Is He Cheating? How to Be Your Own Private Investigator

You don’t need to hire a private investigator to find out if your boyfriend is cheating on you! Here are 12 signs he’s involved with another woman. It’s time to stop asking “Is my boyfriend cheating?” and start preparing for the truth.

Why do you want to know if he’s having an affair? Because “you can’t change what you don’t acknowledge,” says American television personality, psychologist, and author Dr Phil McGraw. The sooner you figure out if your boyfriend is cheating on you, the sooner you can rebuild your relationship. Or get out of it. Give yourself time to be sad and grieve – I know that it can feel confusing and difficult to know if your boyfriend is cheating. Especially if he doesn’t admit it or tries to make you feel like you’re crazy. But the more evidence you gather, the more you’ll understand about how affairs happen, why, and how to recover. That’s why I researched 12 warning signs a boyfriend is cheating, with help from an experienced private investigator….

“People cheat out of boredom, to make their lives more like James Bond,” says private investigator and author Guy White. “An affair becomes that excitement they don’t get from their jobs. But it’s not always sexual. Some of it is just getting away with something. People like the rush and excitement of sneaking around.”

One of the most obvious ways to know if he is cheating is to look for unaccounted-for time. For example, does he go to the gym every day for a long time – but he isn’t losing weight or getting fitter? Is he at work for longer than usual, or does he disappear for long lunches during the day? Maybe he suddenly has to go to work in the middle of the weekend or at night, or his phone is turned off for long periods of the day.

More tellingly, does he discourage you from going to his gym or workplace? If he doesn’t want you to know where or with whom he spends his time, he could be hiding something.

When you’re looking for clues about your husband or boyfriend’s faithfulness, remember to look at the big picture. If you hired a private investigator to help you find out if he is cheating, she wouldn’t bring back one or two clues. She’d bring several signs that he’s being unfaithful.

Read each of the following tips for investigating your husband or boyfriend’s behavior, and then step back and look at the whole picture.

Is He Cheating? 12 Ways to to Be Your Own Private Investigator

You are not alone. Take a deep breath, and know that no matter what unfolds in your relationship, you are loved. You will survive, and you will be better, stronger, and happier than you’ve ever been.

But first, you must learn and face the truth.

9 Ways to Know if Your Husband is Lying About Cheating is one of my most popular articles – but after reading a book called The Cheat Sheet: A Clue-by-Clue Guide to Finding Out if He’s Unfaithful, I realized that there are so many ways to be your own private investigator (PI). If you’re plagued by the “is he cheating?” question, you don’t need to hire a PI. Here’s how to be your own detective, and how to find clues that your husband or boyfriend is cheating on you…

These tips for being your own private investigator are from The Cheat Sheet by Rea Frey and Stephany Alexander. The link to the actual book is a the end of this article – after my “7 Additional Signs Your Boyfriend is Cheating on You.”

1. Install a GPS in his car or cell phone

“This is truly one of the most effective tools for figuring out whether he’s going and what he’s doing,” write Frey and Alexander. “Instead of stealing his phone when he’s not around or following him around like a stalker, you can track his activity remotely with a small stealth device.”

gps tracker is he cheatingA Personal GPS Tracker doesn’t require any special knowledge or instructions to use. You just put it in the vehicle, suitcase, clothes, or anything you want to track.

If you’re not comfortable with GPS technology to track his whereabouts, consider bluffing. Instead of asking, “Are you cheating on me?” you might say, “I know from the GPS on your phone or car that you are spending time in places that you aren’t telling me about. I know you’re cheating, and I’m giving you this opportunity to ‘fess up. It’ll be worse for you to lie about cheating than to just come clean right now.”

While most men who cheat will lie or deny the truth, some will confess. Bluffing might be the key to finding out if he’s cheating without hiring or becoming your own private investigator.

2. Check his cell phone records

Do you have access to his online or print cell phone bills? A private investigator would look at those records to find out if he is cheating.

“To obtain cell phone records, you normally need the owner’s social security number, last name, cell phone number, and his password,” write Frey and Alexander. “If you know this information, you can set up an online account through his carrier. If he already has it set up this way but you don’t know his password, you may be able to reset his password so you can log on.”

Remember that password alerts are generally sent to his email address, so you would need to check his email if you reset his password.

