Perhaps if the property settlement were always decided in favor of the defendant in a D (the spouse who did not file), then perhaps people would think twice about breaking a M. Or be extra careful about who they M in the first place.
I am beginning to think that the spouse who wants to dissolve the union should be prepared to forfeit all rights to deciding property and custody. Walk away from your commitment, walk away from it all. It certainly beats what we have now, where the wayward can reap the windfall.
