My guess is for whatever reason, this girl likes you but is not romantically interested. Otherwise she'd make the time. I don't know about the "trying to make you sweat" stuff, but if that's what she was doing, you'd be better off without her anyway.
And, tiltedbc, I really hope you meant "don't give her flowers or compliments too soon", not don't give them at all! Flowers and compliments are definitely a huge plus when trying to establish yourself with a girl!
But yes, we get nervous too, and if someone came at me with that stuff after one coffee date I'd be like, "Uh oh...maybe he wants too much from me." On the other hand, flowers and compliments after a one night stand will get you in the door for more nights and a possible relationship. Flowers and compliments the first time you meet will get you thought of as desperate. Also, when giving flowers, keep in mind what you'll be doing after that. Will she get stuck carrying them while you walk to the beach and back? In this case, flowers and compliments may come across as a bit clumsy. Just rambling, sorry.
