Marriage is a historical institution which has generally been bad for women.
It forms part of a process in which women maintain society by their unwaged labour. I think the Gross Domestic Product , which is a measure of a countries productivity, would double if all the free work that women perform was included. Until the 19th century the legal age a women could be married was 12. A woman never owned herself, was passed from father to husband having the legal status of chattle, i.e. you were like the domestic animals belonging to your husband. Women were purposefully kept uneducated, except in domestic matters so that they would serve their role.
