Change is a process, it takes time. If you make progress, that should be enough. As I understand it, the goal is to get through the next 2 weeks with no further damage to the relationship, and get to Retrouvaille. I think, like the others, that there are many things wrong in your relationship. But I don't believe that you can fix them all by yourself.
The point of Retrouvaille is that they explain the rules to both of you, and you both think about and deal with the same issues at the same time. Right now, you are dealing with issues, and she is thinking about other stuff. If there is no direction, there is little chance that you will end up at your goal. But that's fine, because you don't need to fix this in the next two weeks. You just have to keep it from getting worse.
I think you are doing fine. You are making her realize that divorce isn't all peaches and cream the way she imagined it would be. She needs to see that. It sounds like your wife lives in her own fantasy world and she expects that her fantasies will work out the way she imagines them. Maybe in the movies, but real life is different. I think you are doing a good job of showing her that she has some unrealistic expectations.
