Why do I feel guilty for outgrowing a friend?

I’ve been asking myself this for a while, and I want to actually think it through.

You know the feeling. There’s someone who used to be your person. You knew their family, their exes, their coffee order, the exact face they make right before they cry. For years, they were the first one you texted about anything. And now you’re… not really friends. Not officially.

There was no fight. Nobody did anything wrong. You just slowly ran out of things to say. You meet up, and it’s nice, and it’s also a bit like visiting a house you used to live in. Everything’s where you left it, and you don’t belong there anymore.

So you reply later. You say “we should catch up soon!” and you both know you won’t. And every time, there’s this small, annoying sting of guilt.

So why do I feel guilty about something I didn’t actually do wrong?

My first honest answer, the 4am one, is pretty unflattering.

Maybe I feel guilty because I am a bit guilty. Maybe I got a new job, a new city, new people, and decided the old ones weren’t interesting enough anymore. Maybe I’m just someone who moves on, and “moving on” is a polite way of saying leaving.

That answer feels true in the moment. But it also feels too easy. Like the kind of thing you tell yourself so you can feel bad and do nothing. So I wanted to check it against people who’ve thought about friendship much harder than I have.

The first person I went to was Aristotle, because he wrote more about friendship than almost anyone: two whole books of the Nicomachean Ethics. And the first thing he does is quietly let you off the hook.

He says most friendships are built on one of two things: pleasure, because you have fun together, or usefulness, because you get something out of each other: a flatmate, a study buddy, someone to go out with. And those friendships, he says, naturally end when people change. Not because anyone’s a monster, but because the thing that held them together isn’t there anymore. He even says young people’s friendships change especially fast, because young people change so fast.

Reading that, I felt relieved for about five seconds. Then I thought: okay, but what about the ones that weren’t just fun or useful? What about the friend who really knew me?

Aristotle has an answer for that too, and it’s the part I keep coming back to. He imagines exactly this situation: one friend changes a lot, the other doesn’t, and they can’t be friends the way they were. Do you just treat them like a stranger now? No, he says. You should keep “a remembrance of our former intimacy” and make “some allowance for our former friendship.”

So according to Aristotle, I’m not obliged to keep the friendship going. But I’m also not allowed to pretend it never happened.

I don’t owe them the future. I owe them the past.

Which is helpful. But it still doesn’t explain the guilt. If I haven’t done anything wrong, why does it feel like I have?

That’s where Nietzsche comes in, because he went through exactly this. And he didn’t outgrow just anyone. He outgrew his hero.

In 1868, Nietzsche was a 24-year-old classics student who got invited to meet Richard Wagner, the most famous and most argued-about composer in Europe. Imagine meeting the artist you’re obsessed with, and they actually like you back. That’s what happened. They bonded over Schopenhauer, Wagner invited him to visit, and when Nietzsche got a job teaching in Basel, he realised Wagner’s house on Lake Lucerne was a short trip away.

So he went. Over and over. More than twenty visits in three years. He spent Christmas there. He ran errands for Wagner and his partner Cosima. His first book opens with a dedication to Wagner that reads like a love letter. He was basically family.

And then Nietzsche started changing. He got more sceptical, more independent, less interested in worshipping anybody. Meanwhile, Wagner was becoming a national monument. In 1876, Nietzsche went to the first festival at Bayreuth, the huge theatre Wagner had built for his own operas, and he hated it. The crowds, the nationalism, the rich people who were there to be seen. He left early. That autumn they met in Sorrento. It was the last time they ever saw each other.

Nobody slammed a door. They just went in different directions.

Honestly, this is the part that gets me, because it’s so recognisable. There was no betrayal. Nietzsche just became someone who didn’t fit inside that friendship anymore. And it still mattered so much that he wrote about it for the rest of his life.

The most beautiful thing he wrote about it is a short passage in The Gay Science (1882) called “Star Friendship.” It doesn’t name Wagner, but everyone knows who it’s about. It starts:

“We were friends, and have become strangers to each other. But this is as it ought to be, and we do not want either to conceal or obscure the fact, as if we had to be ashamed of it.”

I’ve read that sentence maybe fifty times. It’s the complete opposite of my 4am answer. As it ought to be. Not “sadly.” Not “because I failed.” He’s saying that drifting apart can be the friendship doing exactly what it was supposed to do.

Then he says the two of them are like two ships. For a while they were in the same harbour, and it looked like they were heading for the same place. But each ship has its own course, and the courses pulled them apart. And above all that, he imagines a huge, invisible orbit, like the paths of the stars, where their very different lives might still be part of the same story. So, he says, let’s believe in our star friendship, even if down here we have to be strangers.

