To quote David X
You cant expect her to have her life as sorted as you. She's probably dealing with a whole load of issues that arent even you related.
Do you want to be the guy that worries because a woman didnt call back or do you want to be the guy that keeps going forward regardless.
As soon as you start coming from a place of abundance then all your problems dissapear. Why worry about an outcome if you know you'll be happy regardless.
Use what ever dissapointment you get a tool to spur you on to the next lesson. Never give up. Never stop. Your on a jouney in life and she can either be at your side while your doing it or she can get off and never a meet a guy like you ever.
It's her choice to do that, its your choice to live a life that has passengers seats to a better existance.
