Until your W comes back to you and says in no uncertain terms "what will it take to fix our M?", all your time snooping is pretty much time wasted.
You will drown yourself in a sea of speculation, and whether you are guessing correctly or not will make absolutely no difference to the outcome.
Use your time more wisely. Use your time to figure out what you want to be and where you want to be. Figure out the steps to get there and start on your journey. Don't wait until tomorrow, start now.
If you follow that journey with conviction, you may find people joining you, maybe even your W. Perhaps not. And if she doesn't, it won't really matter since you know you are on the right path, with conviction, right?
Realize that your value is not in chasing your W (or anyone else) in circles. Pick a point, draw a straight line, and go.
