Chemistry has been used as a catch-all phrase to describe a certain je ne sais quoi in relationships. It’s almost like being in a fairy tale movie where things seem too good to be true: the conversations just flow, your jokes click with each other, and the physical and emotional attraction is palpably strong.

Nothing quite compares to the feeling of the intense chemistry you can share with someone, but it’s not something that we always consciously know. Here are some signs to help you understand if you share intense chemistry with someone:

1) You Can’t Keep Your Hands Off Each Other

To the two of you, even the smallest physical space must be closed. There’s just something about touching them that makes you feel connected and loved.

When you’re next to each other, you can’t help but hold hands or bump feet under the table. When you’re cooking next to each other, you constantly exchange small kisses and touches to let the other person know you’re thinking about them. You can bet that as soon as one of you stands up to get some water or turn down the AC, the other one is already close by asking for a hug.

2) There’s A Lot Of Eye Contact

Every interaction is an opportunity for connection, and that shows how two people communicate with just their eyes.

Eye contact may seem like a trivial thing but it’s crucial for bonding and intimacy. Feeling so drawn to their eyes, whether you’re laughing together or talking about something more serious, shows you’re fully invested in the conversation.

Sharing eye contact is one of the easiest ways to let someone know you trust them fully, so much so that you trust them with the smallest revelations that your eyes might betray. It’s a true sign that there is a higher level of closeness and trust going on between two people.

3) Everyone Else Pales In Comparison

A supermodel could walk in the room and your eyes wouldn’t even flinch. No matter where you go, you only have eyes for them, and you can’t help but feel like you’re the luckiest person alive every time they return your smile.

When you’re really compatible with someone, it’s easy to feel like the whole world becomes a mere backdrop for them. Even when you know that there are other objectively attractive people in the world, you don’t feel like you’re missing out on anything. Your connection is so strong and pure that mere appearances aren’t going to do anything to sully that. Plus, in your eyes, they’re always the best-looking person in the room.

4) Everyday Feels Like An Adventure

There is nowhere else you’d rather be than next to this person. Waking up feels exciting because you know it’s another opportunity to be with them. It doesn’t matter how many times you’ve spent time with them; you always want more.

Even the most boring tasks feel like an adventure when you’re sharing that moment with them. Real romance doesn’t need luxury trips or constant adventures to introduce excitement. When you’re sitting next to a person you’re sharing insane chemistry with and doing absolutely nothing, you know in your gut that it’s still the best place to be.

5) Time Flies

It never feels like there’s enough time in the world to spend time together. It’s very easy to get lost in the conversations and completely lose track of time. Before you know it, it’s time to go to bed or say goodbye to each other.

More importantly, you just can’t get enough. It doesn’t matter how many times you’ve hung out this week, it almost feels impossible to get tired of them. Before even saying goodbye, you’re already thinking of ways to spend time together, or planning your next date.

6) You Laugh A Lot

Sometimes the best things are the simplest ones. In your case, things just click. The air is palpably pleasant and it’s easy to experience light-heartedness in your interactions. Even the dumbest jokes are funny because it’s something that you share together.

Other people wouldn’t get it, because here’s the thing: your jokes aren’t actually that funny. It’s just the togetherness between you two that makes everything seem so easy and happy together, to the point that you can’t help but laugh every time something happens.

7) Communication Is Easy and Exciting

You’ve never experienced communication like this with another person. You don’t struggle to find the words, to string together the sentences, because oddly enough, it almost feels like you don’t have to; they already know what you’re trying to say before you even say it.

With this kind of intense chemistry, you can share volumes with the other person in no time at all, making them understand you in ways other people simply can’t, with a fraction of the effort.

8) You Always End Up Alone Together

Sometimes it feels like fate, sometimes it’s just a strange coincidence. But for one reason or another, you and this person almost always end up alone together at the end of the day.

You could say it’s your chemistry, but it might also be something both of you are doing on purpose. You have such a great time together that you can’t help but fall into your own little bubble of two, leaving you two isolated until everyone else has left the building.

9) You Have Your Own Language

You and this other person have never found it hard to say anything to each other, to the point that you developed your own two-person language. You have your own words and phrases that mean certain things; things that other people just wouldn’t get.

And it’s not like either of you two planned any of this out; it just happened naturally, simply because you’re both so in sync with one another.

