I know, b/c that comes from the root of NGS. You have read the book on NGS, right?
You need to understand why you feel you must always be nice, even to those who have cheated, lied, betrayed, and whatever. Your answer that it's just you is the typical answer I get from those nice guys when I point specifics out to them. I believe them 100%, b/c it is ingrained that much.
Nobody here is trying to turn you into a jerk. We want to help you recognize where to draw the line with those who disrespect you. I may be wrong, but I think whenever your WW is being civil in conversation, or when she's even being what you would think as "pleasant", you automatically respond with too many words, and can get somewhat gushy. It's as if you temporarily forget what she is, or else your NGS tells you she's being nice at the moment so you must respond accordingly. However, in most cases I've read, it is the WW keeping the LBH emotionally engaged so he won't treat her like she really deserves. And, as I said last time, it's just how the WW works in manipulating him. It's like she keeps him ready to be used whenever she decides to play that card.
When you can overcome the pull of NGS, you will find a sense of freedom, self-respect and confidence like you've never had. These are not my original words, but words from men who actually lived it .
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
