Is it Ever Okay to Keep Secrets from Your Spouse?

Shortly after Daniel and I got married, we had dinner with a couple we were semi-friends with. They were a little older than us, had been married longer and already had small children.

Somehow, the conversation turned to infidelity. The wife casually shared an agreement she and her husband had made: If one of them ever kissed someone else, crossed a line or made some one-time mistake, but knew they had no intention of leaving the marriage or pursuing the other person, they wouldn't tell each other.

Her reasoning was simple. People make mistakes. Why burden your spouse with an image or insecurity they might carry for the rest of the marriage if the mistake was over and the marriage was never in question?

I remember sitting there thinking, Wait. What?

That conversation happened more than a decade ago, and I still think about it.

Admittedly, I may not be the best person to ask. My team regularly reminds me that I am an extremely transparent person. I don't know how to operate any other way. To me, honesty and trust are foundational to a strong marriage.

But that dinner raised a question I've heard couples wrestle with many times since:

Does loving someone mean telling them everything?

Relationship research offers a surprisingly nuanced answer.

Research by psychologist Jean-Philippe Laurenceau and colleagues found that self-disclosure, particularly emotional disclosure met with a responsive partner, is an important part of intimacy. We grow closer when we allow ourselves to be known and when the person we love responds with understanding and care.

Secrets can also carry a cost. Psychologist Michael Slepian has studied thousands of real-life secrets and found that much of their burden comes not from actively hiding them, but from repeatedly thinking about them. Secrets we continually revisit in our minds are associated with lower well-being, authenticity and relationship satisfaction.

But the research also complicates the idea that every undisclosed truth automatically damages a relationship.

A 2023 longitudinal study of 609 adults keeping significant secrets from romantic partners found that people in less satisfying, less trusting relationships tended to be more preoccupied with their secrets. But researchers did not find evidence that thinking about the secret itself caused the relationship to deteriorate over time.

Sometimes secrecy may reflect a relationship already struggling with trust rather than being the sole cause of that struggle.

And then there's an important distinction: privacy and secrecy are not necessarily the same thing.

The late communication researcher Sandra Petronio spent decades studying how people manage private information. Her work suggests that healthy relationships constantly negotiate a balance between openness and individuality.

Marriage joins two lives, but it doesn't erase personhood. A healthy spouse can still have private thoughts, conversations, memories and moments that belong to them.

Esther Perel makes a similar distinction. She has argued that healthy intimacy requires some room for privacy while also warning that secrecy can become destructive.

When asked whether someone should always disclose an affair, Perel resists making one universal rule. Instead, she encourages people to consider the couple, the circumstances and the consequences of both telling and remaining silent.

She also asks an uncomfortable but worthwhile question: Who is the confession serving?

Sometimes telling the truth is an act of accountability and a necessary step toward restoring trust. But Perel suggests there are situations where confession may primarily relieve the guilty person's conscience while transferring the emotional burden to the innocent spouse.

Other relationship experts place greater emphasis on full transparency.

In the Gottman approach to recovering from infidelity, honesty, accountability and disclosure are essential to rebuilding trust. A betrayed spouse needs enough truth to understand what happened and make informed decisions about the future of the relationship, though the Gottman’s generally caution against sharing unnecessarily graphic details.

I think this is where personal responsibility becomes especially important.

Grace matters in marriage. People fail. People act selfishly. Good people sometimes make bad decisions. Strong relationships make room for repentance, forgiveness and growth.

But grace is not the same thing as avoiding consequences.

So perhaps instead of asking only, Do I have to tell my spouse?, we should ask better questions:

Does this information affect my spouse's ability to make informed decisions?

If a secret affects sexual health, finances, family stability, safety or the basic terms of the relationship, withholding it becomes much harder to defend as simple privacy.

Am I protecting my spouse or protecting myself?

"I don't want to hurt them" can come from compassion. It can also be a convenient way to avoid accountability.

What will keeping this secret require next? There is a difference between keeping a private thought and creating an ongoing pattern of deleted messages, hidden spending, altered stories or deception.

And perhaps most importantly: What promises have we made to each other?

This is where I keep coming back to that couple from years ago.

I wouldn't choose their agreement. But they had actually talked about it. They had decided together what they considered a betrayal, what they wanted disclosed and what they didn't.

Maybe that's the conversation more couples should have before they're standing in the middle of a crisis.

What does faithfulness mean to us? What do we consider private? What would we absolutely want to know? What boundaries protect our relationship? And what responsibility do we owe one another when we fail?

More than a decade later, I'm still not sure I could live comfortably with my friends' arrangement. For me, honesty is deeply connected to trust, and trust is deeply connected to commitment.

But I'm also less convinced that loving someone gives us a right to every thought, memory or private corner of their inner world.

Every couple will ultimately have to decide where that line sits.

Maybe the most important question isn't simply, Am I keeping a secret?

Maybe it's this:

Am I protecting something that reasonably belongs to me, or am I withholding something my spouse has a right to know because the truth might require me to take responsibility for what I've done?

That distinction is worth thinking about before the answer ever becomes necessary.
