You got it confused
Men and Women alike tend to think that they can do "again" what he/she did "then"; believe that someone is going to put up with being taken for granted, used, abused, and unappreciated. You got it confused if you think you don't need to change something about yourself. Men and women take their chances on "trying" to get away with everything they can. We as creatures of habit refuse to accept that we can't go into a new relationship, job, or venture with the same attitude, expectations, and thought process. What didn't work the first time, won't work the next time.
