He'll be looking at you a lot or he will be constantly wanting to be near you. If you want to hangout or if you're just standing somewhere. He might tease you a little bit to flirt. Hope this helps. <3

Try flirting with him and if he likes it he probably likes you
You should tell the guy who likes you that you don't like him, but not until you ask the guy who you like if he likes you.
The most accurate way to find out is to ask him.
Talk to him, find out what he likes/dislikes - he may not "not like" you, he may simply not know you. Get to know him, and if you find that he likes you too - great - if he doesn't don't let him hurt you and find someone who does like you. Let me improve what this person wrote its "impossible" if the guy doesn't like you he's not going to change he's mind!
you ask him if he likes you
