What do you think is the difference between the folks who are here, say "Surviving big D" versus the ones who are split many moons and/or in "MLC" or "Infidelity"?
The folks who are here, for the most part, know that their marriage is over, and they know that they are getting divorced. The folks in the other forums you mentioned, for the most part, maybe still have some hope that their marriage will work out and are still 'working on it'.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
