7 signs your partner might be having an emotional affair

When your partner shuts down, it can be hard to tell if what you're dealing with is just a rough patch in your relationship—or if he's hiding something from you. Maybe he's being faithful physically, but what about emotionally?

Emotional affairs are much less defined than physical ones, which is why they're so challenging to pinpoint, says Jane Greer, Ph.D., author of What About Me? Stop Selfishness From Ruining Your Relationship. With developments as subtle as lingering glances, it's not always easy to see when a friendship has blossomed into something more. If your gut is telling you that something's off, here are seven signs to look out for that might indicate your S.O. is having an emotional affair. If several apply, consider having a discussion to clear the air.

1. Your Sex Life Has Drastically Improved—or Dropped Off

When a person is having an emotional affair that hasn't yet turned physical, the frequency of sex with his or her partner can actually increase. "The passion for the one he desires is played out in the relationship he's already in," says psychotherapist Ginnie Love, Ph.D. Of course, every guy is different—for some, when there's an uptick in emotional intimacy with someone new, the level of sexual interest in his current partner takes a nose dive.

2. He Seems Distant or Detached

If your guy is scoring attention and emotional support from someone else, he might stop discussing the intricacies of his life with you. We only have so much emotional energy to go around, says Love, and our attention tends to go where we are most drawn. Over time, this can also lead to physical detachment. "If your partner is spending the time he previously spent with you on someone else, that is an immediate warning sign that needs to be addressed," adds Love.

3. His Attitude Toward You Has Changed

In addition to pulling away, he may start praising his new obsession and criticizing you—say, throwing shade about your cooking skills or taste in movies, even though these aspects of your personality never seemed to bother him before. "This is especially dangerous territory because he may be unconsciously sizing you up," says Love, comparing you to a fantasy version of the other person and idealizing what it might be like to be with her.

4. His Tech Habits Have Changed

If he doesn't text very often and is suddenly glued to his phone or spends more time browsing on social media than he used to, this is a behavioral change that might signify something's up, says Love. And if he starts dodging details about who he's keeping in touch with, this could be a subtle admission of guilt. "On some level, he knows what he's doing isn't quite right and that you'd understandably feel jealous, so he avoids and evades, thinking that what you don't know won't hurt you," says Gail Saltz, M.D., psychiatrist and author of The Power of Different.

5. He Drops Her Name Constantly

"We mention friends from time to time, but a constant name drop is disrespectful and inappropriate," says Love. It's basically an invitation for you to call him on it. And when you do, take note of his reaction. If he's super-defensive about their friendship, reiterates that there's nothing going on between them multiple times, or is super-forceful about wanting you to believe him, it might be time to take stock of his loyalty, says Saltz.

6. He Argues With You Differently

If you're hearing new and surprising comments from him in response to disagreements you've been having for a long time, it could be a sign that he's been spilling on your relationship issues with her, and then absorbing her commentary on them."Chances are these are her responses when he tells her about fights the two of you have, and he's taking them in and using them in your arguments," says Saltz.

7. Youre Starting to Feel Like the Third Wheel in Your Own Relationship

Say you're at a party with your mate and his friend shows up. If your guy immediately leaves you alone to tend to her needs, that's the big red flag. "If you start to feel like you're not number one and that everything significant isn't being shared with you first, you may not be on solid ground in your relationship," says Greer.
