I feel that Sona will not leave Dev like Neha did but will fight it out. Because thats how our bahus think and behave.Once married it is forever.
We are supposed to dislike Neha for her decision but like Sona who is trying to become adarsh bahu ((Dev said so).
If we take Gopi Bahu as the epistome of adrash bahu. Sona will make noises and argue unlike Gopi bahu but she will undergo all the torture. Yesterday she cried for the first time after marriage and it will not be the last time.
By the way why Bejoy is so rude to Dev?
Why Sona wanted to talk to Neha when Neha wanted to be left alone? She should have waited for the right moment. When Neha herself may approach her. But Sona wants to be insulted by everyone in the family to get that adarsh bahu tag.
