Finding out you’re not the only one in a relationship is never a fun experience, and that’s putting it lightly.

If your gut is telling you something’s off, it’s worth paying attention, especially because some people are way better at hiding double lives than you’d think. Whether they’re being vague about their schedule, dodging certain topics, or always acting suspiciously available yet unavailable at the same time, here are a few warning signs you might unknowingly be the other woman.
1. You never go to their place.

They’ve been to your place plenty of times, but their home? It’s practically a mystery. Maybe they always make an excuse about it being messy, or they say they’re “never home much anyway.” Whatever the case, if you’ve never stepped foot inside, you have to wonder: why? People in relationships with nothing to hide usually don’t have a problem letting you see where they live. If their place is off-limits, there’s probably a reason for it — and that reason might be another partner.
2. Their phone is a no-go zone.

If they’re constantly flipping their phone screen down, getting weirdly tense when they get a notification, or acting like handing over their phone is the same as handing over classified government documents, something’s up. Someone who’s juggling more than one relationship has to be careful with their messages. If they guard their phone like their life depends on it, you have to ask yourself what exactly they’re hiding.
3. You’ve never met their family or friends.

It’s been a while now, and you still haven’t met a single close friend or family member? That’s not normal. Even if they claim to be a private person, most people naturally introduce their partner to someone in their life. Keeping you separate from the people who know them best makes it easier to keep their double life going. If their inner circle has never heard your name, there’s a good chance they’re keeping you a secret for a reason.
4. Their schedule is weirdly rigid.

They’re only available at certain times, never respond past a specific hour, and always have a perfectly rehearsed reason for why they can’t see you on certain days. It’s almost like they have a second life… because, well, they probably do. Sure, some people have busy jobs and commitments, but if they never once switch things up to make time for you, it could be because they have someone else they need to “schedule around.”
5. You never go out in public together.

If all your time together is spent indoors or at places where they’re unlikely to run into anyone they know, ask yourself why. A healthy relationship involves going out, doing normal couple things, and being seen in daylight. But if they’re always steering you toward low-key, out-of-the-way locations or straight-up avoiding public outings, it’s probably because they don’t want to risk being seen.
6. They avoid social media like the plague.

Some people just aren’t big on social media, and that’s fine. But if they’re active online yet refuse to acknowledge you in any way, that’s a red flag. No tags, no mentions, no pictures together, almost like you don’t exist in their world. Worse? If you find out they do have a social media presence, but you weren’t supposed to see it. That’s usually a sign they’re keeping different parts of their life separate. And you know what that means.
7. You don’t actually know much about their life.

Think about it — how much do you really know about them? If all your conversations are surface-level, and they never let you in on the details of their daily life, that’s intentional. Someone who’s being honest about their life doesn’t need to keep things vague. If their job, family, or routine always seem strangely blurry, it’s probably because they’re hiding something — or someone.
8. They always seem just out of reach.

They’re emotionally available sometimes, but not enough. When you need reassurance, they’re distant. When you start asking too many questions, they disappear for a while. They keep you hooked, but never fully in. That’s because they’re managing multiple relationships and don’t have the emotional bandwidth to give you what you need. If you feel like you’re constantly chasing a connection that never quite solidifies, it might be because you’re not the only one in the picture.
9. Their stories don’t always add up.

One day they say they were “working late,” but a few weeks later, they slip up and mention a night out with friends on that same date. Little inconsistencies in their stories are a huge warning sign. People who are juggling relationships have to keep track of a lot of lies. If you start catching them in contradictions, pay attention — it probably means they’re hiding something big.
10. You feel like something is off.

Your gut is rarely wrong. If you have a nagging feeling that something about the relationship isn’t right, trust that instinct. Most people who find out they were the other woman later admit they knew something was off but ignored the signs. When things feel too secretive, too restricted, or too controlled, it’s worth asking yourself why you’re the only one being kept in the dark.
11. They disappear at key moments.

Valentine’s Day? Suddenly busy. Christmas? “Family stuff.” Their birthday? “Keeping it low-key this year.” If they’re dodging major holidays and life events, it’s likely because they’re spending them with someone else. Sure, people have commitments, but if they’re always unavailable on the dates that actually matter, you have to wonder why it keeps happening. Chances are, there’s anything but an innocent explanation.
12. You can’t leave anything at their place.

Sometimes they’re showering you with attention, and other times they seem emotionally distant, like they’ve just checked out. You might feel like you’re always chasing their affection or trying to prove your worth. That inconsistency is a huge red flag, as someone juggling more than one relationship will only give you as much affection as they can get away with without risking being caught.
13. You can’t shake the feeling that you’re a secret.

At the end of the day, relationships should feel open, honest, and natural. If you constantly feel like something’s being hidden, you probably are the hidden part. If they act like they care but keep you separate from their real life, it’s only natural to wonder why it feels like you’re a giant secret. Sadly, in most cases, it’s because you are, and that’s a situation nobody deserves to be in.
