I just moved into this board ("Facing Life with a Smile and a Wink") ---I'd been posting on MLC.
I can relate to everything you're going through, and all of your questioning.
I wonder if they know how often our stomaches sink? We've gotten so used to the roller coaster, we're still reacting to the ride.
Have you ever been to sea? I don't like boats any more than roller coasters, but was roped into a family trip on a boat for a week.
When we got back to land, we still had sea legs. We still swayed, the land didn't seem stable---my H couldn't even drop a kleenex into the trash can once! It kept falling to either side!
That is where we're at. The ride is still going on internally, even if our S's say the ride is over.
As far as how our S's could descend into lies, backstabbing, cheating, I came up with a theory on how they could. It doesn't EXCUSE them, it just explaines their reasoning.
I'm going to put it in the next post, because my machine has been freezing up...
