A necessity? Mmmm, that might be a bit strong. Marriage does tend to bring security and wealth, though. Although I joke about getting married ('Don't do it!'), I generally think that a woman is a good influence on a man, whether we like it or not.
Not a necessity at all. But I think most all the women get complete when they get married and have children. Though there are some women and men also who prefer to remain single.
Its necessity of Society !! It always happen both of the partners fight !! Its a Band that sometimes makes them to stick closer and try to forget fight.
