means. Not hardness. Wholeness.
