When I was younger I did the complete opposite.I tried everyway possible to get them to notice and be with me but it never worked. I changed my mindset and it's done wonders for me. I'm still not picking up girls left and right but I feel I understand how this shit works now. I'm not so quick to just hang out or make her the center of my universe. Makes me feel so much more in control and confident to. Live your life and love what you do and she'll be lucky to come along for the ride. That's the attitude you got to have.
