There is a strange comfort we take in believing that sexual betrayal belongs to other people. Other marriages. Other kinds of men. Other kinds of women. We imagine it happens to couples who “let themselves go,” or to naive spouses who ignored obvious red flags, or in glamorous circles where temptation is everywhere — anywhere, really, other than in beds like ours.

But infidelity has no postcode.

It happens in council estates and country estates. It has rocked palaces and parsonages, locker rooms and boardrooms, retirement villages and university campuses. The pastor’s wife discovers the messages. The CEO’s husband finds the hotel receipts. The young bride, the devoted husband of forty years, the celebrity, the schoolteacher, the royal — sexual betrayal does not check your income, your age, your faith, or your virtue at the door. The duchess and the dinner lady can be shattered by precisely the same discovery, on an ordinary day that started like any other.

And yet, when it happens, society reaches instinctively for judgement.

She must have stopped trying. He clearly wasn’t meeting her needs. What did she expect, marrying a man like that? There are always two sides — what was going on at home?

The betrayed partner, already bleeding, is quietly put on trial. And the unfaithful one is either cartoonishly demonised or casually excused, depending on who’s telling the story. We judge because judgement feels safer than understanding. If affairs only happen to flawed people in flawed marriages, then we can convince ourselves our own relationship is immune. But no relationship is immune. And our judgments reveal something deeper: we don’t actually understand what is driving this epidemic. We keep diagnosing the rash while ignoring the illness.

The Thing That’s Missing

Here is what sits underneath it all: an almost universal absence of true unconditional love.

Before you nod along too quickly — because most of us believe we already give it — sit with that phrase. Unconditional love. Love without terms. Love that doesn’t keep score. Love that isn’t quietly transactional, isn’t contingent on being desired, admired, agreed with, or made comfortable.

Most of what we call love is actually conditional, and we don’t even notice. We love our partners when they make us feel good about ourselves. We love them as long as they stay attractive, successful, attentive. We love them until they disappoint us, bore us, or stop reflecting back the version of ourselves we want to see. The conditions are so woven into how we relate that we mistake them for love itself. Most marriages are not two people loving each other at all — they are two people trading, each keeping a silent ledger, each starving.

And here’s the other great misunderstanding: many people hear “unconditional love” and picture a doormat. The wife who stays through affair after affair. The husband who forgives instantly and asks no questions. They dismiss unconditional love as naive, unsustainable, even dangerous — a licence for the unfaithful to keep wounding.

But that is not what it is. And this is where the modern answer fails us so badly. The therapy world hands everyone the word boundaries — draw your boundaries, enforce your boundaries, protect yourself with boundaries. But look closely and a boundary is just a wall with better branding. Walls are built to control — to fence another person’s behaviour, to manage them from behind a barricade. You cannot love someone through a wall, and no one has ever been inspired to become more by one.

Unconditional love doesn’t build walls. It holds standards—and standards do something walls never can: they invite people to rise.

A standard says: I love you without conditions, and I hold a standard for how I will be treated and what I will live alongside. I will not share you. I will not live inside your lies. And I believe you are capable of more than this. A wall keeps someone out; a standard calls someone up. Real unconditional love holds the highest standards of all — because it includes loving yourself without conditions too. The spouse who endlessly absorbs betrayal isn’t practising unconditional love; they are practising fear, and hoping it will be mistaken for devotion. They have abandoned their standards, and in doing so they invite no one to rise — not their partner, and not themselves. And the one who demands endless forgiveness while changing nothing isn’t asking for love — they’re asking for a hiding place.

The Soul’s Substitutes

Our souls crave unconditional love the way our bodies crave water. It is not a romantic luxury — it is the foundation we were meant to be built on. And when it’s absent, as it so often is, the soul doesn’t simply go without. It seeks substitutes.

This is what almost no one wants to say about infidelity: the affair is not about the affair. It is a painkiller. The rush of being newly desired, the secrecy, the fantasy of being truly seen by a stranger who hasn’t yet found your flaws — these are counterfeit versions of the very thing the soul has been starving for, often since childhood. People who were only ever loved for performing — for achieving, pleasing, being good, being attractive — grow into adults with a hollow space where unconditional love should live. And that hollow space is hungry.

Pornography, serial affairs, secret entanglements, the thrill of flirtation and conquest — these are not random moral failures. They are the soul’s desperate attempts to bury a pain it cannot name: I have never been loved without conditions, I do not believe I am lovable as I actually am, and I don’t know how to love that way either.

This doesn’t excuse betrayal. Let me be unmistakably clear: sexual betrayal is devastating. Anyone who has lived through discovery day knows it tears through a life like an earthquake — the ground you stood on simply isn’t there anymore. The betrayed deserve fierce compassion, truth, and justice. But if we want to understand why this keeps happening — across every demographic, in every generation — we have to look at the emptiness, not just the act. Betrayal is born not from evil, but from a starving soul reaching for a substitute and willing to burn down something real for a moment of counterfeit relief.

Treating Symptoms, Not the Cause

Instead, look at what we do. An affair is discovered, and the whole machinery of symptom-management kicks in. Check their phone. Install the tracking app. Set the rules. Sit through the counselling sessions where everyone learns new vocabulary — attachment styles, communication tools, boundaries — and walks out having named everything and changed nothing. Or on the other side: leave, get the settlement, warn your friends, trust no one, guard your heart forever.

Some responses are necessary in the moment — safety and truth come first. But notice that almost none of them touch the cause. The unfaithful partner promises “never again” without ever asking what hollow space the affair was feeding. The betrayed partner is told to either forgive or leave, but rarely helped to face the deeper wound — or to see the conditional loving that may have been running silently in both directions for years, in the marriage and long before it. We manage behaviour. We never feed the famine.

And so it happens again. The same person cheats in the next relationship. The betrayed carries their armour into the next marriage and calls it wisdom. Children watch, absorb, and repeat. The wound gets passed down like an heirloom nobody asked for — because we keep treating the affair, and never the starvation beneath it.

Waking Up

So what would waking up actually look like?

It would look like recognising that the epidemic of infidelity — across every class, every culture, every age group — is not merely a character crisis or a “modern values” crisis. It is a love crisis. It would mean learning, perhaps for the first time in our lives, what unconditional love actually is: fierce, honest, free of scorekeeping, and held to the highest of standards. It would mean offering it first to ourselves — because the person who knows, in their bones, that they are loved and lovable as they are does not need the painkiller of an affair, and does not confuse enduring a broken marriage in silence with virtue. It would mean raising children whose worth is never up for negotiation, so they don’t grow into adults trying to fill the hollow space in hotel rooms and hidden message threads. It would mean telling the unfaithful the whole truth — that what they did caused devastation, and that they are capable of rising to something far greater — because punishment alone has never once cured this, in all of human history. Walls have never transformed anyone. Standards, held in love, have transformed millions.

Sexual betrayal knows no bounds. It has reached every address, every age, every rank of society, from the poorest streets to the throne itself.

But so can love — the real kind. The kind almost none of us were given, and almost none of us have learned to give. The kind that holds a standard and says: rise.

The question is which one we’re going to keep feeding.
