Be careful of W's shell game. She's now attained a Black Belt status in this. Wow she's really good at this! She's trying to buy time with this MC talk and not really putting real work in it by drop kicking the OM to the curb.
I've seen way too many WAS go the MC route and then say "Well, I've tried."
I'd move forward with the D.
X3 ... I did MC thinking we were trying and for some reason could not connect with W ... turns out OM was still in the picture pursuing her. Lesson learned and now I have things in place to protect myself from that happening again.
