Well, I'm a little confused. She was all pushy about having meeting to discuss finances and bring her father. She bugged the daylights out of you with emails, but now she has suddenly stopped? Why?
I think the reason she's reluctant to see the new MC you found is b/c your W knows you well and she suspects you've found a C who is pro-M. She probaby has her little closure speech prepared and didn't want to meet a new MC and have to go into details again. She wanted your old one or hers on that account.
I see no reason to contact her with these emails. The bills and things like that should be settled and stop this constant back & forth business.
I would not bring up the topic of seeing the MC again. If she brings it up.....stick to your guns about seeing that new MC (pro-m) you found and do not go to the other ones! Until that happens, I suggest you stay completely away and NC with her through emails/phones. If she calls....let it go to VM. If she emails.....run it by us if it's something you're not sure about.
Get out this weekend. Don't talk about the MR and find something fun to do. Take care of yourself for a change. This all takes a toll on you mentally, physically, and spiritually.
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!
