Let it go...right now just stop all contact with her..until she comes back around and hits you up. Do not get sooo damn anxious and eager...
Some chicks just love to sit back and see how crazy one guy will go over her just to get her confidence up....YOU DO NOT WANT TO BE THAT GUY.
A move I implemented, after a date/hang out/get together, simply do not text her or call her(unless its absolutely necessary,example say theres a get together in a few hours and you want to take her) until she comes around to text/call you. Most of the time cant go 24hours without hearing from them
With flakage ive done the same shit, just stop contact. I remember clear as day this one chick pissed me off, I deleted her number(wasnt putting up with it, just done), several days later, guess whos calling....totally dropped the bulshit attitude she had.
Its on your watch and your time bro, not hers. Get it together.
