Answer:
This is really important. If you want to know if the girl you like likes you, she should be doing some moves such as: playing with her hair when she's talking to you, or looking at you with the edges of her eyes, and when you look at her she looks away, or when she goes somewhere just to hangout with you or to see you because she misses hanging out with you, and by the way, its hard to change by hanging out with her and asking her out. Well, if you didn't know by the actions she does, it worked when I knew her actions. Good luck!
