Backpew (if you're still around), I don't know how many down-thumbs you got during the first 9 minutes, but people around here might have been down-thumbing Marriage Encounter, rather than you. Though I think Matthew hit the nail on the head pointing out your defensiveness in your first post.
Besides, one usually gets down-thumbs when one comments on one's own down-thumbs.
Why does your husband want to go to Marriage Encounter? Why not a romantic weekend away, just the two of you, somewhere?
My advice would be not to attend, but I would recommend you individually attend an Ignatian retreat. You would find it a far more enriching experience.
