No sting was intended, and I regret if there was any pain from what I wrote.
I can't speak to the numbers from DB since I am relatively new. A few years ago, however, there was a study done for couples who had attended Retrouvaille in the San Francisco area, and 5 years after the weekend about 85% of the couples were still together. Couples coming to RV are in a lot of similar situations in their marriages; however, the fact of them having chosen to attend together means that there is at least some desire or hope for the marriage for them. So they may be in a very different place than those coming to this forum.
Having seen firsthand what is possible for healing marriages, I am convinced that most marriages can indeed be saved. There is no magic bullet however. I have been saddened recently by the news that one of the presenters on our w/e are now divorced.
