Is it possible that we have not fully given ourselves over to God's will that his providence is sheltering these women from us? Would it not make sense then if we indeed desire a holy and viruous partner that we must walk the full path ourselves?
I like this point. God's providence is also sheltering us from ourselves, so we do not become the one who "causes one of these little ones who believe in me to sin." Worse than being thrown into the sea with a millstone around our neck. So if God keeps us away from good women who, because of our sinful past and broken nature we would harm and lead into sin, He protects both those women and ourselves from further sin and corruption.
The difficulty is, how to live in the world as a "monk"? I don't believe it is possible. We are among others and for many of us the temptation to sexual sin is too strong, or the temptations toward anger, hatred, depression, sloth, etc. while isolated are too great, that we realize the need of a female partner whether she is a good or bad woman. I think this is something necessary for our salvation that God knows too, and plans for us who are not deserving of the best women. We get what we deserve when it comes to women, in reality much better than what we deserve.
