Ever feel like your brain is a broken record? You’re trying to sleep, but instead, you're replaying a conversation from 2019 with someone who isn't even in your life anymore. It’s exhausting. Learning how to forget people isn’t actually about a literal lobotomy or magic amnesia; it’s about reducing the emotional "charge" attached to a memory until it stops ruining your Tuesday.
Memory is sticky. Neuroscientists like Dr. Elizabeth Loftus have spent decades proving that our brains don't just record things like a camera; we reconstruct them. Every time you pull up a memory of an ex or a former friend, you’re basically re-saving the file, often with more emotional weight than the last time. It’s a loop.
Stop trying to force it. The more you tell yourself "don't think about the purple elephant," the more you see the elephant. Honestly, the first step in how to forget people is accepting that for a while, you're going to remember them. A lot.
The Science of Why We Can't Just Hit Delete
The human brain is hardwired for attachment. We’re social animals. When we lose someone—whether through a breakup, a falling out, or a death—the brain processes that social rejection in the same areas it processes physical pain. The anterior cingulate cortex lights up like a Christmas tree. It’s literally "hurting."
So, why do they stay in your head?
Blame the Zeigarnik Effect. This is a psychological phenomenon where our brains remember uncompleted or interrupted tasks better than completed ones. If a relationship ended without "closure" (whatever that actually means), your brain treats it as an open loop. It keeps bringing the person up because it wants to resolve the story.
You’re basically stuck in a mental "loading" screen.
Biology plays a role too. If you were close to this person, you likely had high levels of oxytocin and dopamine associated with them. Now, you’re in withdrawal. It’s a chemical crash. You aren't just missing a person; you're missing the neurochemical cocktail they provided.
The Myth of Closure
People obsess over closure. They think one last conversation or a final "honest" email will fix it. It rarely does. In fact, seeking closure often keeps you tethered to the person even longer. You're waiting for them to give you permission to move on.

Don't do that.
True closure is something you manufacture yourself. It's a solo project. You decide the story is over because you’re tired of reading it, not because the other person finally apologized. They probably won't apologize anyway. People are messy.
Practical Strategies for Mental Space
If you want to know how to forget people in a digital age, you have to start with the hardware. Your phone.
Muting is your best friend. You don't necessarily have to block them—though that works wonders—but you have to stop the "micro-dosing" of their presence. Every time you see their name on a Venmo feed or an Instagram story, you reset your recovery clock. It’s a tiny hit of dopamine followed by a massive crash.
Clean your digital house.
- Archive the chats so you don't see their face every time you open WhatsApp.
- Change their name in your contacts to something neutral or "Do Not Call."
- Delete the photos. Or at least move them to a hidden folder you can't access easily.
- Avoid "pain shopping"—which is when you intentionally look at their social media just to see what they're up to, even though you know it will hurt.
We've all been there. You're lying in bed, it's 11 PM, and you think, "I'll just see if they're still dating that guy." Two hours later, you're looking at their new boyfriend's sister's vacation photos from 2022. Stop. It’s self-sabotage.
Environmental Cues and Sensory Anchors
Our memories are tied to our environment. If you always sat in that one chair to talk to them, that chair is now a trigger. If a certain perfume or song reminds you of them, your brain is using "associative learning."
To break this, you need to create "interference."

Interference is a real psychological term. Proactive interference happens when old memories interfere with new ones, but you can use retroactive interference to your advantage. Start making new memories in those same spots. Go to that coffee shop with a different friend. Listen to that song while doing something totally unrelated, like cleaning the bathroom. You’re overwriting the old emotional data with boring, new data.
Forgetting is a Form of Forgiveness (Mostly for Yourself)
There's this quote often attributed to various philosophers about how holding a grudge is like drinking poison and waiting for the other person to die. It’s cliché because it’s true. When you can’t forget someone, it’s often because you’re holding onto the anger of how they treated you.
Anger is an attachment.
If you hate someone, you’re still connected to them. Indifference is the goal. You want to get to the point where you see their name and feel... nothing. Just a flat "oh, yeah, that person."
How do you get there?
By focusing on the "Self-Expansion Model." This is a theory by psychologist Dr. Arthur Aron. It suggests that in close relationships, our identities merge. When the relationship ends, you lose a piece of yourself. To "forget" them, you have to find those lost pieces or build new ones. You need to expand your identity until they are just a tiny, insignificant dot in your past, rather than the horizon you're looking at.
The Role of Rumination
Rumination is the enemy. It’s that repetitive, circular thinking that leads nowhere.
If you catch yourself ruminating, use the "Stop" technique. Literally say the word "Stop" out loud. It sounds silly, but it breaks the neural loop for a split second. Then, immediately engage in a high-cognition task. Crossword puzzles, learning a new language on an app, or even just counting backward from 100 by sevens ($100, 93, 86...$).

Your brain can't easily ruminate on an ex while also doing complex math. It’s a hardware limitation. Use it.
When Memory Becomes Intrusive
Sometimes, the inability to forget isn't just a "breakup" thing; it can be a symptom of something deeper, like Post-Traumatic Stress Disorder (PTSD) or what some call "Complex PTSD" from long-term toxic relationships. If the memories are accompanied by panic attacks, flashbacks, or a total inability to function, standard advice won't cut it.
In these cases, therapies like EMDR (Eye Movement Desensitization and Reprocessing) are incredibly effective. EMDR helps the brain "reprocess" traumatic memories so they are stored as regular, non-threatening memories rather than active threats.
It’s basically professional-grade how to forget people (or at least, forget the pain they caused).
The Long Game: Building a New Narrative
You're never going to truly "forget" a person who was a major part of your life. The goal is to change the meaning of the memory.
Instead of "The person who broke my heart and ruined my life," the story becomes "The person who taught me I have boundaries" or "The person I used to know before I became who I am now."
Shift the focus from them to you.
- Audit your daily routine. Where are the "memory leaks"? If you spend your morning commute thinking about them, change your route or start a new podcast that requires your full attention.
- Externalize the thoughts. Write a "burn letter." Write down every single thing you want to say to them. Get it all out. Then, destroy the letter. Do not send it. The act of writing moves the thoughts from your internal "RAM" to a physical medium, which helps the brain let go.
- Invest in "Social Capital." Reach out to the people who are there. Rebuilding your other social circles reminds your brain that your survival and happiness aren't dependent on that one missing person.
- Practice Mindfulness. Not the "sit on a pillow and float" kind, but the "stay in the room" kind. When you feel a memory coming on, ground yourself. What do you see? What do you smell? What does the floor feel like under your feet?
It takes time. It’s frustratingly slow. You’ll have days where you think you’re over it, and then a random smell of rain or a specific brand of cereal will bring it all back. That’s okay. Recovery isn't a straight line; it's a messy spiral that eventually trends upward.
Stop checking their "Last Seen" status. Stop asking mutual friends how they are. Basically, stop feeding the ghost. If you stop giving the memory attention, it will eventually starve. It won't disappear, but it will get very, very quiet. And quiet is enough.
Start today by deleting one thing. A photo, a contact, a saved voicemail. Just one. That’s how the process starts. It isn't a giant leap; it’s a series of tiny, intentional choices to live in the present instead of a past that no longer exists.
