I met this girl from OKC, we had a great time last week, she even texted me later that day and the next to see how I was. I asked her when she was available again and she said her week is full with work and that she's not available till next thursday, then she continues to email and text me after that.

Would this be a lost cause or possible?

Nice username, definitely a great game

If she continues to keep in touch, it looks like she's really into you but still wants to maintain space to keep things from going stale - which is good. Either that or she really is busy with work. Its odd that she transitioned back to emailing though. You don't want to end up right back where you started again. Be yourself but always maintain that image of higher value. Ask her out again for Thursday. If she flakes out again, this chick might just be keeping you as a back up plan.

Yes! Like the guy above said, she's really into you, if she keeps initiating contact.

Don't start to chase her. Let her chase you. I think this is the biggest rule to get that magnetic attraction after the initial attraction: people always want what they can't have. So let her chase you, not vice-versa.

I'd stay in contact for about a week, maybe more. And gauge her schedule and learn when she's not busy. Act like you're the busy one. Then all of a sudden say plans fell through, got an unexpected day off work, or whatever.... Then spring a meetup...

Good Luck!
