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).
When a guy likes you, he makes an effort! He texts, calls, plans dates, picks you up and picks up the check. He doesn't mind working a little harder because he feels you're worth the effort. He makes you feel “comfortable”, and you can be yourself around him.
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 he is flirting with you, he may lean closer towards you while you and he are speaking. He may angle his body towards you, make eye contact, keep his feet faced in your direction, or tilt his head while he talks to you. These body language cues signal one thing: He is very much into you!
You will often witness a spark in their eyes when they are looking at you or having a conversation with you. They will smile at you as if you are art personified. You can tell if someone likes you if you can sense them looking at you even when you are pretending not to notice.
So if you notice that his cheeks are flushed, he smiles anxiously, or he keeps biting his lips or fidgeting around, it's a sign he probably likes you. Now, even if you've had great eye contact and he seems self-assured, make no mistake that he could be on edge when you're around.
If when you're around he consistently points his chest and feet towards you, he's probably interested in getting to know you better. Also, if he tries to interact with you and getting to know you more than he does with other women, he probably likes you.
Men who are interested in you will likely face directly toward you during conversation. Even if you're with a group, he might turn his whole torso to face you. Watch to see if he's trying to “close you off” and keep you to himself.
Try this instead: Make great eye contact while talking to him. It's sexy, smart, and shows you're really listening. Laughing can be a great way to flirt—when things are genuinely funny. But if you're speaking to a man and you laugh at everything he says, you'll confuse him and come off looking a little ditzy—or nuts.
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.
The closer he wants to be to you, the more he probably likes you. This body language is a minute way that guys go for physical contact. People who are just being nice don't want to get closer and closer to another person. Instead, they'll keep a safe distance and might lean away if you try to touch them.
You look forward to seeing them and feel energized, even euphoric, when you spend time together. Depending on the situation, there might even be a chance that the feelings are mutual. When your relationship with your crush doesn't go anywhere, you might feel, well,crushed. And that feeling is far from fantastic.
