I couldn't agree more- last week OM and I shot some texts back and forth- I said I don't keep anything from my W.
OM said- "she's not really your W anymore, hasn't been for a while now."
OUCH...and I knew it too. I had told W she cannot believe she's married one day and believe she's single the next...the rest is history.
I feel for you DDogs- your W's father sounds like mine- seems like he would be a good ally to have. I don't know about the question you pose- I think Puppy would be a good person to weigh in on the subject- I think it sounds pretty good, so long as your exit is done correctly and as a confident gentleman.
