Early in a relationship is the best time to start learning about your potential significant other. You find out what you have in common and what you don't. You'll find out things you love and some you tolerate, but there may be some things you just shouldn't put up with. Here are a few warnings that this guy is definitely not the one for you.

1. He's hung up on an ex

He may be hiding it by saying they're just friends, or maybe they are just friends. But if he talks to her as much as or more than you, that's super sus. Like I'm all about amicable separations, but know where to draw the line.

2. How he treats his parents

You can learn a lot about a person by how they treat other people. But one good measure to judge upon is how a guy treats his parents. When you think about all our parents do for us, we should all be grateful. So if a guy treats his mom and dad with disrespect, that might be a red flag that he's not a great dude.

3. He doesn't take school/work seriously

I'm not saying everybody should have their shit figured out. That's a lot to ask. But if a guy doesn't have any goals or aspirations for his future and how he's going to live his life, you may want to take a step back. If he doesn't have himself figured out, he can hardly handle a relationship with another person.

4. He ghosts you regularly with no explanation

Alright, ghosting is so irritating for many reasons, but if it's fairly early in a relationship and homeboy can't find the time to call or shoot you a text for a day even to tell you that he's going to be busy, he's weak and natural selection is coming for him.

5. He's obviously not loyal

So maybe it's early and you guys aren't exclusive yet, but if he's seeing or talking to lots of other girls regularly and you're looking for something more serious, he's probably not the guy you're looking for.
