you really should put more details in. \n\nbut just from the top of my head, you can tell if a girl likes you if she's sending you the right signals. does she laugh at your jokes, even the corny ones? does she find excuses to touch you, like brushing lint off your sleeve? does she enjoy spending alone time with you? if yes, then she probably does. if not, then she might just see you as a friend.\n\ndon't be presumptious though. to get a straight answer, either talk to her, and find out if she has feelings for you; or you could do something drastic like kiss her on the lips, and see how she reacts. play it cool though. don't freak her out in case she DOESN'T like you.
