What Counts as Cheating?

Is liking her photos cheating? What about DMs that "mean nothing"? The definition of cheating keeps shifting. Here's what God's standard for covenant loyalty actually says about all of it.

Instagram DMs, emotional affairs, and the blurred lines destroying covenant

Marcus thought he knew exactly where the line was.

No sex with anyone else. That was the rule. That was the definition. Everything else was just... life. Talking to people. Being friendly. Having a personality.

So the Instagram DMs didn't bother him. They were harmless. He wasn't doing anything wrong. He was just talking. She made him laugh, that's all. He never lied to Nicole about it exactly. He just didn't bring it up.

Nicole found out the way most spouses find out. Not because he told her. Because something felt wrong, and then the proof showed up to confirm what she already knew in her gut.

She was devastated. He was defensive. And the argument that followed might sound familiar:

"I never cheated on you."

"You were talking to her every single day."

"We were just talking. Nothing happened."

"Something happened to me."

They were both telling the truth. And that's exactly the problem.

The Question Nobody Agrees On

We hear some version of this in our office more than almost any other question: "Is what my spouse did actually cheating?"

And honestly, the answer has gotten harder to give. Not because the standard has changed. But because the world couples live in has changed dramatically, and most marriages have never had a clear conversation about where their lines actually are.

A generation ago, cheating meant one thing. Physical. A hotel room. An affair with a body attached to it.

Today it's a text that says "thinking about you." A late-night voice note to someone your spouse doesn't know exists. Sliding into someone's DMs and sliding back out before your spouse ever sees the notification. Liking every photo she posts while being emotionally unavailable at home.

The behaviors have multiplied. The definitions haven't kept up. And that gap is destroying marriages.

Why the Definition Keeps Shifting

Part of what makes this so complicated is that the culture has spent years telling us that connection is connection. That intimacy can be casual. That following someone, messaging someone, admiring someone online is just... normal. Everybody does it.

And because everybody does it, people start to believe that nothing they're doing is wrong. They've never technically crossed the line because they've decided in their own mind where the line is. And they've placed it conveniently just past whatever they're currently doing.

That's not a covenant standard. That's a personal comfort standard. And those two things are not the same.

Here's something worth sitting with: when you get to decide where your own line is, you will always draw it just far enough to protect your behavior. Nobody draws the line on the other side of something they want to keep doing.

That's exactly why marriages need a shared definition. A covenant-based one. Not one that shifts every time a new app makes a new behavior feel normal.

The Spectrum: From "Harmless" to Clearly Over the Line

Let's actually walk through the behaviors that couples argue about, because naming them specifically is more helpful than staying vague. You've probably had at least one fight about something on this list.

Following and liking

On its own, liking someone's photos is a small thing. But when it's consistent, intentional, and directed at one particular person your spouse doesn't know about, it's a signal. It's not automatically cheating, but it's a habit worth examining. Ask yourself: would my spouse be comfortable if they saw exactly what I'm doing and how often I'm doing it? If the answer is no, that's worth paying attention to.

DMs and private messaging

This is where things move faster than most people expect. A conversation that starts public becomes private. A private conversation becomes personal. A personal conversation becomes the highlight of your day. And then one morning you realize you know more about this person's life than your spouse knows about yours.

Private messaging with someone your spouse doesn't know about is not a small thing. Secrecy is the ingredient that turns a conversation into a problem.

Emotional affairs

This one is real, it's painful, and it is cheating. When you are sharing your inner life with someone outside your marriage... your struggles, your dreams, your frustrations with your spouse... that's intimacy. God designed that kind of intimacy to belong inside the marriage covenant. When it goes outside, covenant is being violated.

We covered this in depth in our post on He Never Touched Her. It Still Almost Destroyed Our Marriage, but the short version is this: the absence of physical contact does not make an emotional affair harmless. It makes it different. Not lesser.

Micro-cheating

This is the term people use for smaller behaviors: saving someone's contact under a fake name, deleting message threads before your spouse sees them, telling someone outside your marriage that your spouse "doesn't understand you," maintaining a close friendship that you deliberately keep separate from your marriage.

