“I don’t know why they call it adultery, there is nothing adult about it…”Patrick Scheidegger, 2023
These indicators aren’t meant to be alarmist but if your gut is trying to tell you something, they could prove useful.
Most of us tend to give our partners the benefit of the doubt as far as fidelity goes. But the truth is, signs of cheating do exist. In fact, according to a 2016 survey, one in four married and cohabiting young adults admitted to cheating, while only half confess.
You probably know the obvious signs of cheating, like lurking on dating sites long after getting into a relationship or always coming home late without a solid excuse. But in order to really ID a cheater, it pays to watch for subtle signs that aren’t as overt.
The following indicators aren’t meant to be alarmist—almost all of them can have alternate explanations—but if your gut is really trying to tell you something, they could prove useful.
Your relationship started as an affair
For some people, there is some truth to the saying “once a cheater, always a cheater.” John, 44, says he should’ve seen it coming when he got into a relationship with a married woman. “We were good in bed together, but she enjoyed being good in bed with others, too, apparently.”
They regularly accuse you of cheating
Beyond being classic projection, this tactic serves two purposes, says Healing Infidelity Coach Caroline Madden, LMFT. It puts you on the defensive so you don’t have the chance to consider the opposite possibility, and it makes them look so anti-cheating that they couldn’t possibly do it to you. It could also be a genuine reaction to them realizing that since they got away with cheating, you probably could too.
They’re taking out a lot of cash
Cheaters often use cash when they take their secret partners out so that their S.O.’s can’t track where they’ve been, says Rhonda Milrad, founder and chief relationship advisor of Relationup. But if you share a financial account, what you can track is a spike in ATM withdrawals.
They’ve suddenly got new sex moves
Of course, it’s possible they’ve just been doing their research—in which case, great if you’re into it—but other signs of cheating combined with a very noticeable change in sex routine could mean they’re picking up those new techniques from someone else and discovering new things they like, says Milrad.
They’re suddenly hyper-critical of you
Cheaters will sometimes try to justify their actions by making their relationship out to be so bad that they had no choice, explains Madden. She typically sees this happen in situations where the cheater feels they’re in love with their cheating partner, since they have a sense that their affair is happier than their relationship.
Your typical relationship issues seem to disappear
Madden’s clients are often surprised to find their partners are cheating because they thought everything was going well around the time the infidelity started. But sometimes, the reason things are looking up is that the needs that weren’t met in the relationship are being met elsewhere.
They’re paying more attention to their looks
If your S.O. is once again hitting the gym, buying new underwear, or taking a newfound interest in shopping, they could be in an early stage with someone else, says Madden.
They forget what stories they’ve told you
If your partner frequently starts stories with, “Did I tell you this already?” it could mean they’re having trouble keeping track of multiple confidants, says psychologist Colleen Long, PsyD.
They’re confiding in you less
Becoming less inclined to discuss problems with you could be a sign that your partner’s been venting to someone else, says Long. Even if they’re not sleeping with anyone else, this could point toward emotional cheating.
They keep strict tabs on your schedule
Lauren, 33, says her ex started to ask when she was coming home from work more often when he was cheating. Now, she sees he was trying to figure out when he and his cheating partner would have the place to themselves.
They have random new interests
“My ex had been content to listen to about eight songs, total, during our entire time together,” Julie remembers. “A bunch of new CDs without any writing to identify their contents—and a sudden interest in a whole host of new music—was due to the influence of this new partner.” Attachment to a particular place can especially be a giveaway: Julie’s ex insisted on joining a gym because of a climbing wall when he didn’t even climb. It turned out his secret girlfriend was a member.
Cheating was accepted in their family
Looking back, John thinks his ex’s parents should’ve been a clue. “She came from a family where her mother and father both cheated on each other and she told me that,” he says. “But her parents were still married. So they set an example for their daughter to follow.”
They get irate when you try to confront them
Someone who hasn’t cheated will likely have a good explanation for their suspicious behavior and do what it takes for you to feel confident. A cheater, however, may get defensive because you’ve blown their cover, says Milrad. “It is very common for cheaters to deflect responsibility and get irritated by your questions. They often try and shut you down and even criticize you for being too controlling or suspicious.”
