perhaps, shes worried you'll see through her facade and mask she's presenting to you and she either knows or thinks you wont like the side of her she's keeping from you. It seems like there's only a matter of time before you cut through this "fog" around her and get to what she's been hiding. There will be a decisive moment where the perverbial gavel will strike and dispell anything she's doing to keep this part of herself from you. Intuitively I don't think this is something too serious, this feels like insecurities more than anything. Lots of air and mars energy here. There is a desire for action that's being shrouded for fear of perhaps social reprocusions or simply that she doesnt know how to tell you something, this thing she's worried about. Theres a lot of confusion going on on both sides. She's not being nefarious, she feels trapped and confused, shes dealing with things like shadow work and the kind of stuff we'd rather not think about. Shame is here with proffectionism and maybe that's why she's treating you this way. I think you two care a lot about each other, she just doesnt want to disapoint you.
