I think being direct with Mr. A at this point is a good idea. I mean, you are divorced legally now, so DBing to get him back seems to focus a lot on the WAS actions. DBing efforts for you (GAL, not pursuing) are still applicable. But doing things like avoiding R talk and trying to show him the better you are not really as pertinent at this time, IMO. He needs to show that he is improving, too! Now it is ok for you to lay more on the line because what do you have to lose?
And, Mrs. A, really and truly think about what YOU need. (It is also attractive to the WAS because it caused them to respect that you aren't a doormat and have standards. It makes you more attractive) I know you will be tactful about it!
I am so hopeful for you! Good news that he is regretting his actions.
When you asked how they "prove" they are serious....well, I think this comes when you lay some conditions out and they follow through.
What is the first step you need from him? MC? Retrouville? You can even try not to overwhelm him and just say "first, I need___" Is it a commitment from him saying "Yes, I will go to MC with you?
Exciting stuff!
