Why is the girl I like doing this?

Hmm she either wants to hint to you to hurry up and make a move or that you have missed your chance. If she knows you like her in that way then it is a really bitch thing to do, but am thinking you have been friendzoned, sorry dude hopefully am wrong but in future be a man of action, dont get shy about kissing in public who cares what other people think you only live once so dont stress. Another theory is you weren't clear enough that you were romantically interested in her and she thinks of you as a friend that she care share personal stuff with and didnt think it would hurt your feelings to see her with another dude.
