Re: Contact her, wait, or just forget about her?
Giving her the outs was nice, but risky. She didn't take it so you got lucky. She is interested. But I wouldn't have told her to contact you about if she's free. Now you risk looking needy if you contact her. Next time tell her you will contact her a little later in the day then don't contact her until the next day.
But you've got no choice. Hit her up and set something up ASAP. The time constraint just means you have to work faster. Take this as a challenge and don't give up so easily. It takes roughly 7 hours to build enough comfort with a woman that she will sleep with you. Two weeks is plenty of time. Go for it man and push. This is your challenge so learn from it.
