Flirting is a part of all relationships. When you have chemistry with someone, you tend to tone it down to a level where the two of you know you are flirting, but not the people around you. You flirt on texts, but you make sure to never cross a line. The hugs you share are longer than the hugs you would give others. You hug them tighter, squeeze their hands, rub their back, or give a kiss on their cheek. It all feels incredibly intense!

5. Always Smiling

You know you have chemistry with someone when you are always smiling – whether they are around you or not. When you are with them, they find reasons to make you smile, even when you don’t want to. You smile as you think about them when they are not around. Even if they are on a different continent, they are able to make you smile. If this is the smile phenomenon, they are ‘the one’ you have been looking for.

6. Noticing Small Things/Changes

Small details are necessary for a beautiful big picture. When you share a special connection with someone, you start noticing things that others fail to notice. From a new hairstyle, new clothing, their favorite things, likes, dislikes, nervous tics to how to calm them down and cheer them up, you notice everything and make an effort to acknowledge them. You make sure to pay close attention to any story/incident they narrate, and you remember them down to a T.

7. Losing Track Of Time

The phrase ‘time flies when you are having fun’ is an embodying characteristic of what happens when you are with this person. Time seems to literally run away, leaving the two of you behind. You share enough common interests that you can talk about anything and everything. There are so many things you want to tell each other.

Nicholette Jeanne, a blogger, shares how she met her lover online before meeting him in reality, and after bonding instantly, they exchanged numbers and got to know each other better. She recounts how they bonded and says, “Being two of the most stuck-up and presumptuous people online, we quickly bonded over prolonged discussions on religion, philosophy, and a lot of pop culture references in between (i).”

8. Tension

Not the stress-inducing type of tension, but a physical tension always seems to exist between you two. When you are attracted to someone, sexual attraction is also a part of the mix. The flirting and teasing consists of sexual innuendos, and you just can’t keep your hands to yourself.

9. Getting Closer To Each Other

When both of you are always trying to get close to each other in a crowded place, ignoring the world and getting lost in yourselves, it’s a sign that you have chemistry. When you find yourself wanting to spend more and more time together and desiring more and more affection and emotional intimacy when you are together, the chemistry is there.

Wherever and whenever you are with each other and doing whatever, it feels as if it’s just the two of you who are most important, and you are the only two people in the world. In a world where cell phones are an addiction, if a person makes you want to keep it aside, that’s your ‘The One’ you have been looking for.

11. Pheromones

Pheromones are chemicals that affect or arouse you when you are attracted to someone. They produce a sweet-smelling body odor that is attractive to the opposite sex (1). Meaning, if you both are attracted to the way you smell, you have chemistry.
