Nice question! You know I am a girl and I can help you (btw I am shy to my crush)
. If she likes you, she will either hold it for a long time or pull away immediately. Either of these could mean that she likes you. If she pulls away quickly, it means she is nervous but she still likes you - which means that you should probably make the first move. If she holds the stare, then she is confident and she may make the first move. If you happen to glance at the girl and you see her staring back at you, then this means that she likes you, although she may quickly dart her head in a different direction. Look for her eyes to light up when she sees you or hears your name.
Also
If you see most of her friends glancing back at you and smiling or giggling, this means that she is telling her friends about you. If her friends are loud and immature, you'll hear "(your name), (her name) likes you!" Her friends might be making it up, however, just to tease her. When she is having a conversation with her friends, and you come over, she might stop talking all of a sudden. This likely means you were the subject of the recently ended conversation. If she likes you and she told her friends about you, they might come up to you and start a random conversation about things such as: Who would you rather date, Who do you like better, Who is the hottest, etc. If they name a list of about 3 people and her name is in the list, she probably told her friends about you and they're trying to search for clues to see how you feel about her.
AND SMILE!! Do a natural smile - don't freak her out. If she smiles politely, or frowns and looks away, say goodbye to her. She is obviously freaked out by you. If she returns a soft or big smile and continues to look at you, then she is interested. If she smiles then darts over to the crowd of her friends and hides in the group then she may be nervous and curious if you know that she likes you.
Fianly
The signs are the nodding, the hair messing, the staring, the certain talking, and the body language.
Guys find it hard to get the hint that a girl likes them because they may not know how to read body language.
body language
If you look at her body language it will tell you if you dont know how just ask her out.
She looks at you in a special way and likes to touch you.
Body language is the main things which tell most of the things. If she shows signs of submissiveness and closeness she might still be into you. If she contacts you more often she might still be into you.
She smiles at you when she looks at you, and she also seems to want to see you again beyond what she HAS to do.
It is generally recommended to approach the topic indirectly and gauge her interest through conversation and body language before directly asking if she likes you.
if they are picking on you that means he or she likes you or if they tell you
It's up to the girl.
Coming from a girl, she may be shy around you and keep smiling when she sees you. Or if shes a chatty girl then she make obvious herself. read her body language.
Watch for signs such as increased attention, compliments, and efforts to spend time together. Direct communication or asking the guy about his feelings can also provide clarity on who he likes more. Pay attention to body language and how he interacts with each girl to gauge his level of interest.
