How do you find out if a girl likes you?

the best thing to do is tell her that you like her, ask her out, do something! cause she may like you back but could be too scared to do anything about it! just think how awful it would be if u two liked eachother but never said anything. ask her how she feels and then u will know! its better to have tried and failed than to live on not knowing!! i wish u the best of luck, and remember, dont ever change who u are for anyone!!
