Gordie is spot on, I just want to add do not try to analyze and rationally understand what she is doing, there lies madness. She is not rational, she is fractured. It is as if there are completely conflicting set of desires and personas in action. So if you try to read tea leaves you will go mad. You are seeing the confusion and contradictions in her behaviour,

Maybe this will make it clear: when they are in incredible pain and need support from person closest to them they cut off and alienate that support. Does that sound rational?

So stop, stop analyzing, stop looking for signs and accept she is lost. For now. Detach, let go, move on. Otherwise you will realize soon that you are in so much pain that you may drown or hate her so much you never want her back.
