Find another chick. Reason being is that you got too serious with her for a second date, and you chickened out to call her. She thinks you're desparate. If you call her now, tomorrow, 3 days later, or 10 days later, don't matter, she still think you're desparate.
She got your message, read it, and if she wants you she responds..
What you should do is not call her, instead move on to the next big thing.. Doing that tell her that you are not desparate and you have some value, if she recognizes that she will call you or bump into you sometime, BUT, move on with assumption that you never see her again.
Forget her, 2nd date man, dinner... Serious... She don't want to get married, she just want some fun.
Should you decide to call her, she will make some excuse, or tell you ok to call her other time, or something, but you will not go on a date with her. Like I said, she thinks you're average and bellow her standard. You can confirm that by calling her. Either way, whatever you do, if you're with me PM me your e-mail, I got something for you.
