Marriage in my grandmother's generation was like one man for theirs lifetime. Either it would seperated by death or divorce, they would remained faithful for one man.
Marriage in my mother's generation, baby boomers generation, it was like a trial and error. If the first marriage didn't work, the second might work. If the second still didn't work, they will apply the saying of the third time lucky, and so on until they find the right man who can support their life and their kids, or until they got tired of men.
Marriage in my generation, millennials, is like will never happen or will happen so later in our life. We are sufficient economically and emotionally, we don't need a man to define our life or to make our life happy.
