This is a cruel track, putting more stress on Aarti and the decision is not going to be easy for her. However, she says she wants to have the baby at all costs, even her life. Now, think about it, how is Yash supposed to bounce back from a second wife dying??? She needs to think of what she will be puting her family through should anything untoward happen to her. I feel for her because no woman wants to have to make that choice but she has to think of the aftermath, and the doctor said that she can have another baby.
I really don't like how she's been acting since the fight and she went home, what she should have done was talk to Yash and tell him that she understands that he don't want her a conventional wife but she will stay for the kids but for her to lash out at the kids and ignore him is a bit much. Be a mature woman and lays the cards on the table.
