I don't consider my W filing BD as her mind was set. I think it was just a continuation of her threats saying "how day you attack me, I am the one that's mad and leaving you" (that's not what I did). Do you have any evidence? Him being in denial is normal, that's what the "just friends" theory is based on. He doesn't even realize it's an EA. My wife argued the same thing until I mentioned "if it was the other way around, and I was texting an attractive woman I worked with several nights, until 4am, while your not around, what would you call it? Would you be mad?" and her tone shifted a little bit. (she got much angrier, yelling, furious, etc, and that's about when she stormed out)...
