I'm not agreeing. Children deal much better with a reconciliation than the alternative.
Fair enough. I think the added emotional, mental, etc energy of reconciliation creates comperable (though not identical) stresses when compared to quitting and cutting your losses.
That's not to say identical stresses or identical harm, but probably comperable.
Basically, I think that if reconciliation works you are more right than I am. But I figure the odds of a workable reconciliation are worse than the odds of an unworkable reconciliation, which harms the kids as I suggested.
