How to Tell If Your Girlfriend Has Slept with Someone Else: 10 Signs

There is arguably no pain in the world worse than the pain of betrayal. If you think your girlfriend is sleeping with someone else, you’re probably feeling anxious, scared, angry, or a combination of all these emotions.

How to Tell If Your Girlfriend Has Slept with Someone Else

Before you confront her, though, it’s probably a good idea to make sure she’s cheating on you. Falsely accusing her isn’t going to do either of you any favors.

How do you tell if your girlfriend has slept with someone else? We recommend spying on her phone activity with a phone monitoring app. If she’s texting some guy you don’t know private messages or sending him personal pictures, she’s cheating on you.

This article contains two parts:

  • Using a phone monitoring app such as Cocospy to confirm whether your girlfriend is cheating on you – Part 1

The app is trustworthy. It’s used by over a million people worldwide to keep tabs on their loved ones. Cocospy has been featured on notable platforms such as PC World, Life Hacker, BuzzFeed, and CNET.

1.1 Cocospy gives you full access to your girlfriend’s phone activity

What can Cocospy do for you? It allows you to see what your girlfriend is up to – and who she’s communicating with – on her phone:

  • Read messages: Is your girlfriend texting or sexting with someone? Cocospy will help you to find out.
  • View call logs: You can see a list of the most frequent callers your girlfriend’s had recently. Are they people you know and trust? Or is an unknown stranger constantly in touch with your girlfriend?
  • Check social media activity: Has your girlfriend acquired a new lover on social media like WhatsApp? You can read her private messages to find out.
  • View contact information: What kind of people does your girlfriend know? A look at her contacts book will tell you. You can get information like contact names, addresses, job descriptions, and more.
  • See browser history: You can check your girlfriend’s browser history to get an idea of her current mood or personality. If she’s reading articles like “Is your boyfriend right for you?”, then you know something’s wrong.
  • Look at calendar events: Does your girlfriend have a date planned with someone in the future? She may have noted it in her calendar, which Cocospy can give you access to.

Cocospy gives you regular updates on your girlfriend’s phone activity. You can track her over a prolonged period of time – like several weeks if you have to.

1.2 Your girlfriend won’t know Cocospy is watching!

The best part about Cocospy is that it’s 100% undetectable. This is true for both iOS and Android devices.

If your girlfriend owns an iPhone, you can set up Cocospy remotely from any web browser. Cocospy for iOS is a web-based utility. You don’t have to download or install anything on her phone. Cocospy will work with your girlfriend’s iCloud account directly.

Because Cocospy for iOS is a remote app and it doesn’t work with the iPhone directly, it can’t be detected! You can use it without fear of your girlfriend finding out.

The Android version of Cocospy is a small app, less than 2MBs in size. You have to install it on your girlfriend’s Android phone before you monitor it. It’s still undetectable, though. How? After you install the app, you can hide it!

Cocospy for Android will run in the background without draining your girlfriend’s phone’s battery. The app is very small and not resource-intensive. The app icon is also hidden. Because of all this, it’s impossible to detect.

**Note: No remotely installed Android phone monitoring solution exists! You can’t spy on your girlfriend if she owns an Android smartphone without installing something on her phone. Be wary of fraudulent apps and services!**

1.3 You can set up Cocospy without your girlfriend finding out

Interested in setting up Cocospy to spy on your girlfriend’s phone? Here are the steps to follow:

1.4 What makes Cocospy a solid girlfriend tracker?

Why should you use Cocospy to monitor your girlfriend? Here are 4 compelling reasons:

  1. You don’t need to root or jailbreak your girlfriend’s phone

  1. You can trust the app

Over a million people from around the world use Cocospy. The app is trusted worldwide. Users include parents, people in relationships, and employers. It’s virus-free and doesn’t steal your personal information, unlike some of the other apps out there.

  1. You don’t have to pay a lot for it

Cocospy is available at an affordable monthly price. You can tell if your girlfriend is sleeping with someone else for the cost of a snack at a restaurant. Other spy solutions out there are far more expensive.

  1. The app can be used remotely and conveniently

You don’t need any tech skills to use Cocospy. You can set up the app with just your smartphone or computer – and operate it from any web browser. The app works remotely via the internet and, if necessary, can be uninstalled remotely.

Part 2: 10 Signs Your Girlfriend Just Slept with Someone Else

When your girlfriend slept with someone else – or has been doing so for some time – the signs will be obvious:

  1. She wasn’t home last night

If your girlfriend wasn’t home last night and comes up with flimsy excuses as to where she was, chances are she slept with someone else. If she’s not meeting your eyes or talking to you properly, it’s a sign of her guilt.

  1. You don’t connect properly anymore

Has your girlfriend maybe been sleeping with someone long-term? If the both of you don’t gel as you used to and if the intimacy has gone down, chances are she’s intimate with someone else now.

  1. She appears guilty

Does your girlfriend overcompensate with you out of guilt? Has she been extra nice to you lately, for example? Does she do all the chores or offer you help without complaining? She may have slept with someone else and is being extra nice to make up for it.

  1. She is emotionally absent

When you’re close to someone, you’re close to their emotions. Does your girlfriend appear detached from you now? Does she not feel the same way about you anymore? It could be that she’s lost interest in being with you.

  1. She doesn’t want to have sex

Are you having trouble convincing your girlfriend to sleep with you? And when you do sleep together, is it not as good as it used to be? If she’s holding back in some way, it’s because she could have made place in her heart for someone else.

  1. Your girlfriend is suddenly into her looks

If your girlfriend is suddenly trying to look good and dressing up – even more than before – then she’s trying to impress someone. This someone could be her new lover. Watch for other signs of behavior change like new clothes, new makeup, and the like.

  1. She has mood swings

Does your girlfriend have a lot of strange mood swings lately? Does she seem suddenly happy one moment and sad the next? It could be something triggering her, like deep feelings for her new lover.

  1. Your girlfriend doesn’t want to stay in touch

Are you having trouble talking to your girlfriend lately? If she doesn’t want to meet up as often as before or if she’s constantly spending time on her phone, it could be that she’s dating someone else and not just you exclusively.

  1. She’s always busy

If your girlfriend has no time for you suddenly, there’s a possibility she’s not really committed to your relationship. People always make time for the things they really care about, regardless of how busy they are.

  1. She’s confused

Is your girlfriend having a crisis of some sort? Is she having second thoughts about being with you? In this case, it could be that she’s found someone else to be with – and she’s comparing them with you.

Conclusion

Does your girlfriend exhibit any of the 10 signs she’s sleeping with someone else? If she does, it might be a good idea to use an app such as Cocospy to find out for sure. Once you’re sure, you can confront her – and decide whether it’s time to let her go.
