She doesn't have your perspective. I get your frustration. It's a frustrating situation, but, if I may slip into DBing lingo for a second (Lord forgive me) . . .
it sounds to me like some of what your feeling is based on your expectation of what she should feel, or more that you expect her to feel as you would if you were her. You're not her and she's not you. She doesn't get the things you do, and you don't get the things she does.
And maybe she's a little afraid to tell you that, or not sure how to articulate it. I don't know. I'm really mostly probably talking out my fabled third point of contact, but these are the thoughts that came to me.
