Monogamy, Cheating, and the Gap We Don't Talk About

A recent article in The Atlantic makes a simple but uncomfortable observation: most Americans believe cheating is wrong, and a lot of Americans cheat anyway.

That gap — between what we believe and what we actually do — is where things get interesting. And for many couples, where things fall apart.

At Pinnacle Counseling, we sit with that gap all the time.

The Ideal vs. The Reality

Monogamy is still the dominant expectation in relationships. For most people, it's not just a preference — it's a value. It represents commitment, trust, and the kind of stability people build a life around.

But we're also living in a world that quietly pulls in the opposite direction. We have more access to potential partners than ever before. There's enormous cultural pressure around personal growth and fulfillment. And relationships and marriages last longer than they did for previous generations.

Put simply, we're asking more of monogamy than we used to. And often, we're asking more of ourselves than we're really prepared to navigate.

Why People Cheat (It's More Complicated Than You Think)

When infidelity comes up, the instinct is usually to look for what went wrong in the relationship. Sometimes that's the right place to look. But it's rarely the whole story.

In our work, we see people cross that line for all kinds of reasons — a craving for novelty, feeling unseen over time, avoiding hard conversations at home, curiosity about parts of themselves they haven't explored. Often it's just opportunity meeting a lack of clear boundaries.

None of that excuses the behavior. But understanding it matters. Without that understanding, couples tend to stay stuck in blame instead of moving toward anything resembling repair.

The Hidden Problem: We Don't Actually Talk About This

Here's one of the most common dynamics we see: couples enter relationships with a shared assumption of lifelong monogamy, but without ever really talking about what that means. Not in a real way. Not beyond "we're committed."

But commitment raises a lot of questions that often go unspoken. What do you do when attraction to someone else shows up? How do you handle a stretch of disconnection? What actually counts as crossing a line — emotionally or physically? How do you talk about desire without it becoming a fight?

When those conversations never happen, couples are left to navigate high-stakes moments without any shared framework. That's usually where things break.

What Actually Strengthens Monogamy

If monogamy is something you value — and for many people, it genuinely is — the answer isn't pretending it comes naturally. It's building a relationship that can actually support it.

That means making explicit agreements about boundaries rather than assuming you're on the same page. It means having ongoing, honest conversations about attraction and connection, not just when there's a crisis. It means addressing disconnection when it's still small, not years down the road. Strong monogamy isn't passive. It's something you build together, continuously.

When Trust Has Already Been Broken

If you're reading this because something has already happened, you're not alone — and it doesn't automatically mean the relationship is over. But it does mean something has to change.

Real repair takes more than an apology. It takes understanding what led to the breach, taking accountability without getting defensive, and rebuilding trust through consistent behavior over time. It means creating a new foundation — one that's more honest and more explicit than what you had before. That work is genuinely hard. It's also genuinely possible.

A More Honest Starting Point

The real takeaway from The Atlantic piece isn't that monogamy is outdated. It's that we tend to treat it as simple when it's not.

If you want a monogamous relationship that lasts, it's worth asking: are we actually talking about the hard parts? Are we building something intentional, or just relying on assumptions?

The gap between belief and behavior doesn't close on its own. It closes through conversation, clarity, and sustained effort — over time, together.

If you're navigating questions about trust, boundaries, or connection, working with a therapist can help you have these conversations more productively. At Pinnacle Counseling, we specialize in helping individuals and couples build relationships that are both honest and sustainable.
