How to Tell if Your Girlfriend Is Texting Another Guy [Signs and Solutions]

So, something feels off. Her behavior has changed, but you can’t quite put your finger on it. There are no obvious red flags, but your stomach drops every time she smiles at her phone.

That weird “frozen” state feels exactly like this. You don’t want to cause drama, so you just sit there, doing nothing. But no matter how calm you look on the outside, inside, you can’t stop thinking about how to tell if your girlfriend is texting another guy.

And we’re here to help you with that.

Humans tend to follow certain behavior patterns, even when it comes to something as subtle as texting someone else while in a relationship. 

So, we’ve put together these patterns, plus a few tips, to help you figure out what’s going on and what to do next. 

How to Know if a Girl Is Texting Another Guy [10 Main Signs]

1. She’s Always on Her Phone

You’ve probably noticed how people love doomscrolling. If your GF can’t resist it, it’s concerning, but it doesn’t scream, “Your girlfriend texting other guys!”

Your alarm bells should go off, though, if she’s acting like a customer service rep on a 24/7 emergency line. Always ready to answer, never misses a single text, even in the middle of a conversation with you. She might not just be chatting with friends if her face gives off “finally you’ve texted me” vibes.

2. She’s Hiding Her Phone From You

You see how she’s doing it on autopilot—flipping her phone when you look her way, leaving it face down so you can’t see the notifications, or even shutting it off completely. This is a parade of red flags. Trust your gut on this one. Maybe it’s not texting another guy, but whatever it is, she knows you wouldn’t be okay with it.

3. She Can Never Let Go of Her Phone 

So, you’re reading our post on how to know if she’s texting someone else, and there she goes, phone in hand. She cooks with it in her pocket, sleeps with it under her pillow, and even keeps a power bank handy so she doesn’t have to leave it charging near you. It seems like she’s doing everything possible to keep that thing away from you.

4. She Has Changed the Password on a Phone 

When everything was OK, you had an “open phone policy” in your relationship or at least knew each other’s passcodes. Now, her phone’s locked with a new 8-digit code. If that sounds like your situation, and she has never been this private before, it might be worth asking yourself if there’s more going on behind her lock screen. This sign alone doesn’t mean she’s talking to someone else, but it could raise a red flag if you notice other unusual changes in her behavior.

5. She Hides Her Phone Screen From You

You know what gives off “girlfriend texting other guys late at night” vibes? Her microhabits, like hiding her phone’s screen from you. And we mean that both physically and technically. She might tilt the screen away from you. Classic move. Or, if she knows her way around her smartphone, she could enable privacy blur on notifications, change app icons, or mute specific contacts.

6. She Changes Her Texting Style

Her responses feel cold. They’re sharp, short, and sometimes even a bit aggressive. This could be because she’s too busy texting someone else or becoming emotionally detached from you—possibly because she now has someone else to invest her energy in.

7. She’s Deleting Chats

Most people (if not everyone) delete text messages occasionally just to free up some memory. Getting what we’re trying to say? If someone’s girlfriend texting other guys late at night, she deletes those texts daily or right after ending a conversation with someone. It happens 90% of the time. She knows her boyfriend wouldn’t approve of this.

8. She Changes the Subject When You Ask Her About Her Texts

…or even just hint you want to discuss something. You might be using a non-accusatory and respectful tone, but it doesn’t really help because she shuts down the conversation before it even begins. All you get from her is something like, “Oh, it’s nothing important” or “You’re overthinking things.” 

9. She Avoids Eye Contact

If you can hold long eye contact with someone, it means you trust them and feel comfortable being vulnerable around them. A girlfriend who’s texting other guys just won’t be vulnerable with you because it would eventually expose her lies, so she stops looking you in the eyes like she used to. She just can’t relax around you.

10. She Takes a Long Time to Text Back

You might notice how her texting habits have changed. She used to reply to your messages within seconds if she wasn’t really busy doing something. Now, she seems to be always busy whenever you text her. 

How Do You Know if Your Suspicions Are Correct

If notice two or more of these signs in her behavior, she might be hiding something. But, unless you’ve seen her texts with other guys, you can’t really tell if she’s romantically involved with someone else.

So, how to know if a girl is texting another guy for sure? One of the best ways is to get solid evidence, like her chat history. Let us show you how to do it without raising her suspicions.
