i'm not so sure about that "not communicating" part of yours. your girl clearly needs someone who will really be there for her. she's in a very bad situation and i guess the thought that everybody could just leave her anytime and the thought what had happened to her parents might also happen to her is definitely freakin' her out. so she's trying to get herself unattached as possible at the moment coz i think she's so afraid of everything. again.. she's too confused of what she really wants at the moment due to some factors affecting her state of mind.

i bet she's trying to see if you will really stick to her no matter what. that's how i see it.
