You may not realize it, but there are quite a few tell-tale signs that the person you're with is absolute garbage. Whether it's signs they have a side bae or signs that they're being unfaithful to you in other ways, everyone should know how to spot these red flags:

1. They won't let you anywhere near their phone

It's not cool to pry through every single message on your S.O.'s phone, but if they've been acting secretive about who they're been talking to, or what the notifications on their lock screen are, there's something they don't want you to see.

2. They ask you to do things and be things that you aren't

Are they suddenly asking you to fulfill some crazy fantasy? Or dress a certain way that's completely out of your style? Red flag.

3. They're on Tinder

Pretty self-explanatory. Nothing is more awkward than one of your friends matching with them.

4. They've become increasingly disinterested in you

Even though this doesn't for sure signal cheating (it could be your relationship dying, or a host of other reasons), it's important to pay attention to where their attention is—or isn't—in your relationship.

5. Lies have been adding up

Even if they're little white lies, a constant habit of lying from you or keeping things from you is a major red flag. It shows that your partner is accustomed to deceiving you.

6. They're really secretive or vague about their plans

Not sure what they've been doing after class or on the weekends lately? And they won't tell you? Hmm.

7. They stop posting about you completely on social media or untag themselves in your posts

Not everyone is big on social media, but if your boo is and has been throughout your relationship, and suddenly stops, that's sus.

8. There's a general sense that you aren't close anymore, for no apparent reason

Pretty broad, but if your gut is telling you that something's up, and you can't think of a good reason why, it's probably time to confront your S.O. about it.
