Forgiving an Unfaithful Ex: Why Letting Go Is About Your Healing, Not Their Redemption

This week after winning an Olympic bronze medal, Norwegian Skier, Sturla Holm Laegreid said in an emotional interview “There is someone I wanted to share this moment with who may not be watching today. Six months ago I met the love of my life, the most beautiful and kindest person in the world. Three months ago I made my biggest mistake and cheated on her, and I told her acharlo week ago. It has been the worst week of my life.” in this article we discuss if his girlfriend should forgive him and what that really means. 

Few experiences cut as deeply as being betrayed by someone you trusted. Infidelity can leave people wrestling with anger, grief, humiliation and self-doubt — emotions that don’t simply disappear once the relationship ends. Yet, while forgiveness can sound like an impossible ask, psychology and lived experience suggest that forgiving an unfaithful ex is less about absolving them and far more about protecting your own mental health.

Importantly, forgiveness does not mean excusing what happened. It doesn’t require reconciliation, friendship, or even a conversation. Instead, it’s a conscious decision to stop allowing someone else’s actions to occupy emotional space in your life.

A recent sports story illustrates just how complex betrayal and forgiveness can be. During the 2026 Winter Olympics, Norwegian biathlete Sturla Holm Lægreid shocked audiences by tearfully confessing in a live interview that he had cheated on his partner, describing it as “the biggest mistake of my life.”

He publicly expressed regret and hoped for another chance, saying he could not “live [his] whole life keeping it a secret.”

But his former girlfriend made clear that forgiveness was not automatic, responding that “it’s hard to forgive… even after a declaration of love in front of the whole world.” 

The story sparked global conversation precisely because it highlights a truth many people know privately: the person who caused the hurt may seek forgiveness, but the injured party must decide what healing looks like for them — and that may or may not include granting it.

Forgiveness Is an Internal Process, Not a Social Contract

One of the biggest misconceptions about forgiveness is that it’s something you give to someone else. In reality, forgiveness is something you do for yourself. Holding onto resentment can keep your nervous system locked in a state of stress, replaying events and fuelling rumination. Letting go interrupts that cycle.

In the Olympic case, Lægreid’s emotional confession became a public spectacle, but critics noted the timing shifted attention away from the sporting achievement itself and raised questions about whether such personal matters should be processed privately. ()
That tension mirrors what happens after betrayal: healing is rarely helped by drama, explanation, or grand gestures. It’s usually quieter, slower, and deeply personal.

You Can Forgive Without Reopening the Door

Forgiveness is often confused with reconciliation. They are not the same.

Reconciliation requires:

  • rebuilt trust
  • mutual accountability
  • and a desire to continue the relationship.

Forgiveness requires none of these. You can forgive someone and still:

  • maintain strict boundaries
  • choose no contact
  • end the relationship permanently
  • or decide they no longer have a role in your life.

The athlete’s former partner underscored this distinction by expressing pain and reluctance to forgive despite his public remorse. Her response reflects a healthy reality: forgiveness cannot be demanded, accelerated, or performed for appearances.

Letting Go Helps You Reclaim Control

Infidelity often creates a sense of powerlessness — as though someone else rewrote your story without consent. Forgiveness, when you’re ready, is a way of taking authorship back.

It shifts the focus from:

  • Why did they do this?
    to:
  • What do I need to move forward?

That shift can reduce emotional exhaustion, improve clarity, and allow space for new relationships that aren’t overshadowed by unresolved pain.

Forgiveness Is Not a Single Moment

Despite the cultural narrative of dramatic apologies and clean resolutions, forgiveness is rarely instantaneous. It’s usually gradual — a series of choices to stop revisiting the wound.

Even in the public Olympic saga, the aftermath showed no neat ending, only complicated emotions, regret, and uncertainty about what comes next. ()
That lack of closure is, in many ways, the most relatable part.

The Takeaway: Forgiveness Is Self-Respect in Action

Forgiving an unfaithful ex doesn’t mean:

  • saying what they did was acceptable
  • welcoming them back into your life
  • or pretending the betrayal didn’t matter.

It means deciding their behaviour no longer gets to shape your emotional future.

Forgiveness, at its healthiest, is not about restoring the relationship — it’s about restoring yourself. If you would like to explore the topic of forgiveness with other separated people who get it join a Restored Lives course.
