The main thing you can do is try to converse with her, that's the only way you can figure it out. There's a few key things about how girls usually act when they're into someone, or atleast thinking about them in a way more as friends, and these things are not dead giveaways that means she likes you, could mean completely different things as well. 1) she will tend to act small or insignificant when compared/ talking to you. This is just a natural thing girls do because they want masculinity. Basically just sizing herself down in her mind, she'll try to not talk about herself as much. This is a deadly trap, it could go either way, to counter it you want to talk to her about her. What she likes, does, thinks etc. 2) touching. This is a peculiar one, it shows comfort if she touches you lightly, or she's okay with you doing the same, and I'm not talking about hugs or anything, like when your talking and you just lightly touch her arm or something, or if she does the same, it's an indicator of interest, not of liking, but interest. She may brush by you purposely, lightly touching you with her body. Something like that 3) eyes. This one is alittle more intimate, but look for what her eyes do when your talking to her face to face. If she's darting around the room, she might be either stressed or looking for a way out of the conversation. If she's looking into your eyes she's interested in the conversation. If she looks from your eyes to your lips repeatedly, she may be wishing for a kiss. (If your talking to her face to face and you notice the eye-lips thing try touching her fore arm or something gently, if she keeps doing eye-lips, she most likely is thinking about kissing you. ) 4) reactions. Laughter is a big one here. If she laughs at what you say a lot, even if it isn't funny, could just be ironic or something, she's giving you a sign, however this could be a sign of friendship, or liking, not easy to tell which. You can also notice how comfortable she is talking to you, she will tend to be less comfortable if she's into to you. Now I'm not talking like uncomfortable in a like "get away from me" manner, but just tid bit more high strung than usual, like more careful choices of words or something. If she's careless about what she says she also doesn't care if you are interested in her or not. Girls are weird man, and as guys, seeing the signs is hard, because they could mean a bunch of different things. But you have to make the effort to talk to her, and don't be nervous when you do, just strike a conversation with her, compliment her but don't be too assertive or vague with the compliment, she doesn't want to be treated like a piece of meat, don't say she's pretty, look her straight in the eyes and tell her that she has beautiful eyes, you don't have to go more indepth with complimenting either, just leave it at that.
