depends..girls like attention and flirting. If she does not like you, she would probably tell you that she was involved with someone right away just to get away. If she responds to your cues, then there is no doubt that she is interested. Be careful though, too much too soon can destroy everything. So take baby steps and do not act desperate..disappear for a day or two..she will come running simply because she could not handle a sudden shift in attention.
