I really don't have much idea, however, anytime the WW hangs out with female friends that are not friends of the marriage.........stands to receive vindictive advice to use any means to get everything she can from the settlement.
From this point forward, you may need to see your W and yourself as two separate entities. Unless she goes to you freely and sincerely wanting to do the necessary work to save the M, you cannot divulge the information you hold. There have been H's who were so desparate for things to be like it once was in the MR, that they would open their big mouth and spill everything. In their mind, they thought it would bring the results in the W they wanted, but it doesn't. The W would actually take advantage and use it against him.
I suggest you try to not watch her, and begin preparing for a new life. The more you can emotionally drop her, the better you will come through this ordeal. Keep your side of the street clean, and she can do whatever with her side.
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!
