What are the Physical Signs Your Girlfriend is Cheating on You?

An intuitive feeling that your partner is being unfaithful might be related to a series of little signs you’re subconsciously picking up on. These signs may be related to body language or subtle to significant changes in behavior. But sometimes, we fail to notice them or we make excuses for our partner. Sometimes we even jump straight to trying to win her love in the hope that they'll stop cheating. But that’s because denial is a heck of a strong drug even when the truth is staring you in the face.

Here are the signs most guys overlook. They could indicate your girlfriend is cheating on you.

One telling physical sign your girlfriend is cheating: she has a newfound spring in her step

If your girlfriend recently got a promotion at work, celebrated a special achievement or got some great news; it makes sense if she seems happier than usual. But does your partner seem happier for no apparent reason? Does she seem oddly jolly and you can’t figure out why?

This could be a subconscious display of a boost in confidence. And it could be because someone makes her feel desired.

She spends most of her time at the office

We tend to like or love the people we spend the most time with. So if your girlfriend spends a lot of time at work with her colleagues, she may be interested in more than her career.

Does she often talk about a particular guy at work? Is she vague on the details of why she’s working long hours all the time? Does she seem to prefer being at work than spending time with you?

If the answer is yes, it’s possible she’s cheating.

You get the feeling she isn’t truly happy

If a woman isn’t happy in her relationship but doesn’t have the courage to tell you, she’s likely to cheat.

Take some time to think about how your girlfriend has been acting around you recently. Is there any good reason to suspect she isn’t happy with your relationship? Is she never in a good mood? Do you sense a negative vibe when she’s around these days?

If something is telling you she’s not happy, it’s worth taking the time to ask her what’s going on. It might be totally innocent like stress at work or family worries. But you won’t know until you ask.

You don’t spend quality time together

Has it been an age since you last went on a proper date? Maybe you haven’t had quality alone time with each other? Does your girlfriend prefer to spend her free time with her girlfriends or doing things solo? Does she leave you on your own a lot of the time, feeling a bit like a third wheel in your own relationship?

If she doesn’t want to do any of the usual couple stuff (including intimate activities), someone else could be filling in for you.

She avoids eye contact with you

If she avoids eye contact at all costs, it could be one of the physical signs your girlfriend is cheating. People only tend to do this when they have something to hide. They also do this when they aren’t telling the whole truth.

If you notice she can’t look you in the eye, it could be suspicious. She might be trying to avoid contact because she doesn’t want to give herself away.

However, you don’t want to confront her without proper reason. If this continues, find an appropriate time to bring it up when both of you are in a calm state.

She’s getting more attractive each day

You notice that your girlfriend has been making a lot of effort with her physical appearance lately. But you’ve got a feeling it’s not for you!

Has your partner started hitting the gym, after years of being a couch potato with you?

Has she started dressing up more? Is she wearing more makeup even when you’re not going out together? Is she putting more effort into her outfits when she used to prefer jeans and a t-shirt? Has she recently gotten a dramatic new haircut after sporting the same old bob for yonks?

Worst of all, is she doing all these things almost exclusively when you won’t be together that day?

These could merely be signs that she’s beginning to feel more confident in herself and wants to express that. But they could also mean she’s trying to impress somebody else.

Physical signs your girlfriend is cheating: she has a new favorite sex position

If your girlfriend is acting differently in bed--telling you about a new favorite position, introducing sex toys, or suggesting a threesome--it may be because she’s opened up to a new level of sexuality.

This could be no more than her wanting to experiment and spice things up in your relationship. But it could also be she’s learned new moves from some other guy she’s getting busy with.

Or, she avoids being intimate with you altogether

The other extreme is she avoids any kind of intimacy with you, period. She no longer wants to hold your hand in the street, hug you, kiss you or do anything with you in bed. If your relationship used to be quite physical, but now she makes any excuse not to touch you, it’s a sign she’s pulling away from you both physically and emotionally.

Sex expert Robert Weiss explains, “Both decreased and increased levels of sexual activity in your relationship can be a sign of infidelity. Less sex occurs because your partner is focused on someone else. More sex occurs because they are trying to cover that up.”

She avoids serious conversations with you

Have you often tried to have serious chats with your girlfriend, but she gets uncomfortable? Maybe you even try to genuinely talk to her to see what's going on. Does she often brush off or laugh off any talk about commitment and the future?

This might just be a fear of commitment. But it could indicate something more serious like her knowing she doesn’t want a future with you. If you often hear her saying “I” instead of “we” when speaking about the future, that’s another sign she doesn’t see you in hers.

One of the top physical signs your girlfriend is cheating: she’s on her phone more than usual

Cheaters tend to spend more time on their phone or computer. They will start to guard their phone or online accounts fiercely because, of course, they have something to hide.

If she never used to spend much time on her phone but now she’s glued to it, it might mean something’s going on. Then if you ask her about it, and she gets super defensive about it. Other clues like deleting messages and clearing her browser history both indicate infidelity.

She’s suddenly jealous and suspicious of you

When someone is cheating on their partner, it can often make them paranoid about what their partner might be up to. So if your girlfriend has recently become jealous about you receiving attention from other women--friends, co-workers, or even randoms in the street--it might be because she has a guilty conscience.

Many cheaters project their actions onto their partner. So one physical sign your girlfriend is cheating is when she accuses you of cheating. That’s because in her mind if she catches you cheating first, it removes the blame from her.

She has already lied to you

If you’ve already caught your girlfriend out telling lies about where she’s been or who she was with, it can be hard to trust her again.

This is a big sign that your girlfriend might be cheating on you, but she can't bring herself to break up with you. Once people start lying, they can get caught up in their own web and feel like there’s no way out.

What to Do If You See Physical Signs Your Girlfriend Is Cheating

Even if you have a strong suspicion your girlfriend is cheating, you need to be careful about finding proof. You don’t want to invade her privacy or become a stalker boyfriend.

Here’s is a list of things you should NEVER do:

  • Check her phone or emails,
  • Listen in on her phone calls,
  • Search through her browser history,
  • Interrogate her

You might believe you have evidence she’s cheating. But if this is the woman you love, you need to treat her with respect. Remember: she’s innocent until proven guilty. You don’t want to ruin your relationship by invading her privacy only to find out that she’s innocent all along. Then you'll have to do what it takes to win her back.

All the signs above are physical signs she may be cheating. But they’re not for certain.

The best way to find out what’s going on is to simply ask her. Talk to her about your suspicions. Open up about how her recent behavior is alarming. Then look her in the eye and ask her directly if there’s something or someone keeping her from being happy with you.


The fact that you’re reading this article alone suggests that there are issues in your relationship, whether someone’s cheating or not. So you both need to make a decision whether you want to win your wife back, or call it a day and go your separate ways.

In the case of the latter, you'll need to learn how to get over a cheating ex. This guide will help you overcome the struggles that singles usually feel after being cheated on.
