You are exactly right in your post. The majority of people would admire someone who can stand up for themselves but also stand up to thier commitment in marriage and try to do the right thing. At this point, our wives are in a situation where they do not want to seem weak. They have made it known to the world that they are strong and can walk away and be fine on thier own. So going back to the situation would (in thier eyes) make them look like they have no backbone. It is a sad cycle.
I also agree, we have let them down. My wife has taken letting me down to the extreme. Anything she can do to jab the knife deeper in my back she has done. You would think i cheated on her or beat her. She literally has treated me like we have only known each other for a month. I know the treatment is to make her feel better about herself and try to get a rise out of me so she can validate her decison. I bit during the early on stages of the D but have been in extreme control since march. which i am proud of.
