How do you deal with fickleness?

Either she's too shy or she simply considers you a good friend,nothing more. You too don't seem to be too sure about your feelings for her.It could just be an infatuation which fades with time.Lie low for a while,give time to both her and yourself and think twice as to what shape you want this relationship to take.If she's interested in you,she'll come to you,once you withdraw.If not,then its best to continue just being friends.
