There are a few dead giveaways that indicate he's interested. If he holds a hug for a super long time or he “accidentally” brushes your shoulder or touches you, he's probably into you. If he's just being friendly, he may smile and make eye contact, but he won't go out of his way to touch you.
A guy who likes you will always be nice and polite in his approach towards you and he will always look for avenues to spend more time alone with you and get to know more about you- either by going on a date, through constant phone calls or chats- the subtle signs are always there if you pay close attention.
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.
A man who likes you more than just friends will typically pay closer attention to you more than he does to anyone. If you find yourselves in a room full of people, and he still stands closer to you and caters to only you, then he must genuinely like you.
You will often witness a spark in their eyes when they are looking at you or having a conversation with you. They will smile at you as if you are art personified. You can tell if someone likes you if you can sense them looking at you even when you are pretending not to notice.
He'll stand close to you. He might place his hands on you casually, like touching your arm or your shoulder when laughing at a joke. “A guy who holds your hand or puts his arm around you is showing interest. We don't tend to touch people we don't like, so touch can be an indication of attraction.”
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.
If he compliments your eyes, the color of your hair, your laugh, or an admirable aspect of your personality, then he's definitely flirting with you. He may even tease you a bit while flirting with you, like if he says something like, "That's the brightest sweater I have ever seen," but he's still flirting with you.
When he is flirting with you, he may lean closer towards you while you and he are speaking. He may angle his body towards you, make eye contact, keep his feet faced in your direction, or tilt his head while he talks to you. These body language cues signal one thing: He is very much into you!
Some guys tend to have a nature that's naturally charming and always exhibit flirtatious behavior. Just because a guy likes to have a friendly conversation with you or throws a few flirty compliments your way, it doesn't mean he likes you intimately. Observe the little things that will give you a clue on how he feels.
In general, he just seems to be energetically drawn to you in the room—as if his focus, body language, and general energy all just seem to be kind of focused on you. Even when he's off talking to someone else, there still seems to be the vibe that he's paying attention to you.
If a boy really has a crush on you, then he'll be likely to give you all of his attention. He'll turn his body toward you, make eye contact, and won't look around for his other friends or text them during your conversation (unless he uses his phone as a crutch because he's nervous).
You can tell that a shy guy likes you if he gets extremely nervous around you. He may suddenly start behaving awkwardly or clumsily. This kind of nervousness comes from wanting to appear cool and do things right in front of you, but failing miserably at it.
Watch for Their Eye Gaze
When someone is attracted to you, they subconsciously will try engaging in lots of mutual eye contact. They do this to feel closer to you, and because they are interested in you and what you are saying.
Guys with a crush might wonder what you're like—and if you like him. If he's curious to know more about you, he'll generally stare intently at you to indicate his interest. He may also approach and strike up a conversation, asking you thoughtful, open-ended personal questions to get to know you.
Would a guy blush if he didn't like you? Maybe. The reality is that a man could blush around a woman if he is the self-conscious type in general. It may just be that he cares about what people think of him.
Researchers concluded that falling in love is much like the sensation of feeling addicted to drugs with the release of euphoria, including brain chemicals like dopamine, oxytocin, adrenaline, and vasopressin.
Guys tease and make fun of girls they like because they want to be noticed. 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.
The hallmarks of flirting are surprisingly universal. Women often smile, arch their eyebrows and widen their eyes, tuck their chin down and turn slightly to the side, toss their hair, put their hands near their mouth, and laugh. Men, for their part, often arch their back, stretch their chest, and laugh as well.
