You dont contact her. You work on your game. One day maybe a month or two down the road you just happen to come across her number & you call.
She'll do the typical "What have you been up to?" question.
Be vague, but hint that youve been busy, and busy w/ friends, family and girls. DHV. But keep in mind not to sound like your bragging or trying hard.
Inquire what shes been up to, if she hasnt already told you. If she mentions how shes not w/ the bf anymore or theyre fighting. Bait her for a meeting.
you
"Whatre you doing this Fri?"
girl
"nothing."
you
"Oh wait...Ive got plans. What about Sat morning or in the eary afternoon?"
girl
"Nothing."
you
"OK Im free then. Lets have brunch. We can play catch up."
Hope you get the idea.
You're a busy guy w/ lots of people to interact w/. You're just being kind enough to ALLOW her into YOUR life. YOUR reality.
JUSTINcredible!
"The instant she looks at my direction, she done."
