snootch.
Cross between "snatch" and "cooch?" I like it!!! Mind if I use it- even without your permission I will go ahead and do so anyway!
Boost- she's blowing you off. You just got owned by a female, ambiguously. If she said "It's not you, it's me" it's either A) there's another guy(s) involved B) it is YOU or C) BOTH.
Remember there are plenty of fish in the sea, get out the pole and throw it in the water with some good bait. If you don't catch anything, just keep trying. Because everyone knows that if you don't try, you definitely won't catch shit!
If you do talk to her again, and the conversation heads in the same direction of "I'm not sure what I want, it's not you...etc..." I say do a couple of things; one tell her that you don't want anything and you don't want anything serious. As well, when she says that she needs time to think about it, pause BRIEFLY and your retort shall be "Good, I didn't want anything serious anyway. You know where to find me" and hang up.
Don't let her play games with you. But don't play games with her either.
