I may have missed a few pages from your threads but what I have read seems to be game playing.
Your W has consistently said and pushed to work on M. Why not go down that road. Determine what you want in a M and what she needs to do. It goes without saying you need to work on your side of things regardless.
Why not give her the chance to SHOW you she wants to work thus out? It will soon enough be apparent whether she is committed or not
You need to figure out what you want and take steps towards that.
