the urge to talk to a new girl, especially one who you are attracted to and is showing ioi's back at you, can be overwhelming. I used to always game girls as much as possible and as quick as possible using all forms of communication e.g email, text, facebook, meeting up etc. You could be the most intresting person in the world, but if you show all your cards as soon as you get to the table, your never gona win. As the poster above says, ease off a bit, be busy, shes not the only girl in your life and if she is, pretend like shes not!
Just remeber that you are a busy guy who has a number of important things to do except talking to her.Another thing you can do if freeze out for a while, then after maybe a week of not talking to her, and im including not talking to her even when she starts to open convos with you let her know you cant talk, your a tad busy SPAM (just for this week), then open her again with a 'open loop', e.g 'omg...just saw something that reminded me of you', i have yet to have a girl not text me back or facebook me back when ive used this message. Just rember that she will reply with what, dont answer with your next message. When you do tie up the loop, make sure you start a new one just before hand so you always have a new open loop to keep her intrest going
