what will happen to Robi?

Robi, a small town women, lived with parents and 8 siblings. she didnot completed her school. she was the last child of her parents. Her father worked in a government office, so when she was only 18, her parents became depended on their sons. None of her brothers were ready to take the responsibilities of Robi. Her sisters were helpless because they lived in their husbands' family. As a result, Robi did not get married. she was not educated, so she did not have any job. she never tastes freedom in her life.
Now, she is almost 45 years old. Her parents had died. she is still protecting her virginity. still she hopes that, one day she will get married! still her sisters are trying for her marriage. Recently she is living with her elder sister, who is an widow. she doesnot have any place to live. she have to live with her siblings family. Her nephews and nieces do not treat her with respect. For them, she is not different from the maid who works in their home.
sometimes when I think about Robi, I become worried. what will happen with her after her sister's death? I don't know. If she was educated, today she might have another life. if she got married, she could have a family. she is not educated, not married. she can not depend on herself or someone else. I don't understand, why she didnot ask for her rights? why she didnot choose a partner for her? I want to know, what she thinks about her life and herself, but when i go infront of her, i cannot ask the question.
