@KC: I'm really sorry to hear about that.
If you really want her, i think you should put aside your pride for a while and make an effort. I'm not really sure what is going on, by the way you describe it, but some of the thoughts that occured to me are:
a) Maybe there's more reasons to it, like maybe there has been someone else flirting with her (and thus making things more interesting to her). Try to talk to her and see what the real reason is.
b) Maybe she is bored and this was her way to stir things up a bit. Maybe deep inside she just wants to see how much you care and what you'll do about it, if you'll do something to make things more interesting. Maybe she hasn't made a final decision yet and she's just as frustrated as you (and that's why she's acting all bitchy). Maybe she's bitchy because she's thinking that you aren't doing anything about it. I know this probably doesn't make much sense to you, but the female mind never made much sense to any male.
Bottom line is: if you really want to not break up with her, make an effort to make things more interesting. It'd be a shame to just let something so wonderful end like that. Even if it does end, you will have at least tried.
As for the NF: meh. very meh. i'd really need someone to talk to tonight, but noone's online. i feel kinda lonely and a bit like things are slipping through my hands. :/