10) There Are Butterflies Everywhere

You can’t help but feel it everywhere you go with this person. The feeling of having butterflies in your stomach follows you wherever you go, as long as you’re with them.

You always feel a little light, a little happy, even when you have absolutely no reason to be, and you can’t stop feeling that way. This is why you’re always one stupid joke away from bursting out laughing, or one call of your name away from a quick smile.

11) Even Silences Are Pleasant

But it’s not always about communication; even the happiest couples in the world don’t spend all day talking with each other. There are also the silences, the lulls between the conversations, and you can’t help but enjoy those as well.

With someone with whom you have intense chemistry, even the silences are pleasant. Just simply being around them, enjoying the world while in each other’s presence; these are quiet moments you love having, and you never get tired of them.

12) Undivided Attention

Two people who share intense chemistry give each other a level of undivided attention you just can’t find anywhere else. It’s not about obsessively staring into each other’s eyes; it’s about paying attention to each other even without looking at each other.

You can drown out the entire rest of the world when you’re with this person, as if everything else is just background noise, because you’re so naturally focused on just being there with them, being present with them.

13) You Share The Same Values

When you’re younger, you may say that your values don’t really matter, that you could date someone who has different life values and beliefs as you. But as you age, you start to realize just how difficult it is to be with someone who doesn’t think about life the same way you do.

Because values aren’t just things that you think about when you’re in philosophy class; they’re the morals and standards by which you believe life should be lived. And when you find someone you have amazing chemistry with, odds are you two have the same values and belief systems.

14) You Like Who You Are When You’re With Them

You never feel like you have to pretend. You never feel like you have to be anyone else other than you, yourself, the person you are when you’re all alone with nobody around. That’s the person you can be when you’re with them, because you’re absolutely, completely, totally comfortable with them.

And the best part? You love who you are when you’re with them. They make you feel amazing about yourself, as you do for them. Your self-confidence and self-esteem are boosted simply by being around them, even if you don’t have a single reason why.

15) Other People Notice It Too

And of course, the biggest sign of intense chemistry between two people? Other people can’t stop pointing it out. Chemistry is incredibly obvious to those outside of it, because it’s almost like seeing a kind of magic between two individuals.

In a way it can be irritating, especially if you’re around it for too long, because it can start to feel isolating and a little rude if two people with intense chemistry don’t make any effort to try to include you in their activities. But if other people keep pointing the chemistry out, then it’s absolutely something you have with another person.

16) You Have A Specific Sense of Humor

When you have intense chemistry with another person, you have a specific type of humor that’s almost impossible to find anywhere else.

You and this person are always naturally attracted to the same sort of jokes, the most common phrases and words, so it’s easy for you to make each other laugh in ways that not many others can.

17) You’re A Team

When you and another person have intense chemistry with each other, you become as much of a team as possible. You’re always on the same side, no matter what, because that’s just the type of people you both are.

You can be playing opposite sides of a board game or fighting for opposing teams in a physical game or sport, but it still feels like you’re on the same team.

To experience intense chemistry with someone, your main focus is to take the time to get to know them, understand and appreciate them. You need to learn what makes them tick and how they think of the world around them.

18) Intense Chemistry Is Not Instalove

Instalove is something we see a lot of in the movies: two people meet each other, and suddenly they’re the best thing that’s ever happened to each other, and they believe it will last forever.

But intense chemistry takes time; it takes an incredible amount of time to feel these types of feelings. It’s not because you don’t like each other; it’s because you both know that a simple “like” is nothing compared to an intense attraction and emotional bond.

19) Intense Chemistry Is Hard To Find

You can find chemistry with someone you have an emotional connection with (or even a physical one), but it’s incredibly hard to find intense chemistry.

It’s a rare thing because it’s incredibly hard to find someone who you know appalls you (intense chemistry is not something that happens on first sight, or even the second or third), but also blows your mind.

20) Intense Chemistry Is Not Controllable

You can have chemistry with someone simply because they happen to be attractive, or because you have a type of physical attraction to them.

But you can’t force intense chemistry, or use it as a tool to control someone into doing what you want.

Intense chemistry happens on its own, and even if the two of you were trying hard to actively develop it, there are just no guarantees.

21) Intense Chemistry Feels Real

When two people have intense chemistry with each other, it feels so real, so authentic, and so true that it’s almost impossible to think that you could be feeling this way about them unless you’re absolutely right for each other.

