Anyway, seems like she is into you. First thing is, something went wrong before, analyze it and try not to repeat the same mistake.
Don't go confessing just yet, girls are complicated. Once she knows you want her, she expect you to chase her. Let her chase you once in a while. The more she put the effort of wanting you, the more she will appreciate you. On the contrary, the more you tell her your feelings, the less she need to put in effort, thus, the less she would appreciate you comparing to you appreciating her.
Make any sense?
