I did take part, but exH turned out to be very confused about his sexual orientation, so communication wasn't the main problem with us.
The programme felt strange as it required us to write form letters to each other, set aside time to write and read the letters each day, and really listen to each other, alternating turns. A bit forced, therefore, but the wisdom underneath it was obvious, because communication doesn't happen automatically, and when it leaves the building it's hard to switch it back on without a model to work on.
The initial weekend retreat that we went on featured the mentor couples telling the story of their relationships up to that point. Then we spent time learning to write the letters and to listen and show interest. On the follow up weekends we went through personality assessments, looking at our families of origin, many other forensic type exercises, as well as doing the letter-writing. The idea was to open up to each other, rekindle the art of talking to each other, find the spark that brought you together in the first place. The programme also offered the chance after all the meetings were over to attend gatherings of other couples committed to their marriages, so very committment-friendly and with good will on both sides I think it would be a good idea.
I got the impression that some of the husbands had been dragged kicking and screaming there, and it's not for every relationship -- a no, no if there's ever been DV for instance, and obviously nothing could have salvaged my particular relationship. But the men who spoke were impressive, and you could see even the reluctant husbands pricking up their ears.
