At a glance
An emotional affair is a close relationship kept partly hidden, given the attention and honesty your partner is not given, and defended when anyone asks about it. Nothing physical has to happen for it to do real damage. This article helps you work out where your own line sits and what to say next.
Clinical insights from 22 years in psychotherapy
I’m Mark Colclough, MA, psychotherapist in Copenhagen. Qualified at the Psychosynthesis Education Trust and the University of East London. 22 years of full-time, face-to-face clinical practice.
- The word people reach for first. My clients call it a friendship when they arrive, and after the room has been quiet for a while they reach for a different word themselves.
- What hurts most in the room. It is rarely the content of the messages. It is hearing that somebody else knew something first.
- Past the definition. The couples who get somewhere are the ones who stop arguing about what to call it and start saying what each of them needs in order to feel secure.
Clinical notes: My observations are anonymised and compounded from my session notes since 2004.
What makes it an emotional affair rather than a friendship?
Secrecy, the kind of closeness that used to be your partner and nobody else, and a sharpness that arrives whenever anyone asks about it.
- Secrecy. Your partner does not know the whole of it, and the editing happens before you notice you are doing it.
- Displaced closeness. This person gets the version of you your partner used to get, including the bad day before it is tidied up.
- The sharpness when asked. A question about a friend gets an answer. A question about this one gets a tone.
- The dinner question. Ask whether you would describe this friendship honestly, in full, with your partner at the table. It tells you what you are protecting rather than delivering a ruling, because people keep some friendships private for sound reasons, including a friend who asked them to.
What gives it away is small and ordinary. You tell yourself nothing has happened, which is true, and you are also checking at half past four whether a message has come, and turning the phone face down when your partner comes into the kitchen. Nothing has happened, and the day is already arranged around it.

Why does it hurt so much when nothing physical happened?
Because what was given away was the inside of your life, and that is a betrayal rather than an overreaction.
It arrives as a drop under the ribs, then as embarrassment at feeling so much about messages you have not even read. There was no sex, so you have no single event to point at, and you set about talking yourself out of the feeling. That is the part I would ask you not to do. In a national survey of 2,000 American adults, 76 per cent counted a married person keeping a secret emotional relationship as infidelity, and 72 per cent said the same of one conducted online1. The figures ran higher among the married respondents, and the data are several years old now.
What no survey settles is where the line falls between the 2 of you. It tells you the feeling is not eccentric. It does not tell your partner what they owe you, and that conversation is still ahead. Read more about what jealousy in a relationship is telling you.
How does it start when nobody decided on it?
Through a long run of small moments in which reaching out stopped seeming worth it, rather than through a decision anybody made.
You see it afterwards and not at the time. One of you mentions something small, a worry about a parent or a bad hour at work, and the other is tired, or on the phone, or answers in a way that closes it. It happens again the following week. After enough of them the one doing the reaching stops reaching, and what fills the gap is not a decision to betray anyone. It is relief at being asked a question by somebody who waits for the answer.
- The sequence has a shape. The clinical literature I have read2 sets out the same cascade: a bid for attention, a partner who turns away or turns against, the bidder holding back feelings and needs, and honest disclosure avoided from then on.
- Comparison comes before concealment. The relationship starts being measured against alternatives, real or imagined, and the hiding begins with leaving things out rather than with lying2.
- The ground it grows in. Disconnection, feeling unloved, an imbalance where one partner takes a parent-like role, low self-esteem and fear of commitment are among the reasons people give3.
None of that excuses it and none of it divides the responsibility equally. The person keeping the secret is the one who chose to keep it. What it explains is why promising harder fails: the promise is aimed at the last step of a sequence that began a long way back. Read more about a partner who runs hot and cold.
What do you do if you think your partner is in one?
Say what you have noticed and leave out what you have concluded, because the conclusion is what the argument will then be about.
The phone goes face down. The name changes the temperature of the room. You want to know what this is. Put like that it is a description, and a description is harder to argue with than a charge. You need no proof to ask. Being unsettled in your own home is reason enough to want a straight answer, and nobody requires you to build a case first.
Leave the phone itself alone. Reading messages hands you fragments without their context that you cannot unread, and the next argument becomes about the reading. If the denial comes and nothing about the behaviour changes, you have learned something painful and worth knowing. Say what you want as well as what you fear: less contact, or none, or an end to the editing.
How do you end it and repair the damage, and when is that not enough?
End the secrecy first, tell your partner before they discover it, and change the arrangement rather than the strength of the promise.
- Notice what you are protecting. If you are deleting messages, the deleting tells you more than any definition will.
- Tell them before they find out. A discovery adds the concealment to the thing concealed, and the concealment is the part that takes longest to repair.
- A discovery is a harder start and not a closed door. Couples come through one. It costs more.
- The secrecy is the part that is not up for negotiation. Everything else is open to discussion, including whether the friendship continues at all.
- Make the change visible. No separate account, no messages your partner knows nothing about, and a straight answer when they ask.
- Write down 3 things each. Each of you lists 3 behaviours you would count as crossing the line, separately, before either of you reads the other list.
A promise with no change in the arrangement keeps the thing while looking like it has been given up. Comparing 2 lists is a conversation; ruling on an incident is a court case. Read more about what recovery after an affair asks of each of you.
These steps are not enough while the contact carries on in a smaller form, or while every conversation becomes a trial over whether it counted. They are the wrong steps where one of you is monitored or frightened at home: becoming more open assumes it is safe to be open, and that needs separate support first. What stays uncertain is whether the closeness between you returns, or whether the relationship has been running on habit for longer than either of you has said out loud. That is worth looking at slowly.
Questions people ask
Can we bring this to therapy if we disagree about whether it even counts?
Yes, and that disagreement is the most useful thing in the room, because it shows what each of you treats as private and what each of you treats as shared. I do not need the 2 of you to agree on a label before the work starts.
What if my partner will not come with me?
Come on your own, because a great deal of this work is about what you want, what you will ask for and what you will do if nothing changes. Couples work stays available later if your partner changes their mind.
Will you tell me whether what happened counts as an affair?
I will not rule on it, because a verdict from me would settle an argument that belongs to the 2 of you and would not hold once you were home. What I do is help each of you describe where your own line sits and why it sits there.
Do I have to tell my partner everything in the first session?
No, and I will not force a disclosure in a first session, because a half-managed account given under pressure does more harm than one told properly a week later. I will ask whether you intend to tell them, and when.
How do I choose a therapist while we are in the middle of this?
Ask whether they work with couples around secrecy and infidelity, whether they take a position on what counts as cheating, and how they handle it when only one of you wants to be there. I offer a free 30-minute call so you can ask first.
Whether you strayed or found out, I can help you make sense of it in infidelity therapy on your own before you talk together.
