Many an author through the years have suggested that women have just a bit of cray-cray in them. And there are probably good reasons that they suggest this. Undoubtedly a good portion of the Patriarchy existed for the reason of reining in this cray-cray. The Patriarchy no longer exists, and the cray-cray of women is now indulged.
Women undoubtedly can sense their cray-cray as it comes bubbling up. In times past, they would need to keep it under control, as their marriage prospects / current marriage depended on it. This situation is no longer the case, Many men are so desperate that they will marry cray-cray (perhaps some do not know what non-cray-cray looks like). And it is after the marriage ceremony that that the flowering takes place; for there is no longer any reason at all for a woman to keep it totally in check. So it starts coming out more, bit by bit. But there is no problem here. She can frivorce him and be financially rewarded for doing so.
And women do just that. Frivorce, and collect cash and prizes. And then they no longer need to keep whatever mental issues they have under control at all. So out come neuroses, BPD, NPD, etc. in the worst case, and more minor issues in the typical case. And if the husband during the marriage pointed out the various mental issues that she was having; well then, out the door sooner he goes (perhaps this is a blessing in disguise).
So in conclusion, one might suggest that the biggest enabler of mental issues is no-fault divorce.
