I understand now why your H is not on medication for bi-polar, and why you tried Retrouvaille without treating the bi-polar problem first. It seems to me that while he doesn't want to do the post sessions, and he doesn't want to do regular dialoguing, if he decides to have a big conversation with you regarding the relationship, you should insist that it be done in dialogue format. My H doesn't like to dialogue, and we stopped doing it regularly almost as soon as we finished the Post sessions. But, when we have a problem, we use dialogue as a way to resolve it. In my opinion, there is no reason to throw away what you learned over the weekend. It is still a useful tool even if you only get it out for the big jobs. And, you don't have to wait for him to drop the bomb on you. You can tell him, "I have something I want to discuss with you. Get out your notebook and let's discuss it the way we did at Retrouvaille."
