If you suspect your partner is cheating on you, you could say "cheatersayswhat" and see if they say "what?" back. But there's a better way. All you have to do is pay attention to how they use their phone.

If you're one of those annoying "moral" people, you don't feel comfortable snooping on your partner's cell, secretly reading their texts and scanning through their missed calls. Well, good news, goody two shoes. You don't have to resort to violating someone's privacy to figure out if they're unfaithful.

Here are five red flags on your partner's phone that show they might be cheating.

1. They won't share their password.

Let's say a situation comes up where you forgot your phone, or it's dead, or it was plucked out of your hand by a hungry falcon. You grab your partner's phone and ask for the password, and instead of giving it to you, your partner insists on personally unlocking the screen. Why? Is your partner hiding something? Does your partner not trust you? And why are falcons such jerks?

2. They get push notifications from dating apps

If your partner gets a notification that they "have a new match" on Tinder, or "have a new message" from someone on OKCupid, or "scheduled a bone session" on OneNightStander, that should be a little concerning. Yeah, we all forget to turn off push notifications from time to time. For example, I downloaded a daily quiz show app a month ago, have only played it twice, and still haven't turned off the notifications. But if you're in a serious relationship, it's assumed you won't still be prowling on dating apps. Especially OneNightStander.

3. They don't take calls in front of you

We all take private calls sometimes, but if your partner's making a habit of taking private calls, then your partner might be making a habit of calling someone to get in their privates.

4. They never leave their phone unattended

Many of us are hopelessly addicted to our phones, checking the same websites ad nauseam, playing silly games very seriously and hoping for a new text message like a present from Santa on Christmas morning. But at the same time, everyone leaves their phone unattended once in a while. If your partner clutches their phone like Gollum clutched The One Ring, it's fair to wonder why your partner thinks their phone is so preciousssss.

5. The background is a photo of them with someone else

This one should be pretty obvious. I mean, look, it's normal for your partner for have friends. Group photos are cool. A photo of your partner with a family member, cool. A photo of your partner with a celebrity, like John Krasinski or Emily Blunt, cool. But if the background photo is of them with a person who is a potential candidate for dating, not cool. That's a bit weird. Especially if they're getting all touchy-feely and it could double as an engagement pic.

If you see any of these red flags, you should talk to your partner and see what's going on. Maybe your partner is cheating on you, or maybe it was all just one big understanding. At least now you have some tools to find out without violating their privacy. And if this doesn't work, you can always saying, "cheatersayswhat."
