Micro-cheating: where the line sits and how to agree it

What counts as micro-cheating?

Micro-cheating covers small acts that stop short of an affair and that one of you is keeping out of sight. The word came out of the press and nobody has defined it since, so there is no agreed list and no threshold.

• A running flirtation. The tone with one person is different from the tone with everybody else, and it is kept going.
• A hidden friendship. Your partner does not know the person exists, or knows the name and nothing more.
• A reply to an ex. The message is written in a way you would not want read aloud.
• A dating app still installed. The account is unused, kept, and unmentioned.
• A ring taken off. You present yourself as more available than you are.

Each item is ordinary when it happens in the open. What turns it into a breach is that it is managed: deleted, renamed or left out of the account of your day.

Is micro-cheating real, or just a word?

The hurt is real and the term is weak. People do feel betrayed by things that fall short of an affair, and the absence of a research category does not make that feeling unreasonable.

• A media term. It is a new word with very little scholarship behind it, discussed mostly in newspapers and magazines.
• Informal polls. The writing that exists rests on small polls, such as one of 59 people aged 18 to 29, in which about 2 thirds treated following an explicit content creator as micro-cheating.
• A snapshot only. That poll describes one small group of young adults and says nothing about couples in general.
• Easy to stretch. Used loosely, the word turns every ordinary friendship into a suspect, and I have no interest in helping anyone build that case.

Read the term as a description of a situation: something is going on, it is below the level of an affair, and nobody is talking about it.

Why does something so small hurt so much?

It hurts because you have discovered a version of your partner that you were not shown. An affair breaks an agreement you both knew about. This breaks something quieter: your assumption that you hold a rough picture of each other’s lives.

• The picture changes. An exchange has been running alongside yours, and you were not told.
• Two measurements. The scale of the behaviour and the size of the injury are 2 different things.
• “You are overreacting.” That sentence answers the scale and ignores the injury, so the hurt grows.
• Facts against meaning. You both agree on what happened, and you argue for months about whether it matters.
• The unsaid expectation. Neither of you says what you expect of the other, so the argument has nothing to settle on.

Should I check my partner’s phone?

No, because whatever you find, you still have to hold the conversation you were avoiding. Reading messages, tracking locations and going through accounts is common enough to have its own research literature, called interpersonal electronic surveillance.

• What the survey found. In a survey of 259 internet users in established relationships, relationship variables and internet use together predicted how much monitoring people did.
• What it cannot say. It is one survey taken at one moment, so it shows the 2 travelling together and shows nothing about which comes first.
• My own view. Monitoring is far more often a symptom of the state of a relationship than a cure for it.
• No security from reading. I have never seen anybody read their way to feeling secure.
• Looking grows. One search leads to the next, and the search becomes the problem.

An agreement that holds only while one of you is able to check is no agreement. Read more about jealousy in a relationship.

How do you agree where the line is and stop micro-cheating?

You agree the line out loud, and you test each exchange for openness in place of a list of forbidden behaviours. Privacy is keeping something to yourself. Secrecy is keeping something from one particular person who would mind. You are entitled to privacy, and nobody is owed your passwords or your messages.

• Test yourself first. Take the last 3 messages you would not want your partner to see, and ask whether you would hide the words or the fact that the exchange exists.
• Known while it happens. Ask whether you would be comfortable with your partner knowing about this exchange while it is going on.
• Known by name. Ask whether your partner knows this person exists, by name, and how you know them.
• Nothing managed. Ask whether anything is being deleted, hidden or renamed.
• Same beside you. Ask whether you would behave the same way with your partner sitting next to you.
• Ask about the secret. “What was being kept private, and from whom?” opens the subject, where “does it count as cheating?” closes it.

None of these questions asks anyone to give up a friendship. Each asks whether the friendship is conducted in the open, and then each of you says plainly what you expect of the other.

These steps fail when one of you keeps arguing the definition and the other keeps searching for evidence. That is what the session is for.

Questions people ask

Is texting someone else micro-cheating?

No, texting by itself is ordinary. It becomes a breach when your partner does not know the person exists or when messages are being hidden.

Is watching pornography micro-cheating?

There is no settled answer, and couples disagree about this more than almost anything else here. What matters is that you have agreed a position and have stopped assuming the other shares yours.

My partner says I am overreacting. Am I?

The size of the behaviour and the size of the hurt are different measurements. You are able to be right that something was hidden and still be arguing about the wrong thing.

Should I go through my partner’s phone?

No, it very rarely helps. Looking tends to grow, and the conversation still has to happen afterwards.

What is the difference between privacy and secrecy?

Privacy is keeping something to yourself, and secrecy is keeping something from one particular person who would mind. You are entitled to privacy.
