In a not too distant past, unmarried women used to live solely under domination of her father or older brother. When she got married, her father conveyed all his rights and authority to her husband. Among some cultures, in case of his death, a husband could also choose the next spouse for his wife, in some other societies, the wife was killed and buried in order to continue serving her husband in the other world. Furthermore, women were never allowed to study, so along these lines, it is easy to find out that in former times, to live a different life was typically not an option.
As the decades have gone by, and with the acquisition of rights, it is probably no coincidence that as women have gained economic power, they became less financially reliant on men for household necessities, therefore the decision to marry becomes more dependent on factors like love.
It is widely seen that women that nowadays refuse to get married are only a minority part. Mostly of them are still marked by hundreds and hundreds of years of oppression that are still being reproduced by their mothers and grandmothers from one generation to another. They are generally not familiarized to the idea of seeing an option to achieve supreme happiness by being single. Society simply contributes with this type of thinking, yet it is not deniable that women are aware now that they can walk with their own feet.
