When she behaves in these strange ways, do not give yourself a false trust, she is definitely seeing another guy.

If your girl is doing any of these signs, it’s time to start packing your bags… According to relationship experts:

1. She’s Acting Like A GPS Tracker

If she’s started tracking your movements all of a sudden, then this could be the reason why. Is she suddenly extremely interested in where you’re going to be during the day, at what time, and for how long? Well, it’s not because she finds your activities fascinating, or even that she suspects that you’re cheating on her. The most likely explanation is that she’s trying to make sure you’re not around to catch her.

2. There’s Some New Sexy Underwear

Sexy underwear has a way of making them feel hotter and more desirable, as much psychological as it is a matter of appearance. Putting some lingerie on is a statement of intent. So if you spot a few pairs of lacy new things in the drawer (and you’re sure they’re not to spice up your relationship), it’s a good sign that she’s expecting to get frisky in another bedroom.

3. Her Fitbit Is Getting A Workout

If your lady’s usually the fitness freak, or she’s been talking for years about shedding some pounds, then that’s fine. But a sudden and unexplained interest in losing weight is not fine at all, especially if you’ve already told her numerous times that you love her the way she is. Chances are that slim new her is intended for a return to the dating scene.

4. Her Phone’s Getting More Love Than You Are

There is, however, a time and a place for this kind of thing. And when it comes to romantic relationships, there’s a definite line that can be crossed. If she’s doing it while you’re trying to have a romantic picnic, or it’s the first thing she grabs for in the morning instead of you, it might be time to literally and metaphorically pack things up. Clearly there’s someone on the other end that’s getting her undivided attention.

5. Her Friends List Is Full Of Strange New People

Some women, of course, are natural social butterflies and will be racking up new friends and fresh faces like it’s going out of fashion. In that case, it’s not unusual to see a couple of new names on their Facebook feed or commenting on their Instagram photos. If those new friends seem to be taking up a lot of her time, though, and she’s never talked about them or invited you to meet them, you’ve got a reason to get suspicious.

6. It’s No Longer “We”
For the first stage, everything is “we”. For the second, all you can talk about is “I”. But when you’re basically married, it then becomes “we” again. The two of you have basically morphed into one indistinguishable lump of a couple. That’s why when she starts saying “you” and “I” again, it’s time to get worried. This is stage four: she no longer thinks in terms of the two of you together, which might mean that she’s thinking in terms of someone else entirely.

7. Her Plans Don’t Include You

If her invitations have dried up, and you don’t even have something you absolutely have to come to or else in the next couple of months, then you’re in trouble. There’s three possible reasons: either your jokes have been terrible lately, or no-one in the world is having a birthday, or she’s planning to dump you. Or a fourth, even more terrible, option: it’s slipped her mind because she’s busy daydreaming about having someone else on her arm.

8. She’s Throwing Smoke Bombs

Most dudes should know what a smoke bomb is, but for those who are a little less underhanded than the rest of us, let us lay it out for you. A smoke bomb is basically any kind of misdirection that’ll deflect attention away from the real topic. We’re talking tantrums that come out of nowhere, counter-accusations, and completely irrational behavior.

Recognize any of those? You should, because it’s a classic move, straight out of the cheating-man playbook. Women are fully capable of doing the same, though, so you should be on the lookout. If a conversation or some innocent questions suddenly take a sharp U-turn, then you’ve gotten close to a painful truth – one that she doesn’t want you to know.

9. She Doesn’t Answer Certain Phone Calls When You’re Around

No, there’s only one real reason why she wouldn’t take a phone call: because you’re in the same room as her, and she doesn’t want you to overhear what she’s saying. Or who she’s talking to. And the only reason that might be is she’s organizing you a surprise birthday party, or she’s organizing some hot action for herself on the side.

10. If She Leaves The Room When The Phone Rings, Be Warned

You should read this kind of behavior as essentially saying that she doesn’t care about you anymore. She no longer has the decency to take her infidelity and keep it outside of the house, and she couldn’t give a flying penguin whether you know about it or not. Why would she be so brazen? Well, that’s a strategy in itself – to make you do all the dirty work and break up with her. So you’re the bad guy.

11. The Bedroom’s Now Just For Sleeping

Unless you’ve been married for forty years, no intimate relationship is complete without a healthy sex life. Sure, they slow down and get into a rut over time, but that doesn’t mean you’re still not enjoying each other’s bodies. Humans have needs, and sex is right up there for most people with breathing and eating. It’s a joy that few ever truly give up.

