So.... Has there ever been a time in which your W was able to emote and express her innermost thoughts? What is she passionate about? How can you tell that she is passionate about that?
It is important that you know what makes her tick, what revs her engine, and what it looks like when she is "into" something.
This may not be easy, but there must be something that we can examine to better understand her and to help you get closer.
Don't ravage. Don't push too much. Give her some time to process.
