Inside the Mind of the Unfaithful: Why We Lied, and How We Finally Stop

Editor's Note: For the unfaithful spouse, the cycle of lying often begins long before the infidelity itself. In today's post, an unfaithful spouse shares her personal journey of untangling a lifetime of deception, facing her deepest fears of rejection, and doing the agonizing—but necessary—work of pulling the truth into the light.

"Liar." "Cheater."

Just reading those words probably makes your stomach drop. I know the feeling. It’s a sickening, heavy sensation that makes you want to bury your head and hide. When you are the one wearing those labels, the spiral of shame can feel like drowning. You don't have the strength to face the reality of your brokenness without also knowing that redemption is possible.

If you are an unfaithful spouse, I know where you are sitting. And I know you have to accept the possibility for change and repentance, or that shame will swallow you whole.

So, how did we get here?

Swimming in the Water of Deception

It’s hard to look back on my life and pinpoint the exact moment I started choosing lies over the truth. Like water is to a fish, dishonesty was just something I lived with.

That might sound strange to some, but a better way to explain it is that I was always living with fear. I was terrified that the truth was inherently ugly. I didn't see much repentance, acceptance, or forgiveness in my family of origin, so I learned early on to protect myself.

I remember being in first grade. I had a harsh, strict teacher who clicked her heels when she walked—she was the opposite of warm and nurturing. One day, out of pure boredom, I started doodling on the corner of my desk with a pencil. When my teacher caught me, I was immediately sent to the office. She wrote a note for me to give to my parents and assigned me to write "I WILL NOT WRITE ON MY DESK" 100 times.

It took me almost a week to hand that note to my parents. I was terrified, and I hated my teacher for exposing me.

To cope, I justified it. What’s the big deal? I can erase it. It’s just pencil. Justification became my defense mechanism of choice. My deeply defensive heart didn't start with infidelity; it started in first grade.

Why We Choose the Lie

Is this sin and shame inherent to my nature? Partly, yes. There is a deeply selfish, stubborn part of me that wants to point the finger and avoid responsibility.

Lying is wrong, and anyone who has ever been betrayed can testify to how thoroughly deception destroys a relationship. But here is the hard truth about the unfaithful heart: being told I was wrong was never a good motivator for me to change. In fact, it only deepened my resolve to bury and hide the guilt I felt.

What I desperately needed—but felt I didn't deserve—was acceptance and understanding. When I finally began to understand that my lying came from a place of deep-seated fear, the lights came on. I was terrified of conflict, afraid of losing people, and paralyzed by the thought of losing acceptance. Deep down, I wanted to be honest, but I never figured out how to do it—until Affair Recovery. It was just easier to lie.

Or so I thought.

The Cost of Hiding

I told myself my lies were keeping me safe. In reality, my lying kept me distant, unavailable, and hollow. Yes, my dishonesty devastated my husband and almost cost us our marriage, but it also completely crippled my own ability to be intimate.

Rehabilitation is possible. I am living proof of it. But it requires walking through the fire.

Telling my husband the entire, unfiltered truth about my infidelity and my past was the most difficult thing I have ever done. Working with a counselor to uncover those childhood defense mechanisms felt like pulling a rope of thorns and needles out of my chest, through my throat, and into the open air. It was agonizing.

But it was necessary.

What is not spoken, cannot be healed.

Choose Honesty

If you are the betrayed spouse reading this: you did not deserve to be lied to. On behalf of every unfaithful person out there, including me, we had no right to transfer our junk, our fear, and our shame onto you.

But if you are the liar reading this: choose reform. Stop justifying the pencil on the desk. Stop letting the fear of rejection dictate your life. Dig deep and figure out the sickness and the root of your deception. Do I still get the urge to lie today? Sometimes. I'll catch myself wanting to exaggerate or omit a detail to avoid a perceived rejection from my husband. But I aim to push through and share it anyway.

And that icky, heavy feeling in my chest? It always disappears the second the truth is spoken. You can breathe again. But first, you have to choose honesty.