I love that so much. It turns “I left” into “we both kept going.”

But I also don’t completely believe him. Or rather, I believe him, and I notice something. If it really was “as it ought to be,” why did he never stop writing about it? Years later, near the end of his life, he wrote that he’d happily give up almost every other relationship he’d ever had, but not those days at Wagner’s house. Not at any price.

So even Nietzsche, the man who told everyone to stop feeling guilty about everything, couldn’t quite let it go. Which brings me back to my question. If outgrowing someone isn’t wrong, why does it still hurt?

The answer that finally made sense to me came from someone I didn’t expect: Melanie Klein, a psychoanalyst who spent most of her career watching very small children play.

Klein was born in Vienna in 1882 and ended up in London, where her ideas basically split British psychoanalysis in two. She analysed kids as young as two or three, using toys instead of a couch. And what she saw in those tiny people wasn’t sweet. It was love and rage, often for the same person, sometimes within the same minute.

Her big idea goes roughly like this. At the very beginning, a baby can’t hold two feelings about one person. So it splits the world in half. There’s a “good” mother who feeds and comforts, and a “bad” mother who’s late, absent, or says no. The baby loves one and hates the other, and never connects the dots.

Then, slowly, it does. It realises the one it loves and the one it’s been furious with are the same person. And with that comes a completely new feeling: guilt. Worry that it might have hurt someone it loves. Sadness. And then a wish to make things better, which Klein called reparation.

She called this stage the depressive position, which sounds bleak, but for her it was an achievement. It’s the moment you stop seeing people as all good or all bad, and start seeing them as whole human beings. Guilt, in her view, is the price of growing up. And she thought we keep coming back to that moment for the rest of our lives, in every relationship that matters.

When I read that, something clicked.

Because maybe the guilt I feel about outgrowing a friend isn’t a verdict at all. Maybe it’s just what happens when you can see someone whole. Yes, they bore me a bit now. Yes, we don’t have much in common anymore. But they were also there when things fell apart, when I needed someone at 3am, when nobody else was. They’re not “the friend I grew out of.” They’re a full person, and part of me knows I’m capable of hurting them. That knowledge is exactly what guilt is.

So my 4am answer had it backwards.

The guilt isn’t proof that I’m a bad friend. It’s proof that I was a real one.

You don’t feel guilty about people who never mattered.

Klein’s work also helped me see that there are two kinds of guilt. One just goes round and round, making you feel terrible and changing nothing. The other turns into reparation: it makes you want to do something kind. Later in her life she added one more ingredient, gratitude: being able to feel glad for what someone gave you, without needing to keep them forever.

And this wasn’t just theory for her. Her own daughter, Melitta, also became a psychoanalyst, and then one of her mother’s fiercest public critics. They never made up. Klein knew exactly what it feels like when someone you love goes in a direction you can’t follow.

So, back to my question. Why do I feel guilty for outgrowing a friend?

Here’s where I’ve landed, at least for now.

I don’t feel guilty because I did something wrong. Aristotle’s right that most friendships are tied to a time and a place, and when those change, the friendship changes too. Nietzsche’s right that two people can just be on different courses, and that’s nothing to be ashamed of. Nobody gets a medal for staying exactly the same person they were at nineteen. Changing is kind of the whole point.

I feel guilty because they mattered. Klein’s right about that. The guilt is just love noticing that there’s a real person on the other end of the slow fade.

And once I see it that way, the question changes. It’s not “am I a bad person for drifting?” anymore. It’s “what do I do with this feeling?”

I think there are two bad options. One is to keep pretending: sending “we should catch up!” forever, faking a closeness that isn’t there, because ending the pretence feels too cruel. Nietzsche would hate that. The other is to let it disappear in total silence, as if those years never happened. Aristotle would hate that.

What’s left in the middle is something like Klein’s reparation, and honestly it’s smaller than it sounds. It’s not forcing the friendship back to life. It’s a message that says “I was thinking about you, and I’m really grateful for those years.” It’s actually showing up for the wedding, or the birthday, or the bad news. It’s telling someone else a story about them and smiling. It’s keeping, as Aristotle put it, a remembrance of the former intimacy.

I don’t owe anyone the rest of my life. But I probably owe a few people a thank you. For the flat, the nights out, the 3am phone calls, for being my person when I needed one.

Some friendships are for life. Some are for a chapter. I’m starting to think both count.

And maybe Nietzsche was right about the stars after all.

Two ships, different courses. But somewhere up there, still part of the same story.

“Some friendships are for life. Some are for a chapter. Both count.”
