If a boy has a crush on you, then he'll go out of his way to try to impress you. He'll want you to think that he's brave, exciting, cool, or even wacky. The next time you're around the boy who might have a crush on you, see if he starts trying to say or do something that is calculated to impress you.
Not entirely sexual, unless the guy is a complete pervert and only has a crush on a girl purely because of her physical appearance then most guys will fantasize about just being around their crush and doing things with them like kissing/hugging etc.
If you notice he is making more eye contact with you or you catch a guy staring at you, he is probably attracted to you. He may be enthralled by your good looks and may be fantasizing about kissing you. Perhaps he stares at you and smiles; that could mean he likes you, too.
You Can Feel It
This one is probably a no-brainer; when someone is attracted to you, they want to touch you. Touch releases the bonding hormone oxytocin. So, it is an instinctive way of trying to strengthen your connection. However, not all touches mean the same thing.
Another clear sign he likes you is if he is actively trying to hang out with you, or help you, or find out more about you. There are also indicators like eye contact or compliments, and showing that he's interested in your physical appearance, or who you are as a person.
Contrary to popular belief, guys always seek attention from girls—especially the ones they like. Guys try to hide the fact that they like the girl by teasing her. In a way, it's still flirting.
They will lean toward you and remember all the tiny details about your appearance and about the meeting itself. They will make a humongous effort to keep the conversation going. You will get a gut feeling someone is attracted to you when they do all these things.
They Smile A Lot
If someone often smiles when they are in your presence, that's also a potential indicator that they like being around you. But the kind of smile also matters. If a person smiles at you often with a broad, ear-to-ear grin, they're making it known that they're into you.
If he wants to know more about you, it's likely that he's been thinking about you. He may also ask you questions or get your opinion about something to see what you think, which is another major clue that you're often on his mind. If he says, “I was wondering what you like to do for fun.
A flirty guy will talk about his love life, best date, romantic nights, and related topics. The reason is to allow you to have a glimpse into his romantic side. If he is friendly: A friendly guy will talk about his interests, hobbies, work, etc. They will rarely mention anything related to their love life.
Here are the typical signs someone is attracted to you:
They tilt their head as you speak (a sign of engagement). They smile at you. They make eye contact with you. They reach out and touch your arm, hand, back, or leg.
This feeling is what we usually call chemistry between people, or "the spark"—a twinkle in the eye, a skipped heartbeat, or flushed cheeks that indicate two people are truly connecting.
Your cheeks flush, palms sweat, and heart races
“This can lead to having a physical sensation of craving and the desire to focus your attention on that specific person,” she says.
1) His eye contact is strong
He keeps glancing over and when he catches your eye he holds his gaze for a long time. Maybe it's the guy who checks you out from across the bar or your colleague who always makes eye contact when you pass by him in the office. Notice how he looks at you.
If someone has a crush on you, there's a fairly good chance they'll be glancing at you more often than others. They might stare at you when they think you aren't noticing and might even look away if you catch them. Such sneaking glances at you may indicate they like you as well.
Things You Should Know
Look for signs in his body language like eye contact and leaning in towards you while talking. He'll also initiate more physical touch between you. Study his behavior, including the time between text responses and how jealous he seems when other guys are mentioned.
He wants to let you know what he thinks of you without saying too much. Often, people who like you want you to know it, even if they're scared to say the words, “I like you.” Instead, he might tell you that you have a great laugh, or that he admires your confidence.
He needs some time to be sure of his feelings. Sometimes, guys withdraw from a situation and act uninvolved to be able to see it from a different perspective. By keeping a distance from you, he is trying to see the relationship differently and understand if he really wants to keep this going.
