She let Anakin kiss her and then suddenly broke away, she was concerned for Anakin (and seemed to have no problem jumping onto him and rolling around in grass), and when Anakin confessed to her, she spoke with much vehemence. Then, we all know what happens in Tatooine and then in Geonosis. Though it wasn't spelled out as clearly on the screen as I would have liked, there was enough shown to understand what she was feeling. Oh, if I didn't make myself clear I was only talking about BEFORE the kiss. After the kiss her feelings were apparent. But would you kiss someone you have no interest in? Because I think that's what it felt like for most audience members. There was no scene to suggest she had feelings for him, then all of a sudden they kiss, even though she turns away she still went in for it also.
