So that guy you met at the bar, that nice partner in your chem class, or my personal favorite, the cute boy from work, turns out to be something more than just a friend—great! You start dating, and somehow you realize that there are a few things you do that differentiate your boy (or girl) from everyone else. Here are the nine ways you know they're on your mind:

1. Every song on the radio is about them.

From "Boo'd Up" to "no tears left to cry," every song you hear somehow rings true to your boo. You're singing along and picturing them in your head, and you can't help but to smile or text them that you're thinking about them. Sometimes even certain songs that you two listened to together can bring back memories as well.

2. You add their last name to your name.

This one is something that really doesn't make a lot of sense... it's not like you're getting married tomorrow, right?! For some reason, adding their last name to your name is kind of like trying on a pair of shoes; you're just putting them on for size. It's also just fun to hear your name with someone else's and laugh.

3. You imagine what your kids would look like.

While this one is a little weird, you make up an imaginary family in your head. Not necessarily always thinking it'll ACTUALLY happen, it's just fun to toss the idea around in your head.

4. You leave anchors at their place.

From your earrings to your jacket, you're constantly leaving little reminders that you were there and that he's yours. Back off, ladies! It also gives you an excuse to see them again and, well, obviously that's what the end goal always is, right?

5. You come up with any reason to see them.

You notice they get to the office 15 minutes before you usually do? Well, now you know to get there 20 minutes early. You go out of your way to "accidentally" run into them places... it's not a coincidence, boys, that we were just at the grocery store when you were and just happened to get gas as well. But hey, while we're here, wanna grab coffee?

6. You take hella pictures because you want to use them on social media.

Trust me, there's already an album with his name on it, and he's already popping up on your VSCO. Boys, if you get on the Insta, KNOW that she's serious about you. We don't just put every guy we've talked to on our Insta, don't you know. We also love seeing your cute face, so we want to capture it and use it as our wallpaper on our phone, laptop and every device under the sun.

7. You'll jump at any opportunity to "borrow" their clothes.

My boyfriend always smells amazing, and if you're anything like me, you'll do whatever you can to sneak a sweatshirt or a t-shirt here and there. There's no way he NEEDS 27 sweatshirts of his favorite football team, and he most likely won't mind that you want to wear one.

8. You'll stalk all their exes.

You want to know who he's been with and what they look like. It's not really so much of a competition because he's with you now and not her, but secretly you're curious. Is he into blondes? Brunettes? Tall girls? Short girls? Who's that girl in that picture from 2015?

9. Come up with nicknames that are unique to them.

Babe, baby, etc. are all fine pet names, but why not be a little creative? You'll start making up nicknames for him based on his style, personality, inside jokes or anything else that reminds you of him. Just don't start calling him things like "babyface" around his friends, or he might get a little mad.
