23 Signs Your Girlfriend Is Cheating On You

Physical Signs

Here are some physical signs that hint your girlfriend is cheating.

  1. She’s in constant touch with another person

You used to be the reason behind your girlfriend’s addiction to her phone. She used to smile while chatting or talking to you. But now, she is enjoying talking to some other person. If you have noticed it for weeks or months, it could be a red flag indicating an affair to watch out for.

  1. She has a password to her phone

Has she locked her phone suddenly? If she has been an open person all the while and now locked all her devices, it could be suspicious. In case she doesn’t have a valid reason, it adds more to the distrust.

  1. She dresses differently

Your girlfriend starts to care about her appearance after years of wearing a baggy t-shirt and jeans, tying a messy bun, and not putting much effort into her looks. She started experimenting with her looks and is trying new outfits, which could raise a suspicion that she could be trying to impress someone other than you.

  1. She doesn’t want your company

She starts to spend more time with her friends, ignoring that you are alone. Also, she is not inviting you to any of her parties and insisting you stay at home and play the game. It shows something is wrong with her intentions and you need to be more observant to notice the signs before she betrays you.

Is she losing interest in getting intimate with you, or her desire for getting closer has changed? You may check for changes such as how often she is kissing or hugging you. It can help you be sure of her thoughts and check for signs of infidelity.

  1. She avoids public display of affection

Your girlfriend used to be happy with you, be it at a restaurant or in the mall. But now, she feels uncomfortable when you hold her hand or hug her in public. It shows she is getting away from you. Her lack of interest in you could be a reason for you to doubt her intentions.

  1. She shows through her body language

Closed body language can be a sign of guilt and lie over cheating on their partner. You may look for cues such as avoiding eye contact, folding arms over chest and turning away.

  1. She doesn’t care for you

In a relationship, partners care for each other. But if your girlfriend stops caring for you, overlooks your caring gestures or is not paying attention to you, it shows something is wrong between you both.

  1. She provides hints of breakup

Is she blaming you for everything? Is she picking up fights for no reason? When your girlfriend indirectly shows that she is not happy in the relationship, it could be a sign that she is not interested in you anymore. Perhaps the unnecessary fights are a ploy to break up with you.

  1. She isn’t ready for the wedding

At the beginning of the relationship, you both have agreed on spending life together. However, she changes her plans and postpones the wedding without any strong reason, which means she is an unreliable partner. She might even try to deceive you and tell you she doesn’t want to marry, giving no valid reason.

  1. She doesn’t share your plans

When you are in a relationship, you accept that you and your partner are well aware of each other’s plans. But your girlfriend doesn’t let you know about her whereabouts, keeps secrets from you or hides her plans from you. It could hint at something more serious.

  1. She doesn’t crave your attention

She complained that you were not paying attention to her, but now she is not bothered even if you don’t call her or ask about her wellbeing. It seems she doesn’t want you to think about her.

  1. She turns off notifications

Your girlfriend’s phone is not buzzing with messages and notifications as she has kept her mobile on silent mode. When you ask her why she doesn’t give you convincing answers. This can make you raise your eyebrow.

  1. She doesn’t make an eye contact

One of the visible signs your girlfriend is cheating on you is when she is not making eye contact with you. Try to cross-examine her. If she is cheating on you, she would be guilty of her actions. And so, you might find her escaping from your sight.

  1. She keeps changing her schedule

Is your girlfriend working late often or has little time to spend with you? Have you ever caught her sneaking out of the house? Does she postpone your scheduled dates and show she is busy all the time? If yes, all these signs show that she is avoiding you and could be busy with some other interest.

  1. She doesn’t want to share with you

In a relationship, partners are emotionally attached and share their dreams, plans, and other stuff. But for a few days or weeks, your girlfriend is not happy to share anything with you. She is isolating you at times too. It shows something else is on her mind, and not you.

  1. She is flirty with others

Whether you are teasing her or loving her, she easily gets irritated. She might even make a scene and blame you for her bad mood. There could be another interest in her life, hence she is going away from you.

  1. She picks fights with you

Fights can be common in a relationship, but if it has reached an alarming level and sometimes for no reason, it could be a sign of disturbance. Your girlfriend could be playing a tactic on you to escape from the situation. Overall, she may not pay heed to your emotional needs.

22. She criticizes you constantly

You may notice a sudden change in her behavior. The person who wholeheartedly appreciates everything you did for her now criticizes you for everything. Even your small flaws are being pointed out and criticized. She seems constantly dissatisfied with your efforts to please her and finds faults with everything you do. This can be because she has lost interest in you and is always comparing you with her secret lover.

23. She has less patience

She seems to have almost zero tolerance and blasts at you for the silliest reasons. She is acting dismissive and always seems to be frustrated with you. She may also give you frequent ultimatums and threats about ending the relationship if you do not act according to her will.

What To Do If You Think Your Girlfriend Is Cheating?

If you are sure she is cheating on you, confront her

If you could relate to most of the signs, you should know your girlfriend may be having a clandestine relationship. However, if you still are doubtful, you might wait for some more time and keep noticing. But if you are confirmed, then it is better to confront her. If she confesses that she doesn’t love you anymore and wants to break up with you, let it go. Do not force her into a relationship.

Aaron Marino, a vlogger on YouTube, shares his experience of breaking up with his girlfriend, who cheated on him for five years. He says, “I allowed it to happen because I was unable to take care of myself. I let this go on for five years until I finally understood that this was insane and deserved to be with someone who loved me and appreciated me. It was incredibly hard to break up, but I knew that if I ever wanted to be happy, I needed to end this relationship (i).”

On the other hand, if she feels guilty about it, admits she took a wrong step and seeks the last chance from you, think about it. Instead of breaking up immediately, you may take your time and make a decision. Ultimately, it is your choice, so listen to your intuitions.

Frequently Asked Questions

1. How to know if your girlfriend is cheating on you in a long-distance relationship?

Signs that your girlfriend is cheating on you in a long-distance relationship include her reluctance to have you visit her, getting confused when recounting memories or telling in a disorderly fashion. She may also talk about hanging out “with friends” but don’t give specific names.

2. How do you tell if your girlfriend is lying about cheating on you?

If you confront your girlfriend about cheating on you and she denies it, look for certain signs to see if she is lying. When you are questioning her, you may notice that she’s nervous, her voice cracks or becomes high-pitched, she avoids eye contact, becomes fidgety, and exhibits bodily expressions such as crossing her arms, pursing her lips, and sweating (in some people).

3. How can I tell if my girlfriend suddenly becomes overly defensive or evasive when I ask about her day?

Ask her what she did during the day; if your girlfriend has nothing to hide, she will gladly share the activities she engaged in. But if she changes the topic instead of answering you or gets irritated and wants to know why you are asking her the question, it may mean she is avoiding your question to hide something. However, you cannot conclude she is cheating on you just because she’s not sharing what she was up to, as there could be various reasons for her behavior.

Look out for these red flags if you wish to know if your girlfriend is cheating on you. Doubtfulness can ruin a perfectly good relationship. So as hurtful as it may seem, it is better to stay aware and address the issue than to be oblivious to cheating. So, if you notice these changes that seem suspicious, unlike her usual self, do not hesitate to confront her. Calmly ask her about what must be causing these behaviors and take a call if you can undo the damage or it is better to let go. However, be gentle, don’t make assumptions, and work on your relationship.
