I hear you man. You, me, Billzfan and others must be in the same boat.
How much do we say to the kids? If our household has some peace how much do we rock the boat? Do we put our foot down and risk divorce to keep the kids free? Would that just push the kids further in?
It's like trying to get a sliver. You're never positive of the right tool (needle or tweezers) and if you use the wrong one you could push it further in. Plus, sometimes getting the sliver out leaves a lot of raw flesh around the wound because it was in so deep. (((sigh)))
