Many relationships have their ups and downs, and trust issues are often a big part of that. Some couples start out with doubts, while others have trouble trusting because of things that happened in the past.
If you’ve ever had a gut feeling something isn’t right, you’ve probably done whatever you could to find out the truth.
Social media makes it harder to trust

Social media and smartphones have made it easier for people to be sneaky. Cheaters can hide behind DMs and private accounts, and if you don’t know someone’s phone password, it can make you feel even more suspicious.
Some women snoop through their partners’ phones

Some women get creative when they suspect their partner might be cheating. They’ll check phones, computers, or even emails for clues. Some even wait until their boyfriend falls asleep and use his face to unlock the phone. Crazy, right?
Many women today are sharing tricks to catch cheaters

When you feel like something’s off, you’ll go to great lengths to figure out what’s really going on. Nobody wants to feel like they’re being played, so it’s no surprise that women are coming up with ways to catch cheaters in the act.
Now, if your man has his own car, here’s a new trick for you

If your partner drives a lot, you might wonder who else has been in the car. Even if they try to hide the evidence by cleaning up and “covering their tracks,” one TikTok user shared a clever way to figure it out anyway.
The trick is all about the passenger mirror

The TikToker points out that most women use the mirror to check their hair or makeup. The idea is simple: if another woman has been in the car, she might use the passenger-side mirror.
She shows how to set it up

She flips down the visor and opens the mirror, but she doesn’t close it. The trick is to leave the mirror open. If someone else comes into the car and uses it, they’ll likely close the mirror before flipping the visor back up. Later, you can check — if the mirror is closed, it might mean a woman was there.
While some people thought this was smart, others said it was silly.

Some pointed out that the visor could move if the car hits a bump or pothole, so the mirror might close on its own. There are plenty of explanations that don’t involve cheating.
It might not even be a girlfriend

Other TikTokers said the person using the mirror could be a female friend or family member, like a sister, mom, or grandma. It’s not always fair to jump to conclusions.
Guys use the mirror too

Who says only women use visor mirrors? Some guys check their hair or face in the mirror, and they might also let their friends drive their car.
Finally, one person said what we were all thinking

One person summed it up perfectly: if you don’t trust someone, the relationship might not be worth it. If you’re setting traps and playing detective, it’s probably time to rethink things. A healthy relationship shouldn’t feel like this.
At the end of the day, trust is the real key to any relationship. But if you’re feeling suspicious, a little mirror trick won’t hurt — just don’t forget to keep it classy, not crazy!
