In my opinion, you made it through this week alright, so I don't see a need for much change. More confidence in your stance would be helpful. Puppy's advice on how to ask for some space is good. I think a little distance so that she is looking forward to the opportunity to really talk to you at Retro will be good. You should refuse to engage in any R talks this week. There is plenty of time to do that at Retrouvaille, and they will structure the way you talk so that it is constructive on both sides. If the subject comes up, just ask her to hold that thought until you get to Retrouvaille, and then you will discuss that and more. Much more.

Do not try to be distant at Retrouvaille. when there, follow the directions and be as open and guileless as possible.
