Most Helpful Girl
I´d say move on. She doesn´t seem that interested in you, and I know thats not what you want to hear but you wouldn´t want to be in a relationship with someone who doesn´t care to reply to you anyway. Believe me, the best thing for you its just to move on. There´s plenty of other girls who deserves your attention more than her, and you will only realize that when you let her go and find another one.

Best thing you can do is say give me a call if you change your mind. Walk and never look back. No calls, texts, emails nothing. Not even a happy whatever day it is. NOTHING!!
An ex is in the picture now and she has more emotional investment in him than she does you. Maybe it will work out maybe it won't.
Only thing you can do is move forward with your life. Your next great love might be around the corner. Just don't focus to much on someone who doesn't want you.
I hope you find the happiness you deserve.
