I think it's unfair to demand women be like men, for decades, and then blame them when some of them eventually go a bit insane.
Womens' intense need for safety and security is the basis of pairbonding and nestmaking, and it protects them from harm or capture.
Married women are the safest, because their mates tend to be better behaved, they engage in less risky behavior, they live in safer neighborhoods, and they are inconvenient targets for strange criminals. Making women terrified of marriage, in particular, has been a disservice. Feminists decried this as "the devil you know" tactic, but obfuscating where real danger was most likely, left women simply alone and afraid of all men, which sometimes warped their minds.
