I read your other thread, and what stood out to me was how you thought telling OM's W would probably end the A. Why would you think she has any more influence with her S than you have with yours? You thought her applying pressure to her H would end the A with your W. Maybe his W already knows about the A and is making threats like you have. Threats are non-effective when dealing with a WAS in an A.
This is not you doing work to save the M. This is you wanting somebody else to do the work.
How are you coming on the book?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
