For clarity about the 180, I believes she expects me to stew on this all day, and unleash holy hell later - she even commented as such. Always testing.
I'm going to let it go and focus on me. . . .
OnMyWay,
I could be wrong, but in reading your backstory, it seems to me that "letting it go" is hardly a "180" for you. In fact, I think that's what she expects you to do. Or perhaps you've been "passive-aggressive" in the past, and would veer between meekly letting things like this slide and then an angry outburst about it.
I think a middle-ground, "lovingly but firmly" as I mentioned above might be a TRUE "180" FOR YOU.