As I write this, I wonder if it’s worth this much effort. If I suspected my husband was cheating and lying to me – and especially if I had to become my own private investigator to find out out truth – I’d be tempted to just walk away. Why would I stay with a man I didn’t trust, a man I believe is lying to me about cheating?

That said, however, I know that the truth sets us free. When one of my readers asked is my wife having an affair?, he said he just needed to know whether or not she was cheating, for his own peace of mind.

So, let’s keep learning how to be a private investigator…

3. Learn the front-tail tactic

Here’s an interesting tip for detective work from The Cheat Sheet: A Clue-by-Clue Guide to Finding Out if He’s Unfaithful:

Is He Cheating on You? How to Be a Private Investigator

“Instead of a traditional tail that involves following someone in a car from a safe distance, you actually drive in front of the car you are following. This works best if the person is suspicious of being followed. Get in front of the car and pay close attention to where he is by using your rearview mirror. He will never suspect being followed. This tactic, often used by private investigators, takes a bit of practice to master, which is why GPS is often most effective.”

4. Look for hidden decoys when you ask him questions

This isn’t necessarily a private detective’s tip for finding out about an affair, but it’s a great way to learn how to read your husband or boyfriend’s behavior. If you think he’s cheating with someone specific – such as a coworker or neighbor – ask him about her. Watch how he responds. Does he seem edgy or defensive? Nervous or uncomfortable? If he makes fun of you for bringing her up, he could be hiding his guilty feelings about cheating.

An example of a “hidden decoy” is something that throws you off the scent. For example, he may change the subject when you ask questions. Or, he may get his friend to cover for him (eg, “Josh and I are playing poker in the cabin in the mountains, where there’s no cell phone reception.”).

5. Is he cheating? Listen to your intuition

Hiring a private investigator may confirm your suspicions…but your gut feeling that he is cheating on you is the most telling sign.

Further, as Guy White said at the beginning of this article, people like the excitement and rush of sneaking around and feeling like they’re getting away with something. Hiding his affair  is part of the thrill. If you left him and he made an official or formal commitment to the woman he’s cheating with, he’d be bored soon. He’d start cheating on her, and she’d be where you are now.

6. Build your case before confronting him

“When you have photos, video, text messages, emails, or other evidence and then you confront him, there’s no way for the truth to be denied,” write Frey and Alexander. “It makes the lies disappear and causes him to confront the truth head on…and if you are married or have children and are going to use infidelity as grounds for divorce, it is important to obtain concrete facts for divorce court.”

Before you ask him if he is cheating on you – or before you accuse him or confront him with the evidence you gathered by being your own private investigator – prepare yourself emotionally. Remember that he may become defensive, extremely angry, or deny the whole affair. He doesn’t want you to know he’s a cheater, and he will say whatever it takes to avoid telling you the truth.

6 Quick Tips for Being Your Own Private Investigator

Here’s a step-by-step guide for investigating your husband or boyfriend’s behavior:

  1. Tell him you’re leaving for the weekend, then stake out his house. Rent a car or borrow a friend’s.
  2. Install a Real Time GPS Tracker in your boyfriend or husband’s car. Put it near the dashboard or steering wheel, or even on the outside of the car.
  3. Prepare to do a lot of waiting! Being a private investigator involves hours of watching closed doors and empty cars.
  4. Place a voice-activated digital tape recorder in a hidden place, such as under a bed or his car seat. Record all conversations, and make sure your device has a large memory. The SpyGear Audio Recorder is a bestseller on Amazon.
  5. Check his voicemail and email messages regularly – not just once. Make sure you save them by downloading or sending them to your own voicemail or email.
  6. See what social media sites he’s on, and pay attention to his Facebook account.

Being your own private investigator to answer the “is he cheating?” question isn’t an easy task. You may feel like you’re spying on a man you love…and the truth is, you are. You suspect him of betraying you.

This isn’t a great place to be in a relationship, and only you can decide if it’s worth continuing.

 7 Additional Warning Signs Your Boyfriend is Cheating

An author shared what she learned after her husband had an affair in a book I read several years ago. I adapted her wisdom into these “signs your boyfriend is cheating.” But, you need to remember that every relationship is different, and not all men have affairs the same way.