But if the interest stops dead there’s either a more serious relationship problem or she’s getting her kicks somewhere else. A month or so without getting jiggy isn’t a huge deal, but flat our refusal, night after night, is a bad sign. Sure, you could just be awful in the sack. But it’s more than likely it’s one of the other two options. Either one could be a symptom or a cause, and either one spells out T-R-O-U-B-L-E.

12. She’s Avoiding Your Questions

Everybody knows, deep down, that cheating on someone is wrong. Even the most heartless swinger can admit they’re harming the relationship by straying, if they look deep enough into themselves. But that’s the thing: a cheater will do whatever it takes to avoid looking into their feelings, because they know precisely that they’re not going to like what they find.

Worst of all for a cheater is talking to their partner about it, or having to face questions from them, because then the lies only add to the guilt. “What’s that?” she shouts over the timely clatter of washing up. “Just gotta go to the store,” she says, cutting you off mid-sentence. “Not now, The Bachelor’s on” – just as you are about to lay bare your heart. Sounds familiar? Time to start digging.

13. She’s Starting To Really Bring Up Relationship Problems

Every time she brings up relationship problems, consider how they’re being brought up. Sometimes, it’s true, she really is unhappy and is trying to give both of you a chance to mend things. But if the problems are coming thick and fast, and really very minor, then she could just be laying down the groundwork for a breakup. She could be justifying to herself the reasons why she’s cheating on you.

14. She’s Had A Big Makeover

After about half a year of dating, you don’t need to impress anyone anymore. You’re already in a relationship, so you can go back to being the flannel-wearing slobs you always were. That’s why any new changes in her appearance should set off the alarm bells. Any new clothes, and sudden obsession with doing her make up again, and she’s more than likely trying to impress a new man in her life.

15. She’s Started To Hide Her Phone

It might not just be her phone, either – it’s more than likely that she’s changed her password on her computer, and is hiding her diary. You’re probably going to start feeling like a parent, especially when you walk in the room and she starts quickly closing browser tabs. Trust us, she’s not watching porn, just flirting with someone you don’t know.

16. She’s Not Gazing Dreamily Into Your Eyes

Watch carefully when you talk to her, or ask her a question. There’s no need to be a fortune teller – just a simple glance away every time she answers you will be obvious enough. There could be other explanations, like if you live in a hummingbird farm, but the simplest is that she’s not telling you the whole truth. The whole truth being that she’s found another bed to lie in.

17. She’s Staying Late At Work. A Lot.

A regular office girl is bound to have these kinds of events every now and again, so if she’s late home a couple of times a year, there’s nothing to worry about. But if office functions and “lots of work” seems to come up with increasing frequency, you’d better check out her cover story quick smart with a couple of her colleagues. You might not like what you find.

18. She Picks And Picks At Everything You Do

If she’s started to pick and nag about everything you do, not just the annoying things. For some reason, you’ve copped an earful for putting the recycling in the wrong bin, like anybody even knows what the hell is the right one.

Want to know why she’s doing that? Well, it’s a pretty simple psychological trick. It’s a way of justifying to herself her cheating ways, and making them seem not as bad in comparison. People who are cheating on their partners, or are about to break up with them, will often find the slightest faults in every little thing that the other person says or does. It’s guilt, and it’s self-defense. She may be cheating on you, but at least she’s not destroying the planet by not recycling properly.

19.She’s Not Sharing With You

One of those buzzphrases that gets thrown around a lot these days is “emotional cheating”. It’s not just about the physical act anymore, but about having an intense emotional bond with someone else. A bond that might just be better and more fulfilling than the one they’re having with their partner. There’s one major problem with emotional cheating, though: how do you know when someone’s crossed the line?

Well, if she’s cheating on you, she’s forming these emotional bonds with someone else by opening up to them. She’s sharing her highs and lows, fears and dreams, and you’ll be able to tell that because she won’t need to share them with you anymore. She’s got a new sympathetic ear to whisper sweet nothings to, and maybe even share a bed with.

20. If You Smell A Strange New Scent On Her, She Might Be Straying

There’s two ways this can play out. Either she’s wearing a new perfume, or she’s picked up the light scent from another man. Neither of them are good news. The first, like new clothes, is a sign she’s ready to start flirting again. The second is even more obvious: it means that she’s actually been close enough to a guy for him to rub off on her. Let the mental images begin!

It really is a dead giveaway, so it’s kinda unfortunate that it doesn’t happen as much as it does in the movies. First off, she’s not going to be bathing in that guy’s aftershave, no matter how much she likes him. Secondly, it requires the nose of a police beagle to even tell the difference most days. Still, keep a nostril out for any changes. And if she starts smelling like weed and burritos, marry her.
