Well, I think you should maybe communicate and ask her if something is up 'cause she's been short and snappy with you and if she says "nothing", and doesn't engage in a convo, let it go. If she continues to act all crazy then you can let her know that it is not ok the way she's acting towards you. If she is unwilling to communicate at that point, give her a taste of her own medicine. Retreat, be aloof, don't ask her ANYTHING and don't do a goddamn thing for her. Let's see how long that lasts. Could be the beginning of the end if no resolution is met. In the words of George Costanza, you need "hand".
