No, we've never done a WWME weekend. My parents used to recommend it from time to time, as they used to TEACH/FACILITATE them, but we've never done one. I honestly don't know anyone for whom they've worked more than short-term (I seem to recall that you came back all fired up, but since then, things have fallen back into the status quo?), and our lives are SO full with the activities of the four kids and both of our jobs, I'd hate to take all that time away.
I also have this aversion to "seminar" type stuff, from WWME to Promise Keepers and the like, as it seems like they always put the onus on the man to be more caring, more sensitive, say ILY more often, etc. I think I have the opposite problem going on -- too much of a "princess" mentality in the fetching Mrs. Choc.
