Justin,
OK...now I am laughing my A$$ off..that is just plain funny.
I can think of plenty of nicknames. The usual ones, the "b" word, "s" word, "w" word, all those traditionally degrading words that we like to use when describing philandering women.
I made a FATAL error when all of this started, and called the OW (called her all the way in India, if you can believe that). I tried to implore with her that she just go away. I tried to explain how it would destroy my family, my children, our lives, and how she had no right to all of that (in her letter to WH, she would even refer to MY children as "our children"...like I was just going to fall off the face of the earth or something and she would step in as his wife and co-parent of my children). I tried to explain to her my faith, my God, how this would be a total betrayal of my WH's faith, his innermost core beliefs about right and wrong. She started to tell me that her religion (a third world religion that is TOTALLY counter to my Christian beliefs where I know that there is only ONE TRUE GOD, Jesus Christ) also had rules about religion. She told me, and I'll never forget this, that her "religious book, the blah blah blah [couldn't remember it if I had to] was written in the 1400's and we have to accept that the world is different now. And many of those teachings are obsolete and not applicable to our lives now."
I was floored. I told her, "Well, WE believe that our Bible is, was, and always will be. It is timeless. And the struggles, and solutions to life's problems, are universal to the human spirit, despite the century they are living in."
SO NOW, I just choose to call her........
EVIL.