None of these things may be "cheating" by the old definition. But they are all forms of secrecy. And they are all building walls between you and your spouse while building connections somewhere else.

Physical affairs

Still cheating. Always has been. The definition didn't change here. What changed is that now it's often the last step in a progression that started months earlier in someone's DMs.

What God's Standard Actually Is

Here's the thing about using "everyone does it" as your standard: it will always let you down. Cultural norms are not covenant norms.

The biblical standard for marriage is not "don't sleep with someone else." That's the floor, not the ceiling.

Proverbs 4:23 says to guard your heart above all else, because everything you do flows from it. God's instruction is not about behavior management. It's about protecting the source.

When Jesus addressed adultery in Matthew 5:28, he went straight to the heart. The internal investment. The mental and emotional energy. His standard was not about what your hands did. It was about where your heart was pointed.

Genesis 2:24 describes the "one flesh" union of marriage as a complete merging. Not just bodies. Lives. Emotional worlds. The intimacy that belongs to the marriage relationship is not limited to the bedroom. It covers the whole person.

And Malachi 2:14 makes clear that God takes covenant seriously. He was a witness to your vows. Which means He sees not just the actions, but the drift. The slow transfer of emotional investment away from your spouse and toward someone else.

Here is a simple standard we use with couples: if you would do it differently if your spouse were watching, you have your answer.

That's not a complicated formula. It's just honesty.

The Conversation Every Couple Needs to Have

Most couples have never sat down and talked through what their actual boundaries are. Not in a legalistic way. In an honest, protective way.

What does faithfulness look like in our marriage specifically? What behaviors are we comfortable with and which ones feel threatening to our covenant? What does transparency look like for us when it comes to phones, friendships, and social media?

These conversations feel awkward because they require vulnerability. You have to admit that some things feel threatening to you even if you can't always explain why. You have to listen to your spouse's concerns without getting defensive.

But couples who have had this conversation are far more protected than couples who assume they're on the same page.

The Agreement of Boundaries we walk couples through includes this: no secret conversations, no hidden relationships, transparency about phones, passwords, and social media. Not because we believe in surveillance. Because we believe in covenant. And covenant requires that there are no rooms in your life that your spouse isn't allowed into.

That's not control. That's trust. And trust requires having nothing to hide.

How to Set Boundaries That Protect Your Marriage

If you and your spouse have never talked explicitly about digital boundaries, here are some places to start:

First, agree that secrecy is the problem, not the platform. It doesn't matter whether the issue is Instagram, Snapchat, a gaming platform, or a group chat. Secrecy is what makes any of these things dangerous. Openness is what keeps them safe.

Second, get specific about what feels threatening. Don't just say "I don't want you talking to her." Talk about why. What does that behavior represent to you? What fear is underneath it? This is a harder conversation, but it's a more useful one.

Third, set agreements you both actually believe in. Not rules one person is imposing on the other. Mutual agreements between two people who both want to protect their marriage. When both people are invested in the boundary, it holds.

Fourth, check in regularly. The digital landscape changes. New apps, new platforms, new normals. What felt like enough protection two years ago might need to be revisited. Calibration is ongoing, not one-time.

And if you're in a place where lines have already been crossed and you're not sure how to start the conversation about it, that's exactly the kind of situation where getting outside help makes a real difference. You don't have to figure out how to have that conversation alone.

A Word to the Spouse Who Is Questioning Their Own Behavior

If you've been reading this and something has been sitting heavy in your chest, pay attention to that.

God designed your conscience to be a guide. When something feels off, it's usually because something is off.

The question is never really "is what I'm doing technically cheating?" The better question is: "Is what I'm doing protecting my marriage, or am I making withdrawals from it while telling myself the account is fine?"

Covenant doesn't ask for technicality. It asks for loyalty. Full, unhidden, heart-level loyalty.

That's a higher standard than most people live by. But it's also the kind of standard that actually protects something worth protecting.
