What made the big change in my life, what else, my marriage. There is nothing unusual in saying that marriage makes epoch-making changes in the life of everyone, both men and women. However, this varies according to the culture, you are born in and practice. I mean how marriage changed me as an Indian woman would not be the same as how it affected a person living next door following a different set of cultural practices.
I am not saying one has advantages and the other is rot. All have challenges.
