Treating a girl well, flirting with her, and being honest about your feelings are all great ways to give her the confidence to tell you that she likes you. Once you are able to make a girl feel comfortable, she'll be more likely to be honest about her feelings for you.
How can you tell if someone likes you but doesn't show it?
Notice if they look for attention.
Someone who likes you may do something to have you notice them. Watch if they talk louder when you're nearby, or starts laughing with their friends when you're around. They may not talk to you on a social website, but they'll "like" a bunch of things you do online.
How do you know if a girl is playing with your feelings?
She is never the one to initiate plans or conversations and never really seems interested in talking to you or investing in the relationship. She makes you feel ignored, sidelined and taken for granted. When a girl is playing you, she will manipulate you and will not let you know what she truly feels for you.
If she looks away really fast, or smiles, or blushes, she's into you. If she casually looks away and doesn't engage anymore, she's probably not into you. If she's talking to you and laughing/smiling a lot, she's flirting. If she's playing with her hair, she's flirting.
One of the signs he secretly loves you, is he often tries to impress you. He might try hard not to make his feelings obvious, he might not want to say he actually loves you — but then he'll never miss out on an opportunity to impress you. Advit would always do it.
People tend to naturally lean toward people they like in conversation, according to Battle. If the guy you like tends to lean his face in closer to yours while he's talking to you or listening to you talk, that's a good sign that he might be into you.
You can often see such differences between introverts and extroverts too. People who like you lean towards you and engage in conversation. Meanwhile, not looking you in the eyes, leaning away from you, and crossing their arms or legs or both are signs that they don't like you.
How to deal when a friend has an unrequited crush on you
Don't lead them on. It's nice when someone has a crush on you. ...
Be kind, but clear. It's necessary to let your pal know you don't have feelings for them, but it's just as important to be sensitive about how you do it. ...
When someone is interested in what you have to say, they'll move closer and lean in. This is another subconscious action that tells the onlooker (you) that the person likes you. They may lower their head, lean in while you talk, and even move their body closer to yours – all without even realizing they are doing it.
If they blush around you, laugh uncontrollably for almost no reason, can't look you in the eye, or fidgets a lot, then you have your answer. These are all tell-tale signs of someone who is crushing. See if they mirror your behavior. A common sign of attraction can be shown through imitation.
