It's a way of silently signaling to you his interest. And he is hoping that you notice him back and look his way. After all, if you look his way, then it might give him a chance to smile at you. If you respond positively to that smile, then he'll be on his way to approach you!
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.
In this type of eye-contact, the other person stares at you even after you look back at them, and then looks away after wee more seconds. The delay in looking away can mean that they are trying to be a tease, after leaving a lingering glance on you. This short move promises attraction.
It means that she likes you but is too shy to show it. If a girl really likes you or the way you look, looking into her eyes will give that away. If she's confident she look back at you and smile. But if she's shy she'll look down or away to hide her feelings.
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.
He's asserting dominance.
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.
If she's giving you a friendly look or watching you do something fun, staring might be a sign that she wants to be friends. If she's gazing deep into your eyes while smiling and/or initiating touch, she may have a crush on you. If she's glaring at you, she could be mad at you or someone else in her life.
If a girl avoids eye contact with you, it can indicate that she's interested in you or not. Also, it might mean that she avoids eye contact generally with people or doesn't want a conversation with you. Regardless of the reason, checking her body language and talking to her might tell you why she avoids eye contact.
He likes you
When a guy avoids establishing eye contact, it could be because he likes you or has a crush on you. He may think that by avoiding eye contact, he can mask his feelings and make sure that you don't suspect that he feels attracted to you.
He is probably attracted to you. I would think that shyness or maybe he's already attached, so doesn't speak to you. The fact that he sees you also looking at him (i.e. seemingly taking an interest) is also most likely attractive. If you don't like it, then make a point of not looking at him at all.
Your potential love interest stares at you while you are in the middle of something or talking to someone. He or she may look away when you catch them staring at you, or might hold eye contact as if they're trying to memorize your features.
Look away.
The easier thing to do, especially if you have a really quick reaction time. Let him make sense of the situation the way he wants to. If he tells people about how he caught you staring at him, he'll only look like someone with a huge ego. He has no choice but not to mind what just happened...
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.
A man likely stares at you because he has feelings for you. You can't do anything except stare back into his eyes. He will pick up on your interest, and soon it will be a game of who will stare at the other longer. Staring is an opportunity for you to develop a bond with him.
If she's into you, you'll catch her staring at you when she assumes you don't notice. If you catch her looking at you and she quickly glances the other way, she might be into you but shy about it. The fact is, if she's attracted to you she'll keep looking at you consciously or subconsciously.
Eye contact is a subtle but strong sign. If she holds eye contact with you, that could be a sign she's interested. Let's say you're in a social setting and a woman across the room looks at you. If she looks at you and then instantly turns away, it may be because she is shy or doesn't want to get caught looking at you.
She looks at you
If she's interested and forward, she'll be looking at you and will maintain eye contact when you lock eyes. She may smile or she may scan your face and give you a double-take. This is a pretty obvious sign that she likes you and she isn't afraid to show it, either.
When done without blinking, contracted pupils and an immobile face, this can indicate domination, aggression and use of power. In such circumstances a staring competition can ensue, with the first person to look away admitting defeat. Prolonged eye contact can be disconcerting.
How to know if a girl likes you but is hiding it? She may not request for or say it explicitly, but one of the signs that a girl loves you secretly is that she always wants to be with you. A girl interested in you will look for opportunities to be around you or initiate conversations or activities with 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).
If someone smiles a lot when they look at you and connects eye contact with smiling, it is usually because they find you attractive. They might also make fun of you and tease you, or try to make you laugh. If someone's into you, you make them nervous. Their heart will beat rapidly from being around you.
