Much of it has to do with women being unable to be romantically attracted to a man that is not their superior. As well as women's inability to have compassion.

So quite simply, the ways in which he may be weak that she demands he not be, as well as the ways in which his behaviors or desires or thoughts disgust her, are not accepted by women, and worse, when she sees these things it diminishes her attraction for him and makes her feel less in love.

Whereas a man's woman being crazy, having fucked up or 'disgusting' desires and thoughts and behaviors, doesn't make him love her less, and really is only an issue when it hurts him directly in a significant manner, like breaking his shit that is highly valued or causing stupid amounts of physical harm. Men's capacity for compassion allows them to understand why a woman has these desires or thoughts and behaviors, and accept them anyways.