1. Your own instincts: if you suspect he’s having an affair, then he probably is

Generally speaking – in most cases – if a girlfriend suspects her boyfriend is having an affair, then he probably is cheating on her. Why? Because she’s picking up on the cues and clues that reveal his behaviors and actions. She’s tuned in to who he is and what he’s saying without words, which can reveal what he’s doing when she’s not around.

2. Examine the reasons you think your boyfriend is unfaithful

Is he working or staying out late, getting private phone calls, or talking about a certain person all the time?

It’s important to look at those suspicions and determine if they’re valid. It’s also important to separate your own personal issues from your boyfriend’s actions and habits.

For example, if you think your boyfriend is cheating because your last relationship ended because of infidelity, then you be hyper sensitive to possible signs of an affair. Sometimes we’re suspicious of our boyfriends because of our own past experiences and issues.

3. Your relationship with your boyfriend

If you and your boyfriend aren’t emotionally or physically connected, then he may be looking elsewhere for love. Are you physically and emotionally intimate? Do you communicate with your boyfriend? Is he indifferent to family events or activities, such as anniversaries, birthdays, or holidays? Is he more secretive? Those signs may indicate that your boyfriend is cheating on you. I know how hard it is to admit the truth, but you need to be honest with yourself before you can decide if you want to put the effort into your relationship.

4. Evidence of cheating

Signs of an affair are often found in bank statements, credit card statements, email messages, text messages, Facebook accounts, or even car mileage. It may feel like you’re spying on him, but sometimes the only way to find out if your boyfriend is cheating is to dig into his life.

5. Changes in your boyfriend’s behavior, tone of voice, and habits

Warning signs of an affair can include nonverbal body language, verbal statements, and emotional reactions to questions. Is your boyfriend suddenly more attentive than usual, concerned about his appearance, wearing a different type of underwear, trying a different cologne, or ultra-clean when he gets home (from a recent shower)? A sudden change of behavior – such as leaving work early or late – could be a sign that your boyfriend is cheating on you.

6. Your boyfriend’s confession

Men (and women) who cheat don’t like to admit they’re having an affair. You may see signs of cheating long before your boyfriend tells you the truth. Your boyfriend may deny it, and you may be afraid to bring it up because of the effect it’ll have on your marriage. However, the sooner you talk about it, the better. Describe why you think he’s cheating on you, and ask him outright if he’s cheating. Ask him to be honest with you.

7. Evidence of cheating from a private investigator

On 8 Signs Your Boyfriend Doesn’t Love You, a private investigator commented that he’s often hired by wives who think their husbands are cheating. If you can afford it, consider hiring someone to follow your boyfriend. If he can’t stop lying to you and covering up his affair, then you need to get serious about discovering the truth.

The most reliable sign your boyfriend is cheating is your own instinctive feeling. What makes you think he’s having an affair? You may recognize none of these warning signs, yet know deep in your gut that he’s cheating.

What to Do Next

  1. Dear Unkno,

    It sounds like your husband is playing mind games with you! He’s not being honest or directly answering your questions. He’s dodging your questions and putting the onus back on you.

    I can’t tell you if your husband is cheating – and all the tips I have on how to be a private investigator are in the article above!

    But I do have a question for you:

    What are your gut instincts telling you about your husband’s time in the shed, and his answers to your questions?
    What do you know about him and your marriage that you’re not willing to face or accept?

    The Most Common Signs of a Cheater – From a Wife’s Perspective

    It’s important to remember that you can’t change your husband. The only person you have power and control over is yourself – and the good news is that you can change your life! If you could change one thing in your life and marriage right now, what would it be? Pick something that you actually have control over, such as how you respond to your husband’s behavior.

    What is something you have control over, that you can change in your life or how you interact with your husband?

  2. My husband stays out in his shed for long periods of time usually don’t come inside till 1 _2 am. He always tells me he’s working on a project or fixing something.

Iv have asked him if he is cheating on me and he always respond with who like I’m supposed to tell him her name. That itself is a clue for me.. then shout out how crazy I am. I need help start calling me names. Could it be possible that he is cheating.? He doesn’t let me touch or go near his phone. It’s always with him never laying around. I hear him whispering at times . When I approch him he says I’m hellusinnating. I’m so confused at times. He also tells me if I felt he was cheating I would have left him already at this point I’m confused. Please help
