OK, lets start over. Ignoring her is not going to help, chasing her will make you look bad.
Lets just step back, take a deep breath, then start all over again with her.
You have to be able to DHV, not getting around it, if you want to game this girl.
#1 - Work on your inner game. Build up your confidence. You are the prize.
#2 - Do your very best to become emotionally unattached to the outcome of your conversations with her.
#3 - Be ALPHA, smile. Dont act needy
get yourself a nice opener, like "Real quick, I need a girls outlook. My friend just got a 3 legged dog, and wants me to name it. I would have named it Skippy because of the way it runs, but its a girl dog. You can't name a girl Skippy, lol. Any ideas?"
Yes its silly, and no its not ment to make her attracted to you, its just ment to get you talking in an indirect approach.
THEN
BE cocky funny.
you - "Hey I like your (whatever)."
her - thanks
you - did you buy it new?
her -
give her a hard time dude. Treat her like a bratty little sister, untill you get 3 IOI's, then PULL THE TRIGGER, give her an IOI back, ask her out, get her number, whatever, just do SOMETHING after 3 IOI's
