1. Actually, I thought that we were in a really good place, but we were having SO much trouble talking about feelings, and getting caught up in trying to understand the other person. But I went in to Retrouvaille thinking, arrogantly, that we were going to make it and that this would be a really nifty little technique to help us along our flower-strewn path to R.
2. Yes. And when I say yes, I mean because, during our post-sessions, I left the house twice and we went through an in-house separation that I meant to end in divorce. Because during that time, I found out that my FWH was lying to my face about his purging of porn, and right after our post-sessions were over that he was private browsing to get his porn fix. We kept going to post sessions although there were two weeks that I just sat there like a zombie, with tears streaming down my face. And at the last session, I told the group that I didn't know where we were headed. But we kept talking. Even when I did a modified 180d on him, we used the techniques to speak to each other.
3. It helped us to talk about it. It helped us to explain our feelings about it. It helped us to communicate, effectively, so yes. I think that it helped us get through a big chunk of healing in a quicker fashion.
Of all of the couples that attended with us, there were, I think, well over 1/2 that were headed for divorce. And a lot who were just miserable and showed it. My advice? Go. You have literally nothing to lose. And a lot to gain.
