Ps: practically every man thinks he's a strong man, but most of the time he's just a weak man. 

And that's where the resentment also comes from. It takes a long time for a man to mature. Aristotle said that “a man only becomes a man after 35”. 

In a society in which practically everyone is looking for easy pleasure, sex, the moment, carpe diem, it's guaranteed that men and women will get hurt, will resent each other... simply because they don't understand, they aren't mature enough, they haven't been taught a good hierarchy of values.
