I have never been to Marriage Encounter. I overheard some people at the Retrouvaille weekend talking about the difference between Marriage Encounter and Retrouvaille. They said that Marriage Encounter is not for troubled marriages. That is doesn't deal with the problems of troubled marriages. Retrouvaille, on the other hand, is specifically geared to troubled marriages. It is often attended by people on the brink of divorce or separated. It is recommended by divorce mediators and some judges, before divorce.
I think you and your wife will benefit greatly from Retrouvaille because it specifically deals with how to communicate without going round and round. I mentionned to my husband last night that we haven't had an argument in the 6 months since we completed the Retrouvaille training. He smiled and agreed. That is unbelievable. We used to argue constantly -- if I said it was a nice day, he said it was awful...and vice versa. We just disagreed about everything. Now we get along. Amazing.
