Signs of an Emotional Affair, According to Expert Therapists

Physical affairs are blatant betrayals, but emotional affairs tend to be more subtle in the boundaries they cross. An emotional affair might unfold slowly through a series of small shifts that seem harmless at first but grow into something more intimate. Maybe your partner smiles at their phone before they even realize you noticed. Or perhaps you’ve caught yourself wanting to text one particular person whenever something thrilling, funny or frustrating happens—before it occurs to you to share it with your partner.

Of course, having a close friend outside your relationship is common, and it’s not an automatic red flag. So where’s the line, and what actually defines an emotional affair?

Relationship experts share how to distinguish when an innocent acquaintanceship has shifted into an emotional affair.

“A relationship crosses a line into infidelity when any kind of outside relationship becomes something you hide from your partner,” Tammy Nelson, PhD, a board-certified sexologist, sex and couples therapist, and author of seven books including The New Monogamy: Redefining Your Relationship After Infidelity, tells MyLifetime. 

If your partner knew the full extent of the relationship, it would likely feel like a betrayal, suggests Tracy Ross, LCSW, a couples therapist in New York City. Ross tells MyLifetime an emotional affair involves intimacy and closeness with someone other than your partner when you’re in a monogamous relationship. 

“It’s not defined by whether it becomes physical—it’s defined by where your emotional intimacy is being invested,” Ross explains. An emotional affair often occupies a gray area since, unlike a physical affair, there’s not a clear encounter that defines it. Instead, the intention slowly shifts outside the center of the individual’s committed relationship.

This is where things get tricky. Plenty of people confide in close friends outside their relationship. However, things become less appropriate when that friend starts taking up the emotional space your partner used to occupy. The other person increasingly becomes your “go-to” instead of your partner, and some level of secrecy enters the mix.

Emotional affairs rarely begin with the intention of stepping out of your relationship—That’s part of what makes them so easy to miss while they're happening. More often, they start as friendships that feel like a breath of fresh air during a stressful season, or a connection that fills a void you didn’t realize had been lingering.

Both Ross and Dr. Nelson say that depends. Some people would rather discover a physical indiscretion than learn their partner shares their hopes and fears with someone else. Others feel the exact opposite. That’s why it’s difficult to say one kind of infidelity is preferable.

According to Dr. Nelson, emotional affairs are still a type of betrayal (even more so if the affair partner is a close friend, colleague or someone you both know). “If there has been sexual flirting, photos shared, potential hookup conversations or comparisons to your sex life at home, this can be devastating [to your actual partner],” she adds.

No matter the type of infidelity at hand, the experts have observed that it’s the dishonesty that’s most catastrophic to the relationship. “While some might be bothered by the feelings between you, even if there has not been sexual interaction, the secrecy violates the implicit relationship agreement,” Dr. Nelson says.

Dr. Nelson invites you to think back to your elementary school days, if friends would ask if you “like-liked” someone. “They were trying to differentiate between friendship feelings and something more,” she says. “An emotional affair can feel like that—like a crush.” 

You might find yourself investing a lot of energy into them, even when you’re not actively communicating. “Your thoughts, feelings and fantasies may start to revolve more often around the person, and you may be focused on when you will talk with them next,” Dr. Nelson continues. 

You might replay conversations in your head, or catch yourself checking to see if they’ve replied. Maybe you spend a little longer getting ready when you know you’ll see them. Essentially, these moments could mimic the early stages of dating when everything’s new and exciting.

According to Ross, a harmless friendship evolves into an emotional affair when the other person becomes a stand-in for your significant other. 

Think about who gets the first text when something happens—good news at work, a fight with your sister or simply one of those days when you need someone to lean on. If they become your default source of celebration, comfort or reassurance, it shows that you're drifting outside of the relationship.

Do you flip your phone over when your partner walks into the room? Minimize or downplay how often you speak to this other person? Secrecy is one of the most obvious signs that a friendship has crossed into an emotional affair. “When you find you are hiding conversations, deleting texts or telling yourself, ‘My partner just wouldn't understand,’ you’ve probably already crossed the line,” Dr. Nelson says. 

The secrecy could even be thrilling—creating an emotional charge that feels romantic or sexual—but it could also bring with it a sense of shame or guilt, Ross adds. The two feelings may even coexist.

If you’re wondering if your partner is having an emotional affair, Ross calls out a few red flags to look out for: “You may have a growing sense that they have become unusually close to a particular person, notice that they hide or minimize their communication or become defensive when you ask about the relationship.” 

This person could come up in conversation all too often—or strangely, not at all. To deflect, your partner may say that you’re overreacting when you’ve simply responded to a palpable shift. In some relationships, they may repeatedly dismiss your concerns or insist you’re imagining things, leaving you questioning your own instincts.

If you’ve determined that you’re having an emotional affair yourself, Dr. Nelson suggests looking inward. One of the biggest misconceptions about emotional affairs is that they’re always about finding a better partner—but that’s not often the case. 

“After almost 35 years of being a couples therapist, what I see is that most people don’t look for another person—they look to be another person,” she explains. “Emotional affairs happen because the partner discovers a part of themselves they have been missing when they are with this new person.” 

Perhaps they make you feel funny or sexy again—like a version of yourself you haven’t seen in years. Or maybe they bring out your wit or intellect, whereas conversations with your partner don’t invite the same kind of novelty, whimsy or reassurance you crave.

Eventually, the two therapists say, the time to come clean may arrive. If it does, own what happened without minimizing it. Be honest about how the relationship evolved, say what you’re willing to do to rebuild trust and make room for your partner’s hurt. Listen to—and validate—their experience. According to Ross, the important question isn’t who’s right or wrong, but whether trust, emotional safety or the agreements of the relationship have been compromised.

If you suspect that your partner is having an emotional affair, you’ll want to ease into the discussion just as carefully. It’s natural to want answers immediately, especially if you’ve been losing sleep over it. Ross advises leading with curiosity rather than launching into accusations. Aim to speak from your own experience with statements starting with phrases like I feel, I notice or I’m struggling to understand. 

“When people feel accused, they usually become defensive,” she says. “On the other hand, when they hear the impact their behavior is having on their partner, they're much more likely to stay engaged and willing to take in what their partner is sharing.”

If your partner confesses that they are, in fact, having an emotional affair, Dr. Nelson says you shouldn’t resort to blaming yourself. “It is unfair to think that you are inadequate in some way, or that you are not enough for your partner,” she says. “It may be that they are looking for something in their own life that they are trying to find in themselves.” 

Again, she reiterates that emotional affairs are more about the person starting them than anything (or anyone) else. “Most emotional affairs start because people are looking to feel more alive, more understood or more desired.” It’s at this junction where you’ll have to ask if these needs can be met with your current partner, and vice versa.

Whether the relationship ultimately survives isn’t a question anyone else can answer. But both therapists agree that emotional affairs don’t get resolved through avoidance. They require honesty about what happened, curiosity about why it happened and the courage to determine what comes next.
