Retrouvaille is going to be in my area next month, so I was contemplating this myself and struggling with whether it would have value for my R. I did a lot of reading on these forums and elsewhere and the conclusion I came to was that Retrouvaille renders amazing results when both spouses are willing to work on the R, but poor results when one spouse isn't interested in reconciliation. They advertise a 90% restoration rate, but that's only if the couples went to all the followup meetings and that only happens when both spouses are committed to it. In the end I decided against it, I'm positive my W would just see it as applying more pressure to reconcile and it would end up being a big backslide in my DB'ing.
