When You Shouldn't Worry If Your Girlfriend is Texting Someone Else
As you may now, infidelity and cheating are incredibly common in today’s society. According to research by National Opinion Research Center, about 12.9% of women (as well as 15.9% of men) in the US aged from 18 to 24 have been unfaithful to their partner at least once.
Sadly, there are no accurate statistics for flirting. There's no reason to debate that fooling around with colleagues or friends often results in romance. That's why you'd definitely want to know how to tell if your girlfriend is texting or making suggestions to another guy online.

However, let’s not get ahead of ourselves. We will talk about sings that could tell that your girlfriend texts another guy in a minute. Before that, let’s go through signs that can tell if you're just a little bit paranoid.
- You are judging others based on your own behavior. Sometimes, men who cheated themselves think that everyone else is prone to doing the same. Do you twitch every time your girlfriend reaches for her phone? Then, maybe the problem is your self-confidence (or lack of thereof).
- Girlfriend lets you handle the phone or doesn’t have a password. Behavior like this should tell you she has nothing to hide. At least not on her mobile device.
- Her expression doesn’t change during texting. Girls tend to behave differently when they receive messages from potential lovers. If your girlfriend doesn't have any emotional reaction, then she probably texts someone insignificant.
How to Tell If Your Girlfriend is Flirting With Other Guys Online?
So, you’re sure you aren’t paranoid, and you have real concerns that your girl talks to other men behind your back? Below you'll find some major clues that your girlfriend is not as faithful as she wishes you would think.
- A lot of her messages are deleted. Over-cautiousness is a valid sign of infidelity. Notice how many dialogue windows are there in the messenger apps she's using. Dialogues at the top of the list are the ones you should explore. Notice any men among there? If the dialogue window is empty or contains a lot of deleted messages – it’s is undoubtedly a worrying sign.
- She locks her smartphone and has passwords for messenger apps. That in and of itself tells she has something to hide. Even more so if the hides the content of messenger apps behind additional PIN-codes.
- An exceedingly high number of notifications. Another viable sign that your girlfriend is texting other guys behind your back. Additionally, you should pay your attention to strange contact names. Especially for contacts that are written in emojis.
- Emotional shifts during texting. As we mentioned before, your significant other's emotions can show that the person she talks with is someone she cares for.
- Her (and your) past. People who cheated before are very likely to repeat it. The same study shows that people who were cheated tend to experience betrayal again. Therefore, if you're suspecting someone who already done it, it's time to move to some serious measures, like installing spy software on her phone.
- Lies about texting. That is it. The big one. If your girlfriend lied about texting another guy – it’s the clearest indicator that something's wrong in your relationship and that she can't be trusted.

Use Web or Desktop Versions of Messenger Apps
The majority of messengers have browser-based versions or desktop apps. If you can secretly activate them using your girlfriend’s phone, then you'll get an excellent opportunity to catch your girlfriend texting other guys. You'll also be able to read all of her incoming and outgoing messages in their entirety.
How can you activate these features? Let’s take a WhatsApp Web service and desktop app as examples.
- Download and install WhatsApp desktop client for your Windows PC or a Mac.
- Alternatively, you can go to WhatsApp Web client on any device, including Linux OS.
- After entering either a web client or a desktop app, you’ll see the following message with a QR code.

- On your girlfriend’s smartphone, go to WhatsApp and click on the upper right corner of the screen.
- Tap “Menu” or “Settings” and select “WhatsApp Web.” Based on the phone's model and operation system, you may need to tap “Menu” and select “WhatsApp Web” there.
- Tap the “plus” icon on the application's upper right corner and select “Scan QR code.”
- Point the camera girlfriend’s phone on the QR code on your desktop’s screen.
Now you're all set! When both of you are on the same Wi-Fi network, you'll get to know what your girlfriend texts to other guys in “real-time,” so to speak.
We should note that the process of linking a phone to the desktop app (or web client) is quite similar in other messaging apps. You could easily do the same with Telegram, Instagram, Viber, or Facebook Messenger if you follow the instructions described above.
Get Tricky with Messaging
A tricky solution that's both risky and effective against potential cheaters. To do this, you’ll have to pretend to be someone else.
Sounds interesting? Then follow these steps:
- Take hold of your girlfriend's phone and visit all of her messaging apps.
- Look at the dialogue boxes at the top of the chat section. These are usually the people she texts the most.
- Pay special attention to the empty dialogue boxes or those that have a lot of deleted messages.
- Identify the names of these contacts in her phone's address book.
- Now, you have two options:
- Text suspicious guys from your girlfriend’s phone while pretending to be her.
- Edit the contact info of her potential lovers on the smartphone's contact list. Replace his telephone number with yours. Text your girlfriend later, pretending to be that man.
We should warn you: this method is risky for your relationship. If it turns out that you're wrong about your girlfriend texting another guy, you could ruin any trust left between you.
But what if you want a more fail-proof and less dangerous method?
