A guy might be so captivated by your appearance or demeanor that he forgets to smile or simply doesn't know how to react. The lack of a smile might not be a sign of disinterest; rather, it could indicate that he's feeling a strong connection and doesn't want to look away.
He's Staring at You
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 a man is staring at you he is likely sending a message that he is interested in you. This one is a bit tricky. He doesn't have to stare at you the whole time, but if he does it more than once, then you can be sure that he's very interested.
It means that neither of you are a subtle and sly at watching the other as you think you are. He could be looking at you because he is interested in you. It is just as likely that he is looking at you because he has noticed you watching him and he is trying to figure out why you are watching him.
I suspect that it is that he (or she) is interested in you as well, and they see you looking at them simply because they are watching you. It could be that they just can't keep their eyes off of you. It very much sounds like they have strong feelings for you as well. It may feel awkward, but talk to them.
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.
Someone who is super interested in you will want to talk to you all the time. If you and your crush have lengthy conversations often, or even just send a few short texts throughout the day, it's likely that they have strong feelings for you. This could also be a sign that your crush thinks of you as a very good friend.
Like touch, eye contact triggers the release of oxytocin. 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.
He is looking at your lips
If his gaze keeps slipping down to your lips while he's talking to you, it's a sign that he is admiring you, fantasising about you and might even want to start a stable, long-term relationship with you," says Madan.
Unfortunately, aggressive guys use staring as a type of power play. If he's looking at you intensely without smiling and even looks angry or stern, he could be trying to assert his dominance. In this case, his stare will feel like a challenge—in his mind, the weaker one won't be able to keep eye contact.
Staring can seem aggressive and predatory, and make your crush feel scared or uncomfortable in your presence. Try to casually glance over at your crush from time to time, or admire him or her using your peripheral vision.
“Holding someone's gaze tells them, 'I'm interested in you, and I'm worthy of you,'” says Barrett. “It also makes a person feel 'seen. ' As the saying goes, the eyes are the windows to the soul, and part of attraction is feeling that the other person sees the real you.”
Aside from making an effort to spend more time with you, someone who finds you attractive will most likely try to reach out and connect with you as well. If they're a bit shy and not much of a talker, they might do this by simply following you on social media and engaging with your posts from time to time.
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.
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.
Look at them.
Make direct eye-contact when you walk up to them and maintain it as you talk. Show them that you're interested in what they have to say by keeping your attention on them. Avoid glancing away and staring off at something else, which might make them think you're bored, distracted, or feeling defensive.
Typically, a guy would stare at you if he has any sort of romantic interest in you. Logically, we do not engage in long stares when there are platonic feelings involved. It usually hints at a feeling of longing. Maybe they yearn to connect with you and talk to you about how they feel and are afraid to do so.
Full body gazes begin with an extended gaze, are followed up by a longer look over the mouth, down the body and back up to the eyes. This type of eye contact is brazen and highly sensual. The person may respond with a similar gaze or appear to blush.
Use the five-second rule. While maintaining eye contact can feel good, too much of a good thing can feel intense or awkward. Five seconds, or about the time it takes to say 12 words or a single sentence, feels suitable to most people. After that, look away for a moment and then back again.
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).
Neuroscience Behind Attraction
The first spark of attraction happens in the ventral tegmental area of the brain which produces the “feel good” neurotransmitter known as dopamine. These chemicals may cause one to be giddy, euphoric, and even to experience suppressed hunger and sleep cues.
