Ya Dodo.... I can relate to that perspective. Perhaps not as clearly defined as your experience but I do see more tolerance for the WAW than the WAH. Perhaps given the expectation for a many to be the "Spiritual Head of the House" it is more an abdication of responsibility in this context. In addition, I can't help but believe that some women can portray themselves as the hapless victims of their "opressive men" (sorry ladies... I am not painting all with same brush... just giving a narrow viewpoint of some I have experienced).
I think some women have an easier time rationalizing themselves and being viewed as vicitms. I am probably ruffling some feathers by stating so. I am speaking largely from my ex's perspective too. She rationalized this way. "I got married too young. He is never around. He changed since we first got married. etc, etc." While none of these are necessarily incorrect, they do not represent a balanced perspective.
Again.... sorry ladies if this is offensive.
I simply agree that there appears to be more empathy and less judgement for a woman walking away from a "Christian" marriage than a man.... in my experience anyway.
