9 Signs Your Partner Might Cheat On You, Backed By Science

There are a lot of ways a romantic partner can betray you (sorry), but cheating is arguably the worst. Unless you’re in an open relationship, you don’t want to even think about your boyfriend or girlfriend flirting with, let alone hooking up with, another person behind your back. Infidelity can break your heart and destroy a relationship, even a seemingly sturdy one. It’s also quite common – a recent 2017 study found that about 25 percent of men and 14 percent of women have admitted to cheating at least once in their lifetime, and that obviously doesn’t count people who don’t tell the truth.

It’s no wonder that so many of us are scared that our partner will cheat! This fear is made even worse by modern technology. Apps like Snapchat allow guys and girls to send photos to each other in a completely secret way that you’ll have a tough time finding. Sites like AshleyMadison.com exist for anyone to use. Dating apps like Tinder make it easy to find people who are just down to hook up. It’s a legitimate concern.

Of course, there’s no way to know for sure if someone is going to cheat on you, but there are some signs you can look out for. I’m not just talking about things like your boyfriend always deleting his texts, or your girlfriend always mysteriously disappearing every Friday night for a few hours. I’m not talking about traits that are backed by science as legitimate signs that one might cheat. Now, that doesn’t mean that your partner is guaranteed to cheat if they fit one of, or even many of, these signs. But it’s definitely something to consider! Here are a few signs that your partner might cheat on you:


Their Friends Cheat

The actions of your partner's friends can affect your partner as well - and if their friends all cheat all it's no big deal, they might do the same. Psychologist Antonio Borrello says that "having a social network that condones or supports infidelity" can influence your partner to cheat on you as well. It makes sense - if they see everyone else cheating and getting away with it, they might feel like they can do the same, or they might feel like that's just the way relationships are. If your partner has, like, one friend who cheated once, this probably doesn't apply. But if their close group of friends makes cheating a sport, or acts like it's nothing, beware.

They Don't Get Jealous When Others Flirt With You

According to one psychologist, a partner who doesn't seem to care if others are flirting you could cheat on you at some point. Your partner shouldn't be crazy jealous, someone who flips out if someone else so much as says hi to you (this could actually be a sign of too much testosterone, which is a common trait in men who cheat), but they should be a little protective of you in public. If they aren't, it could mean they feel indifferent about that sort of thing, which could mean they might cheat down the line.

Your Partner Is A Blonde Woman

Sorry to discriminate, but a study from CheaterVille.com once found that 42 percent of women who cheat have blonde hair. The reasoning behind that isn't clear, but hey... watch it if you're dating a girl with blonde hair!

They've Cheated Before

You know the saying "once a cheater, always a cheater?" Well, as it turns out, this is probably usually true. A recent study found that people who had cheated before were much more likely to cheat again - whether they cheated on their current partner or a past partner. It also found that someone who cheated in their first relationship was three times more likely to cheat again. This is probably because someone who has cheated before has gotten used to their bad behavior - so used to it, that they've just accepted that this is what they do. Of course, someone who cheated before isn't going to automatically cheat again. But it is a legitimate concern and not just a silly saying.

They Are Very, Very Attractive

Some of you might not be surprised by this, but one study found that conventionally attractive people were more likely to cheat on their partners. This is more than likely because super hot people attract more attention. They're given more temptation, and more opportunities to be with someone besides their partner.

They Listen To Rock Music

Well, this is really strange, but one study found that 41 percent of people who have admitted to cheating prefer rock and roll music over anything else. Why? I... have no idea. There isn't any reasoning behind it, apparently.

They Don't Have A Lot Of Other Close Relationships

Is your partner close to a lot of other people? Does she/he have a lot of close friends, or do they have good relationships with their family members? If it's a big no to all of those questions, they might be more likely to cheat. One psychologist says that, "poor family relationships and few friendships suggest he may not be good at bonding to people, including romantic attachments. If he hasn't had a romantic relationship for more than a year, there is no reason to think you will be the first." Your partner's relationships with others could be a big indicator of how they will be with you.

Their Parents Had A Bad Relationship

If your partner had parents who cheated on each other or who had a bad relationship, chances are good that they might treat you the same way. It makes sense, especially if they were exposed to a lot of what went on - they grew up seeing it happen to the two people closest to them. That's hard to ignore.

They Have Sex Performance Issues

Is your boyfriend having trouble keeping it up during sex? Well, that could be a sign that they might cheat. According to research, men are more likely to cheat if they have sexual performance problems. The study said, "People might seek out high-risk situations to help them become aroused, or they might choose to have sex with a partner outside of their regular relationship because they feel they have an 'out' if the encounter doesn't go well -- they don't have to see them again." Makes sense, unfortunately.
