Quote: Is there any way to change who she's talking to at this point?
NO.
Jason, in following DB principles, you will see that it is about changing YOU and your responses to things. It is not about controlling your spouse.
For the best input here, you should give a synopsis of your situation. Maybe there are things that you need to change/fix. In doing so, even if you cannot change who your W talks to, perhaps you will change what it is she is saying!
