Finding out your partner has been unfaithful is enough to knock the wind out of anyone.
It’s not just the act itself that hurts; it’s the way it completely flattens the trust you’ve spent years building. When someone is cheating, they usually don’t just come out and say it; instead, they start building a wall of excuses and half-truths to keep you from seeing what’s really going on.
These lies often follow a bit of a pattern, and if you’re hearing them more often than not, it might be that your gut is trying to tell you something. It’s a miserable position to be in, but knowing the kind of things people say to cover their tracks can help you figure out if you’re being told the truth or just being sold a story.
1. “We’re just friends.”
This is probably the oldest one in the book. It’s a way to explain away why they’re suddenly spending every spare minute texting someone new or staying out late with them. Now, there’s obviously nothing wrong with having friends, but when a friendship starts to feel like a priority over the relationship, something’s up. If they’re hiding their phone when a message pops up or get defensive when you ask how their day was with this person, they’re usually trying to mask a connection that’s moved way past being just mates.
2. “I’m working late.”
Work is the perfect cover because it’s the one thing most of us can’t argue with. We’ve all had those weeks when the workload is mental, but if those late nights start happening every single week without much to show for it, it’s a bit suspicious. If they’re suddenly impossible to reach during those extra hours, or they come home looking fresh as a daisy rather than knackered after a 12-hour shift, the maths doesn’t quite add up.
3. “You’re just being paranoid.”
This is a particularly nasty way to handle things because it turns the problem back on you. Instead of answering your questions, they make you feel like you’re losing your marbles. By calling you “crazy” or saying you’re “imagining things,” they’re hoping you’ll get embarrassed and stop asking. If you’ve got a feeling in your stomach that things aren’t right, don’t let someone talk you out of your own common sense.
4. “I need some space.”
We all need a bit of alone time now and then to recharge, but when someone suddenly demands space out of nowhere, it can be a way to create a gap for someone else to fill. It gives them the freedom to go where they want and see who they want without having to check in with you. If this “need for space” comes with a side of being secretive and acting like a stranger in their own home, it’s usually more about distance than it is about needing a bit of peace.
5. “My phone battery died.”
In 2026, nobody’s phone is dead for five hours at a time. Between car chargers, power banks, and every cafe having a plug, it’s a very convenient excuse for when someone doesn’t want to be found. If they’re “unreachable” for large chunks of the evening on a regular basis, they’re likely avoiding your calls because they’re somewhere they shouldn’t be. It’s a simple way to dodge questions in real-time so they can come up with a better story later.
6. “I’m going on a business trip.”
Much like the “working late” excuse, a trip away is a cheater’s best friend. It gives them a couple of days of being completely unaccountable. You’ve got to wonder why these trips have suddenly doubled, or why they’re being so vague about which hotel they’re in or who they’re meeting. If the itinerary seems a bit thin, and they aren’t keen on you giving them a ring in the evening, they might be travelling for pleasure rather than business.
7. “You’re the only one for me.”
Sometimes, when someone is feeling guilty, they go into overdrive with the romance. If they’re suddenly bringing home flowers for no reason or being way more affectionate than usual, it can be a way to overcompensate. They’re trying to convince you—and probably themselves—that everything is fine. While a bit of extra love is usually a good thing, if it feels forced or like they’re trying too hard to prove their loyalty, it might be a smokescreen.
8. “I’m not attracted to them at all.”
When you ask about a specific person they’ve been spending time with, they might try to shut it down by saying that person isn’t even their type. It’s an attempt to make you feel silly for even bringing it up. But the truth is, affairs aren’t always about looks; they’re often about the attention or the ego boost. Saying they “aren’t attracted” is just a way to make you lower your guard so they can keep seeing them under the radar.
9. “I was helping a friend.”
This one plays on your kindness. If they’ve been gone for hours and claim they were “sorting out a mate’s plumbing” or “listening to a friend’s breakup drama,” it makes you feel like the bad guy for being annoyed. It’s a brilliant way to hide where they’ve been because it frames their absence as an act of charity. But if these “crises” always seem to involve the same person and require a lot of one-on-one time, it’s probably time to look a bit closer.
10. “You’re imagining things.”
This is a classic way to shut down a conversation before it even starts. Instead of actually addressing why you’re worried, they dismiss your concerns as if they’re completely insignificant. It’s a way to make you feel like you’re being high-maintenance or exhausting just for noticing things have changed. If you find that every time you try to talk about your feelings, you’re told you’re overreacting, it’s a sign they’re trying to avoid the truth by making you feel like the problem.
11. “I’m just not in the mood lately.”
While it’s totally normal for your intimate life to have its ups and downs, a sudden and total drop-off can sometimes mean their physical energy is being spent elsewhere. It’s not always about a lack of desire for you; it’s that they’ve checked out emotionally, or they’re getting that intimacy from another source. If the bedroom has gone completely cold, and they’ve got no interest in even trying to reconnect, it’s a big shift that deserves an honest explanation.
12. “I’ve been really stressed at work.”
We all use work as an excuse for being a bit grumpy or distracted, but cheaters use it as a catch-all cover for why they’re acting differently. They use “stress” to explain why they’re being secretive with their phone, why they’re coming home late, or why they’re suddenly so distant. It’s a hard one to challenge because you don’t want to be unsupportive if they’re actually struggling, but if the “stress” only seems to kick in when you’re asking questions, it’s likely a shield.
13. “I bumped into them coincidentally.”
If you or a friend happens to spot them out and about with someone they shouldn’t be with, they’ll almost always claim it was a complete coincidence. They’ll say they just ran into each other and decided to grab a quick coffee, or they happened to be walking the same way. While the world can be small, “coincidences” like that don’t usually happen three times a week in the middle of a town they don’t even work in.
14. “I’ve always had that perfume/aftershave.”
A new scent is often a dead giveaway. If they suddenly smell like a different perfume or a brand of cologne they’ve never owned, and they try to tell you they’ve “had it for years,” they’re lying to your face. People don’t usually change their signature scent out of the blue unless they’re trying to impress someone new, or they’ve spent enough time around someone else that the smell has literally rubbed off on them.
15. “I’m just trying to spice things up.”
Sometimes, a partner who’s cheating will suddenly want to introduce a load of new moves or ideas into your intimate life. While wanting to spice things up can be a great sign of a healthy relationship, if it feels completely out of character or like they’ve suddenly developed a whole new skill set overnight, you have to wonder where they’re getting the inspiration from. Often, they’re just bringing habits from their affair back into their marriage.
16. “They’re like family to me.”
By claiming someone is “like family,” they’re trying to make any sexual suspicion look gross or ridiculous. It’s a way of saying, “How could you even think that? It would be like dating my cousin!” It’s a very effective way to make you feel guilty for even having a wandering thought about it. But remember, real family friends are usually people you’ve known for years and who have a place in both your lives, not a new person they’re suddenly obsessed with.
17. “I’ve been thinking about our future.”
Cheaters will often start talking about big future plans, like a massive holiday next year or finally renovating the kitchen, to give you a false sense of security. It’s hard to believe someone is planning to leave or is seeing someone else when they’re talking about where you’ll be in five years’ time. It’s a clever way to keep you from looking at what they’re doing right now because you’re too busy looking at the “future” they’re promising.
18. “I would never cheat on you.”
The more someone insists they “would never” do something, the more you should probably wonder why they feel the need to keep saying it. Most people who are faithful don’t feel the need to constantly remind you that they aren’t a cheater; they just live their lives. When the denials are unprompted and a bit too loud, it’s often because their conscience is working overtime, and they’re trying to talk themselves out of the guilt.