You know deep down that you are. But the only way you’ll know if you’re right for each other is to take the time to get to know that person.

You need to learn everything they like and dislike, their life goals, hopes and fears, what makes them laugh, what they fear and how they feel about things.

Intense chemistry doesn’t happen by accident or by coincidence; it happens when you take your time and give love the type of attention it deserves.

22) You Feel For Them When They’re Not Around

When you have intense chemistry with another person, you feel like they’re a part of your own personal reality.

You feel like you can go anywhere in the world and be with them, just the two of you.

You don’t need to talk to them every day; it doesn’t even matter if you did or didn’t. All that matters is that the two of you are together at all times. You can walk down a street, you can be at work or school, you can be in a different country but it doesn’t matter.

You feel for them when they’re not around, and you know that even if they are far away or not communicating with you at all, that doesn’t change the way you feel about them in the slightest.

23) You Want The Best For Them

When you have intense chemistry with someone, you want the absolute best for them. This can manifest itself in a few different ways:

When you have intense chemistry with someone, you want the absolute best for them. This can manifest itself in a few different ways:

So when it comes down to it, whether they realize it or not, this is exactly how they feel about you as well.

24) Intense Chemistry Doesn’t Need To Be Explained

Intense chemistry doesn’t need to be explained, because it’s something that you both know, and it can be described on its own.

Intense chemistry is when two people have a strong emotional connection to each other (whether through attraction, respect or friendship), they have this special bond that they can see each other clearly and understand each other so well.

25) Intense Chemistry Knows No Boundaries

Intense chemistry doesn’t need a physical sense of distance, or a geographical sense of geography.

Intense chemistry can happen that quickly, over the course of seconds or minutes, and yet it happens almost instantaneously.

You can have intense chemistry with someone you’ve only just met, and you can have it with someone that many years your junior.

Intense chemistry doesn’t care if it’s happening in a small town, or in the middle of a city. It happens over the course of time, but it still remains as strong as it was when all you had to do was meet.

26) You Want To Be With Them All The Time

When you have intense chemistry with someone, you want to be with them all of the time.

You want to go on little adventures together, you want to spend every moment of the day with them. You want to do everything with them, and you can’t wait for the time that you get to see them again next.

In fact, when you have intense chemistry with someone, there’s nothing you don’t know about each other after a short period of time together.

27) Intense Chemistry Changes Everything

Intense chemistry doesn’t always happen the moment you first meet someone.

But when it does happen, it changes everything. When you have intense chemistry with someone, you change in ways that are positive for them, and for yourself.

You become a better person, a better partner and a better friend. Your life appears to get off the ground when you start to fall in love with someone and you suddenly feel like you belong, like you’re exactly where you’re supposed to be.

When two people have intense chemistry, they change everything for the other person, as well as themselves.

28) Intense Chemistry Makes You Feel Complete

When you have intense chemistry with someone, you feel like you’re complete.

You know that they can make your life better, and even your life is able to sustain itself without them.

But when you have intense chemistry with someone, it doesn’t matter what happens, or where you are or what time of day it is-you feel like you’re exactly where you need to be.

You just need to be near that person.

29) Intense Chemistry Makes You Feel Alive

When you have intense chemistry with someone, you feel like you’re alive and that’s all that matters.

You feel excited, happy and like your life is really moving forward in ways that it never has before.

You feel like a different person when someone has made you feel this way.

30) Intense Chemistry Makes You Feel More Alive Than You’ve Ever Felt In Your Life

Intense chemistry makes you feel like you’re more alive than you’ve ever felt in your life.

You feel so alive that it makes you think that maybe you’re not as alive as you actually are.

When you have intense chemistry with someone, it makes you want to be alive more than anything.

The thing is, when you feel this way, and when you feel so alive that it almost hurts…this feeling is never going away. This feeling lasts forever. You will never be able to make this feeling go away, because there’s nothing in the world that can compare with it.

31) Intense Chemistry Makes You Want To Be More

Intense chemistry makes you want to be more than you are.

You want to be the best in everything that you do, and you want to make sure that they’re proud of you. You want to make them as happy as they can possibly be. You want your life with them, and no one else. You never thought that it was possible but at this point…you don’t care what anyone else thinks anyway.
