What counts as an emotional affair?
An emotional affair is a closeness with someone outside the relationship that crosses a line the two of you would both recognize, even when nothing physical happens. Secrecy is often the clearest sign: hiding or deleting messages, or playing down how often you talk. Others include telling this person what you no longer tell your partner, and letting the friendship come first. Couples draw the line in different places, so the most useful step is talking about where yours sits, ideally before anything has happened at all.

Closeness is not the problem
Plenty of people have close friendships outside their relationship, including with people they could find attractive, and those friendships are part of a full life. A partner does not have to be your only confidant, and expecting that of one person can put a great deal of weight on them.
What changes things is less how close a friendship is than what it hides or replaces. A friendship starts to look like something else when it takes up room your partner would expect to be theirs, in ways they have not agreed to and would be hurt to discover.
Signs worth noticing
Secrecy tends to come first. Deleting a thread so it will not be seen, keeping a chat on an app your partner does not know about, turning the screen away when they walk in, or describing someone as "just a colleague" when they have become far more than that. If you would edit the story before telling it at home, the editing is itself information.
Then there is what the friendship carries. You find yourself saving your best news, or your worst day, for this person rather than your partner, or confiding in them about problems at home. You rearrange plans to see them, look forward to their messages more than to your evenings together, or feel a pull of anticipation you would recognize from the start of a romance. One of these on its own may mean little. Several together are worth an honest look.
Drawing your lines together
There is no single rule for where a friendship ends and an affair begins. Some couples are relaxed about long late-night conversations with a friend, and others are not. Some are comfortable staying close to an ex, while others would rather keep exes at a distance. Neither approach is the right one, but two people holding different assumptions without knowing it is where hurt often starts.
So talk about it on an ordinary day, when nobody is under suspicion. Treat it as a conversation about what each of you would want to know, not a rulebook: "Would it bother you if I had dinner alone with a friend you hadn't met?" or "How would you feel if an old flame got back in touch with me?" Come back to it when life shifts, such as a new job with long hours or an old friend reappearing.
If the friendship is yours
If you are wondering about a friendship of your own, a few private questions can help. Is there anything about it you are keeping from your partner, and why? What do you get from this person that you are not getting at home, and have you ever said so to your partner? How would you feel if the friendship ended tomorrow?
If the answers are uncomfortable, you have choices that do not require a crisis. You can step back, bring the friendship into the open by introducing them or seeing them in company, and talk to your partner about anything that feels missing between you. The feeling of being understood by someone new can say as much about a gap at home as about the other person. If you are unsure what you want, a therapist can help you look at it honestly.
If you are worried about your partner
Talk rather than snoop. Checking a partner's phone or accounts tends to make things worse, and it cannot show you what you most want to know. Whether a friendship has started to take up room that was yours is a matter of attention and priority, which a message thread can hint at but not explain, and reading it uninvited gives your partner a grievance of their own. Raise what you have actually seen, as an observation and a feeling: "I've noticed you're messaging Sam most evenings, and I've started to feel shut out. Can we talk about it?"
Then listen. Your partner may see the friendship very differently, and their answer, along with whether they are willing to change anything, tells you more than any search of their messages could. It can also help to ask yourself whether this unease feels familiar from other relationships, or is tied to things this partner has actually done. And if the thought of raising it leaves you frightened of how your partner might react, that matters more than the friendship: do not raise it alone, and talk first with someone you trust or a domestic violence advocate about how to stay safe.
