Any meaning beyond friendship?

i went to this bar to meet some friends and saw this girl I used to like...said hello from where I was sitting and kept on with my friends, she stood up from her seat and came to hug me and say hello...then I saw her couple of times looking at me but I ignored her all night...she then came once and touched me in the chest and left...i spoke to her few times but mostly ignored her, when I was leaving I said bye from far and she gave me this face like why aren't you saying good bye properly, I just said bye and left...do you women see any clues of something beyond friendship or is this normal behavior with friends?

i see her as a woman who likes me but's not sure if she wants to be with me, any suggestions for this? I'm just being indifferent and paying no attention to her when I see her..
Any meaning beyond friendship?
