I don't necessarily agree that a D paper or one's behavior negates one's spiritual M vows, so to this day I'm wrestling with her relevance in my life. What she does will have to do with me if it affects S6 in a negative way. I believe that has already been happening, but not in a clear, extreme way. Merely a slow insidious theft of some of his happiness and security. But outside of the extreme, I need to keep it in the category of "not my business."
It'll be better for him and me for me to break from this DBing for some time or completely. Whatever hopes I had left are buried in my current disgust. I don't want to be friends with the kind of person she is. I think I'm done. Thank you all for your great support. You've helped me to grow as a person in ways I didn't truly believe were possible, and I intend to keep those changes going.
