You’re sitting across from them at a coffee shop and suddenly you realize the air feels different. It’s that weird, prickly sensation in the back of your neck. Are they staring? Or are you just overthinking the way they laughed at that joke which, honestly, wasn't even that funny? Figuring out if there is a crush on you is basically the world’s oldest guessing game, but it's one that scientists and psychologists have actually spent a lot of time trying to solve.
Attraction is messy. It’s not a checklist. People aren't robots, so they don't always follow a script.
The Body Language Myths People Actually Believe
Most people think a crush is obvious. They look for the "big" signs, like someone tripping over their words or buying flowers. Real life is quieter. Research from the University of Kansas, specifically a study led by Professor Jeffrey Hall, identified five distinct styles of flirting: physical, traditional, polite, sincere, and playful. If you're waiting for a "physical" flirter to act like a "polite" one, you'll miss the signals entirely.
It’s about the baseline.
If someone is naturally loud and bubbly with everyone but turns quiet and focused only when talking to you, that’s a massive indicator. It is the deviation from their normal behavior that matters most.
Think about "pupillary dilation." It’s an involuntary physiological response. When we look at someone we find attractive, our nervous system kicks into gear and our pupils expand to let in more light. You can't fake that. You also can't fake the "prologic" lean. Dr. Jack Schafer, a former FBI behavioral analyst, often discusses how people lean toward things they like and distance themselves from things they don't. If their torso is angled toward you even in a crowded, noisy room, their brain is prioritizing you over the environment.
The Digital Footprint of a Secret Crush
We live on our phones. This changed everything.
Back in the day, you had to wait for a phone call or a note passed in class. Now, the signs of a crush on you are buried in your notifications. It’s the "double tap" on a photo you posted three years ago at 2:00 AM. It’s the speed of the reply.

"Breadcrumbing" is a term people use for a negative behavior—sending tiny bits of attention just to keep someone interested—but in the early stages of a genuine crush, it looks like "active engagement." Does this person consistently view your Instagram stories within the first ten minutes? Do they send you memes that actually relate to a conversation you had four days ago? This shows "cognitive salience." You are occupying space in their working memory even when you aren't physically present.
How to Spot a Crush on You Without Asking
You don't want to make it weird. Nobody wants to ask "Do you like me?" and get hit with a "No, I was just being nice." That's the ultimate social nightmare.
Instead, look for the Protective Reflex.
Evolutionary psychology suggests that when we like someone, we subconsciously try to shield them or make their life easier. This might be as simple as them noticing you're low on water and getting you a refill without asking. It could be them remembering your specific coffee order or a random detail about your childhood pet.
- Mirroring: This is a classic. If you cross your legs, they cross theirs. If you take a sip of your drink, they do the same. This is the brain’s way of saying "I am like you, and I want us to be in sync."
- The Eyebrow Flash: A fraction-of-a-second lift of the eyebrows when they first see you. It’s a universal sign of recognition and positive interest.
- Removal of Barriers: Watch out for "objects" between you. If you’re at a table and they move their phone, their glass, or a menu out of the way so there is a clear line of sight, they are subconsciously removing barriers to intimacy.
It's kinda wild how much our bodies betray us. You might think you're playing it cool, but your feet are pointing directly at the person you want to talk to.
The Science of "Limerence"
In 1979, psychologist Dorothy Tennov coined the term "limerence." It’s that obsessive, all-consuming stage of a crush. It’s not quite love, and it’s more than just a "like." When someone has a crush on you that has reached the level of limerence, they experience "intrusive thinking."
They might mention you in conversations with friends constantly. They might remember tiny details you forgot you even mentioned. This happens because their brain is flooded with dopamine and norepinephrine. It’s a literal chemical high. However, it's worth noting that limerence can be blind. A person in this state often ignores "red flags" because they are hyper-focused on the "glimmer"—the small signs of perceived reciprocation.

The Difference Between "Nice" and "Interested"
This is the part where most people get tripped up.
Some people are just naturally charismatic. They make eye contact. They ask questions. They listen. How do you tell the difference between a "People Person" and someone who actually has a crush on you?
Look for the "Special Treatment."
If they are amazing to everyone, their kindness toward you is just their baseline. If they are generally sarcastic and standoffish but soft and attentive with you, that’s a signal. If they go out of their way to do things for you that offer no benefit to them, that’s interest.
Social Psychologist Eli Finkel, who has done extensive work on relationships at Northwestern University, points out that "invested" people show a willingness to sacrifice their own convenience. If they’re willing to drive forty minutes out of their way just to drop off a book you mentioned you wanted to read, they aren't just being a "nice person." They are building a bridge.
Anxiety as a Green Flag
Usually, we think of anxiety as a bad thing. In the world of attraction, it can be a huge tell.
If someone is super confident with everyone else but gets a little bit "clumsy" or "awkward" around you, it’s because the stakes are higher. They care about your opinion. Their heart rate is likely elevated (tachycardia), which can lead to fidgeting, touching their neck, or adjusting their clothing repeatedly. These are "pacifying behaviors" designed to calm the nervous system down.

Moving Beyond the Guessing Game
So, what do you do if you’re 90% sure someone has a crush on you?
You have to test the waters. You don't need a grand confession.
Start with "Physical Proximity." Move a little bit closer into their personal space—not in a creepy way, just a subtle shift. If they lean in or stay put, that's a "yes" from their nervous system. If they subtly shift away, they’re likely just being friendly.
Another trick is the "Small Favor." Ask them for something tiny, like holding your jacket for a second or giving you a recommendation for a movie. If they jump at the chance and then follow up later to ask if you liked the movie, they are looking for "re-engagement." They want the conversation to keep going.
Attraction isn't a mystery that needs to be solved with a magnifying glass. It’s a vibe. It’s the way the energy in the room shifts when one person walks in. It’s the silence that feels comfortable instead of awkward.
Actionable Next Steps to Take Today
- Establish a Baseline: Observe how this person interacts with coworkers, friends, or baristas. If their behavior with you is "different" (more intense, more quiet, more helpful), you have your first real clue.
- The "Three-Second" Look: Next time you catch them looking at you, hold the eye contact for an extra second and smile. If they look away quickly and then look back, or if they blush, the interest is likely romantic.
- Check for "Micro-Valuation": Pay attention to whether they remember the small, "unimportant" things you say. If they bring up a niche hobby you mentioned once three weeks ago, they are actively listening with intent.
- Initiate a Low-Stakes Hangout: Instead of a "date," suggest something casual. "I'm going to grab a coffee/check out that bookstore, want to come?" Their level of enthusiasm will tell you everything you need to know.
Real attraction doesn't need to be forced. If the signs are there, the best thing you can do is create an environment where the other person feels safe enough to be more obvious. Be present, be yourself, and stop over-analyzing every single text message emoji. The truth usually reveals itself in the way they look at you when they think you aren't looking back.
