Hmm... Since that is the case...
You got together for 2 months only from what you said.
For a budding relationship, It takes awhile to understand her,
and she to you.
I think she is uncomfortable or unsure how to be candid with
you. The good point about you is that
you care for her. Although the easiest way is to overlook
her shyness (or what-nots) or just pretend this issue would just go
away by itself, you are caring/ mindful enough to seek
help on how to maintain an open communication with her.
Tell her that you do care for her and being candid is one of the
first ways to build up a mutual trust.
It indirectly breaks her out of the cocoon that she
has hiding into all the times.
Certain things cannot be rushed when it concerns something
which is as complex as a behaviour.
For now, you have to go slow on her. She already knows that
you are willing to be a listener for her, so let her approaches you
on her own free will.
Pry her out from her cozy cocoon once in awhile. She has to face
up to reality sometimes soon.
Cheers.
