How did Tanu become an abandoned widow?

Tanu's situation as an abandoned widow stems from the pressures and actions of her husband's family rather than her personal choices or circumstances with her husband. In the context of the story, it is highlighted that societal and familial expectations, along with financial motivations, can lead to the abandonment of women. Tanu's husband's parents desired to rid themselves of her, likely due to the stigma and burdens they believed she presented. This choice reflects the oppressive nature of a society that often prioritizes financial stability and honor over the well-being of individuals, particularly women, in a marital relationship. Tanu's experience reflects broader themes of social injustice and the struggles faced by women in traditional societies, showcasing the harsh realities that can lead to them being cast aside.
