Sounds like you just want to move forward one way or another. That's ok, but if your W needs more time would you rather wait or are you ready to let go. Doesn't sound like you want to let go.
Somehow I think you need to have a serious convo about what you want and what she wants. In other words, what will it take for her to work on the M and what will it take for you to work on it? Make these things specific and needs. What keeps you from having that convo with her?
