Like right now u need to "man up". And stop killing yourself, over if she should call or not. Who cares if she does or doesn't. U are just stressing yourself out over a girl u jsut met 2 weeks ago. Lsiten to your self 2 weeks uago u where fine without her and now u are sounding crazy.
The lunch thing good idea.

The card bad bad

. You are a guy not a girl. You should of sucked it in a asked for her number yourself. Not given it on a card. Come on!!
Just go on with your life and act as if you never met her or you will just make your self sick till then.
