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. If she looks back at you and smiles, that's an invitation for you to go introduce yourself.
On a positive note, this means that they are quite shy and awkward about their feelings. Hence, they get shy and look away quickly if you happen to look back at them. This further means, they have taken an interest in you.
Using eye contact to gauge interest
If you lock eyes with a girl and she immediately looks down and away, that's a sign of embarrassment. She's probably interested, but just feels shy.
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.
Individuals usually look away when they are thinking, hesitating, or talking in a non-fluent way. This behavior likely serves two purposes, the first of which is to shield themselves psychologically from the embarrassment of being judged for not proceeding.
However, if a woman does not hold eye contact, or looks away and does not look back, you can assume she is probably not interested. They say that the eyes are the window into the soul. You can tell a lot about how a woman feels about you through her eyes. Just remember to be subtle and don't stare.
There are so many reasons why he is avoiding eye contact with you. It could be because he is shy, doesn't know that you want to make eye contact, or because he is hiding something from you. In any case, you have a role to play in making sure that he is comfortable enough around you.
Watch for clues that she is trying to avoid you.
If she avoids or finds excuses to get out of time that you would otherwise share together, she probably doesn't like you. If she was thinking about how she liked you she would probably be making excuses to be around you more, not the other way around.
She avoids you
She might pay some attention to get to know you better. However, as you communicated, the girl realized that she wasn't interested in you. If a girl ignores a guy, not answering, not responding, without getting in touch, then, most likely, she just wants to stop communicating.
Things like face touching, playing with her hair, looking down, and fumbling with her hands are all signs that she's nervous. Whether she's talking too much or not at all, do your best to put her mind at ease by making her feel comfortable around you.
5. She smiles – and looks away. No, it's not that she is being coy; it's that she is not sure how to act on her attraction to you. You may notice one another from across the room, but not have the best tactic to meet in the middle and cross the unspoken social boundary that keeps you apart.
It means that she's attracted to you but she doesn't want to embarrass herself by making it seem obvious. So she steals a glance in your direction, hoping you don't detect her doing so. This is why she looks away when you catch her looking at you. But now you know how she feels.
Body language studies claim that a person who breaks eye contact with you by looking down is intimidated (i.e., attracted) and a person who breaks eye contact by looking to the side is indifferent (i.e., not attracted).
Can you feel when someone is attracted to you? Yes. When someone feels you are an attractive person, some things come up between you that aren't there otherwise. The clues aren't always obvious, but you can see some of them by paying attention.
Watch for Their Eye Gaze
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.
By ignoring you, she might be trying to let you down easily. She might not even be that much into you. Maybe she just made a comment in passing that she thought you were nice, but someone had just misinterpreted that as her having a crush on you. Whatever the case, it's always important to manage your expectations.
Sometimes she flirts with me, and sometimes she ignores me. Why does she do that? Because it's fun for her, and she doesn't care enough about you to have an honest relationship. She might not relise that flirting, and ignoring are behaviors that carry a strong message, but in the opposite direction.
Stay attentive of her actions.
If she knows and does like you back she will talk to you more, walk near you, sit next to you, make eye contact, twirl her hair, or give you compliments. She may also be secretive about who she likes.
Avoiding eye contact is also common in people with social anxiety as it raises their anxiety levels. Avoidance of eye contact is associated with shame, embarrassment, and self-consciousness, things people with heightened anxiety suffer from.
Psychopathy, PTSD, and alexithymia (sometimes known as “emotional blindness”) are often associated with greater discomfort with eye contact. So are neuroticism, shyness, social anxiety, and autism.
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.
