And if you need concrete answers, tools like Social Catfish can help you uncover hidden profiles, verify identities, and find the truth you deserve.
What Are the Signs of a Cheating Boyfriend?

Tip #1: His Phone Is His Baby
Yes, most people have their phones near them most of the time. Someone who is cheating is different. Their phone is always with them and within arm’s reach.
They never leave it in a common area and put it out of sight at night or even when they take a shower. They will treat their phone like a ‘baby’ that needs constant care and attention, as it is their connection to their cheating lifestyle.
Tip #2: Alerts Are Hidden
Most of us can view our text messages when we look at our home screen, even when our phone is locked. If your boyfriend has his phone’s settings set so that messages can’t be seen without a password, you are wise to wonder why.
Even if he does this, message alerts might still show the name of the person messaging him (even if the contents of the message aren’t viewable). If you see a name, nickname, or number you don’t recognize, ask him about it.
Tip #3: You Can’t Borrow His Phone
A cheater always has their eye on the prize – in this case, keeping their secret from you and not messing up their affair(s). If you need to borrow his phone (for instance, when yours is charging in the other room, or to take an impromptu photo) and he acts uncomfortable, this is more of a red flag than you think. His evident discomfort means that he is hiding something.
Tip #4: He Won’t Share His Password
Similar to the previous tip, if he hasn’t shared his password with you, then he probably has something to hide. While he might not be currently cheating, he could use his phone for things he doesn’t want you to know about.
This might mean he’s messaging girls through social media, getting flirty texts, looking at pornography, or more. He might also be keeping that boundary about his password so he can cheat in the future, without worrying about being caught.
Tip #5: He’s out a Lot
If he’s out a lot and gives complicated excuses as to why (errands or last-minute evening work events), there is a chance he is lying and meeting someone. While many people in relationships have outside friends and activities if he takes a lot of time from you as a couple, there might be a reason why. If he never answers your phone calls when he’s out, the risk that he’s cheating is even higher.
Tip #6: His Phone Apps
If you do use his phone, but he is weird about you seeing the apps on it, he might be hiding a dating or messaging app, such as Mingle2, OkCupid, Elite Singles, Christian Mingle, Skype, Match.com, or Clover.Â
Tip #7: Computer Search History
While many cheaters keep their phone locked and secure so they don’t get caught, you might have more luck looking through their computer. If you do gain access to his phone or computer, look through his internet history to view the sites he’s accessed.
Remember, while suspecting your boyfriend is cheating feels terrible, finding out the truth can help you decide what action to take next. Unfortunately, whether you have evidence that your boyfriend is seeing someone else or just a nagging suspicion, you owe it to yourself to find out.
If your boyfriend isn’t giving you the loyalty and security you need, then it is your job to take care of yourself. Many times people are afraid to confront their partner or ask to see their phone messages due to it leading to divorce or a break up.
However, if you believe your partner is cheating it is okay to ask them about it and ask to see their phone. While being overly jealous without reason can be excessive or unhealthy, healthy, trustworthy boyfriends want their partner to feel secure and happy.
A caring partner will seek to reassure you and ease your fears with openness and conversation. A cheater will get defensive and go on the attack, or makeup reasons why you can’t see his phone.
