You are beyond me. You and your wife have a unique, bizarre, interesting, different (choose the adjective you like best) way of interacting. I never know what to expect when I read your post. Will you be nice and she'll be off the wall, or will she be nice and you'll be tempermental? All I can say is, I think you know how to handle her. It's like a dance you two do.
I think it's great that you are manipulating her back into Retrouvaille. There is a lot that you two can get out of repeating it. And this time, you need to continue the dialogues, and you need to go to all the post sessions. There is so much to get out of the post sessions. That's where they talk about rebuilding trust and forgiveness. The weekend doesn't go that far. It just teaches the dialogue technique. You guys need to do the whole thing, and then practice, practice, practice. Trust, forgiveness, commitment, love --- all decisions. All necessary simultaneously to support the relationship. Without any one of them, it's just a house of cards waiting to fall down.
