Its hard to say whether its possible or not but I'll tell you your best chances are to find other nice (or bad

) girls to hang out with, although it seems counter intuitive, if you forget about her your chances are higher. If by next time you guys physically see each other again, you can display some strong alpha changes, she might pick up on them and rethink the way she is treating you.
Frame yourself in this context:
If you were in a tribe thousands of years ago and a neighboring tribe comes to take your women, your food and your xbox360, would you have the INSTINCT (notice I didn't say the physical ability) to grab a stick and beat them to the ground? Apply this to your behavior in modern society, you don't go around beating people with a stick UNLESS they truly and purposely fuck with you, does that make sense?
If you have a beautiful woman next to you, do you stand your ground? or do you let anything else claim her in hopes that she loves you more? Its not a matter of being possessive or controlling, that is uneducated and socially unaware behavior. By stating to the world what you want from life, people think twice before stepping out from under your wing, knowingly losing your friendship is no longer an attractive choice, the problem is she currently doesn't know about this consequence.
Hope that made sense, my favorite thing about the alpha frame is that you must only apply tension in small doses to hold the frame together in times of stress, most of the other time things go very smoothly because people see you as bringing value and protection to their lives. Thats important, an Alpha isnt a Predator he is a Protector of the people and things he loves.
I read something funny the other day about being an Alpha Buddha, thats fucking genius lol!
