I'm assuming doing the Become Irresistibly Attractive and Develop Aura of Sexiness should naturally make you feel like she wants you, regardless if she does or not? I remember when I first started affirmations I had this high where I literally thought EVERY girl that came near me wanted to be with me. So there was a point where I would say hey or make some random comment like they did and practically every single time the girl responded well. But yeah if you feel confident just look her in the eyes and say Hey, that's all it really takes 
Obviously, if she was trying to get your attention/wanted you she'll lit up instantly (or sometimes speechless) when you say Hey.
