Not getting a read on your W now maybe a sign that things are shifting. Just step back and think about things - if you change what you do and she changes her response then what shows up is new feelings for both. But it doesn't mean that you can't read her - it means that you have to let what you know about her in the past to catch up with what you see and do in the present. (was that too confusing?)
It would not be wise to do anything you are not prepared to handle. What do you have to do to get to that point?
Just a suggestion, instead of describing yourself as "stuck" try using the words- "staying the course" (or come up with your own) instead of "lost and confused" try - "figuring out what has changed and/or what is working".
Then, I think you have to see that she cares about you and maybe more than that. "More family time", "better mood", "stopped talking about the future without you in it", "worried about you", "not bringing it up".
She's giving you space, time to digest, but she could be using it as an excuse for having doubts or slowly second guessing herself.
