Don't intend to start a love marriage vs arranged marriage debate , both have their merits and demerits . But I always thought that one one advantage of love marriage would be that the woman knows her partner well before marriage and there are no surprises / shocks with respect to her partners general behaviour and nature. But from this forum I realize that's not the case . Many women find the man they married and the man they fell in love with to be two different versions . Why does this happen? Is it because dating is still taboo and girlfriend boyfriend actually spend very less time with each other before deciding to get married or is it because men have a different behaviour when they are in the pre marriage dating phase ?
