Should I have kissed her? (We were friends.)?

I wouldn't worry about it too much. I dont think kissing he was a bad thing to do... if she didnt want you to kiss her then she would have pulled back right after you put your hands on her hips. give girls a little more credit... we usually know what you are going to do before you even do it. I am sure she will call you back. just give her some time. it sounds like she really likes you. best of luck... i hope all works out well in the end. :)
