It happens in the grocery store aisle or while you're scrolling through a generic playlist on a Tuesday afternoon. A specific scent, a chord progression, or even the way the light hits the pavement, and suddenly, that person is back in your head. You thought you were done. You’ve done the work, deleted the photos, and maybe even moved cities. Yet, the internal monologue starts up again: you still get to me.
Why?
It isn't just about "not being over it" in the way pop songs describe. It’s actually a complex cocktail of neurobiology, cognitive loops, and how our brains encode high-stakes emotional memories. We often feel guilty about it. We think it means we're weak or that our current life isn't "enough." Honestly, that's rarely the case. The brain doesn't just delete files because they're old. It archives them in high-definition if they were once vital to our survival or identity.
The Science of Emotional Echoes
The human brain is an incredible machine, but it’s kinda terrible at distinguishing between a past threat or joy and a present one when a trigger is pulled. When you feel that "you still get to me" sensation, your amygdala is likely doing the talking. This almond-shaped cluster is responsible for processing emotions.
Research by neuroscientists like Dr. Joseph LeDoux has shown that emotional memories formed in the amygdala are remarkably persistent. While your conscious "explicit" memory (the part that remembers your grocery list) might fade, the "implicit" emotional memory remains. It’s why you can forget someone’s middle name but still feel your stomach drop when you see a car that looks like theirs.
We also have to talk about dopamine loops.
If a relationship was intense—whether it was toxic or just deeply passionate—it likely created a reward circuit in your brain similar to an addiction. When that person "gets to you," it’s often your brain looking for a hit of that old intensity. It’s not necessarily about wanting the person back; it’s about the brain remembering the feeling of being that alive, that hurt, or that seen.
Why the "No Contact" Rule Doesn't Always Kill the Feeling
You’ve seen the advice everywhere. Block them. Move on. Go "no contact."
And look, it works for logistics. It stops the new drama. But "no contact" is a physical boundary, not a mental delete button. You can be five years into a new, healthy relationship and still find that a specific person from your past has a weirdly high clearance level in your psyche.
The psychological concept of Unfinished Business, often discussed in Gestalt therapy, suggests that we struggle most with people who left us with unanswered questions. If a situation didn't have a clean ending—and let’s be real, almost nothing in real life has a cinematic "ending"—the brain keeps the file open. It’s trying to solve a puzzle that has no pieces left.
Sometimes, they still get to you because they represent a version of yourself that you’ve lost. Maybe you were more adventurous when you were with them. Maybe you were younger and felt the world was wider. When you think of them, you’re actually grieving the person you were in that era.
The Myth of Closure
We are obsessed with closure. We think if we just have one more conversation, or send one more perfectly worded text, the "you still get to me" feeling will evaporate.
It won't.
Closure is something you trade for peace. Expecting another person to provide the key to your mental exit is a trap. If they could have given you what you needed back then, they probably would have. Waiting for them to "fix" the feeling they cause is like asking a fire to be the water that puts it out.
Sociologist Tony Bilton and others have explored how modern "liquid love" and the fleeting nature of digital connections make this worse. We see bits and pieces of people on social media. We see a "like" or a "view" on a story. These tiny breadcrumbs keep the neural pathways active. They ensure the person stays "current" in our minds even if they haven't spoken a word to us in thirty months.
High Stakes and Trauma Bonding
We have to be honest about the darker side of this. If someone still gets to you in a way that feels heavy or restrictive, it might not be love. It might be a trauma bond.
In relationships characterized by intermittent reinforcement—where the "highs" are incredible and the "lows" are devastating—the brain becomes hyper-attuned to the other person. You become like a gambler at a slot machine. You’re waiting for the next win. Even years later, the ghost of that "win" can make your heart race. This isn't a sign of "soulmates." It's a sign of a nervous system that was pushed to its limit and hasn't quite come back down to baseline.
Shifting the Narrative
So, what do you do when the feeling hits?
First, stop pathologizing it. You aren't "crazy" for feeling a tug when an old flame's name comes up. You’re a human with a functioning memory.
Try to rename the feeling. Instead of saying "I'm still in love with them," try saying "My brain is currently visiting a very intense memory." It creates distance. It turns a permanent state of being into a temporary neurological event.
Think about the "Zeigarnik Effect." This is a psychological phenomenon where people remember uncompleted or interrupted tasks better than completed ones. If your relationship or friendship was cut short or ended abruptly, your brain is literally wired to keep thinking about it more than the relationships that ended naturally and slowly.
Actionable Insights for Moving Through the Feeling
If you find yourself stuck in a loop where someone from the past is dominating your mental space, there are practical ways to ground yourself. This isn't about "getting over it" overnight, but about reclaiming your focus.
1. Identify the "Persona," Not the Person When the thought hits, ask yourself: what quality does this person represent to me? Are they "adventure"? Are they "validation"? Are they "the one who got away"? Usually, we are missing a feeling, not the actual human being with their flaws, bad breath, and annoying habits. Once you identify the quality, look for ways to bring that into your current life without them.
2. The 90-Second Rule Neuroanatomist Jill Bolte Taylor suggests that the chemical surge of an emotion lasts about 90 seconds. If you can observe the "you still get to me" sensation without feeding it with new thoughts or checking their Instagram, the physical spike will pass. It’s the story we tell ourselves during those 90 seconds that keeps the loop going for hours.
3. Contextualize the Memory Our memories are liars. They perform "rosy retrospection," where we remember the highlights and edit out the reasons things didn't work. When a good memory hits, force yourself to remember a difficult one immediately after. Balance the scales. Remind your brain why that person is in the past category.
4. Audit Your Digital Environment If you are still "soft-following" them—muted but still checking—you are essentially poking a wound and wondering why it won't scar over. Use the "Out of Sight, Out of Mind" principle. It feels harsh, but your nervous system needs the quiet to recalibrate.
5. Rewrite the Ending Since you likely won't get a "final scene" with them, write it for yourself. Not a letter to them, but a statement of fact for you. "This was a chapter that taught me X, Y, and Z. It is now closed." Putting it into words helps the brain move the memory from "active/unresolved" to "archived/completed."
Ultimately, someone "getting to you" is just proof that you have the capacity for deep connection. It’s a trait, not a flaw. The goal isn't to become a robot who forgets everyone they’ve ever known. The goal is to be the person who can feel that old familiar tug, acknowledge it with a bit of a sigh or a smile, and then go right back to the life they're building in the present.
The past is a fine place to visit, but it's a terrible place to live. Take the lesson, leave the baggage, and keep your feet planted where you are right now.
