Ok, well, lets pretend for a minute best case scenario has happened and the situation with your W and her friend has been solved in a way that is suitable to you. Then what? What else do you feel needs to be addressed in the R you share with your W?
I ask this because if your efforts to mitigate the damage you feel your W's friend is causing and the steps you have taken to rectify this problem have not worked maybe there is something else you can focus on.
