You are amazing, and wonderful and supportive. I hope your husband will continue to see the light break through his fog.
I don't understand what you said about Retrouvaille....that he would be put on the spot and have to talk. That isn't what happens at Retrouvaille at all. You listen to the presenters tell their stories. Then you answer questions about your feelings in a journal. Then the spouses exchange journals and read what the other has written and discuss it privately. There is no group interaction at all. Everything is very private, and the questions are not difficult. They rarely even deal with the past. Most of the questions help you to see your relationship in a positive light. For example, one question I had was: "Describe what you like best about yourself. Describe what you like best about your spouse." Not difficult to answer unless you have been blocking all positive thoughts about the spouse. In that case, taking the time to think positively is a breakthrough. And that is why there are so many breakthroughs at Retrouvaille. Because they show you how to think and discuss in a new way, a way that doesn't bog down in the negative.
