In my case, exposure worked. But part of it seemed to be my understanding of what level would work on my W. I knew that "over" exposure would equate to shame for her. Our M was at a fragile point and shaming her may have pushed it too far. But it still needed to be exposed, and it was. Just enough to get her to think about what she was doing and that I knew. Limited exposure worked in my case to end the A.
