I agree with Pei about the difference between DECISION and RIGHT, but I also respect your position that Walking Away was the equivalent of escaping instead of facing a problem.
But, let's take into account perhaps she wasn't emotionally able to face the problem or work on it at the moment. I do respect the need for privacy, even in a marriage. A healing time, so to speak.
I'm a great one for straddling the fence on this one, aren't I? I just really try to look at things from both, or all, perspectives. Of course, I thought that made me a great partner, obviously I missed something.
