It has been noticed that there is little motivation for women to be nice nowadays. If you find a nice girl it has to be because of an extra ordinary amount of effort that she has expended on correcting her character traits. Otherwise, the emphasis of society is to make women as nasty as possible,-- and that shows. The proof is in the pudding. Women nowadays are unlikable.  If they have divorced  their husbands, they get tons of praise for being so brave. And the more damage they can cause to their ex husbands, their friends and general society consider her as a heroine.

The reason for this I believe is מכת מדינה a general plague that has come into the world.  For you see in prayers of Jews a few generations ago, their main concern was Parnasa -making a living. In general prayer books, you do not see much about peace of the home. That was assumed to be ok. In the American Civil War, how many letters do you see of women or men wishing for their spouses to be better? Never. All the letters and prayers of women are, "Please bring my husband back home safely"

Western society has changed. Women think of divorce as getting  merit badge, and think of it not as a way to get away from their husbands --but as a way to get all his money and to ruin his life as much s possible. 

[What I am getting at here is the importance of Rav Israel Salanter and the Musar Movement -- that movement he started. The message is everyone ought to learn Musar the  more the better. Musar in this context means four basic works חובות לבבות, שערי תשובה, אורחו צדיקים ,מסילת ישרים three were from the middle ages and the last from Rav Moshe Chaim Lutzato.
