There seems to be a lot of reactivity to suggest that there is only one way to approach boundaries. Part of the problem is the language itself. Another part is what you allude to, confusion about internal boundaries and the fact that there are two people involved of equal status - after all this site is about marriage, not children, employees, gypsies, or the like.
Actually this site is called DivorceBusting. What you advocate is for better communication and conflict resolution. Once again the "consequences" are for behavior that cannot be tolerated in a marriage under any circumstances. If you can tell us how to deal with affairs and real abuse without consequences then school us. Offer up a solution. I advocate what I have seen work here and in real life.
