I like how Nachiket has been shown to change, he is learning to be a father now. I am sure Ragini is still deep inside his heart but he is learning to keep the hurt inside himself. Maybe for him the best is to break all ties back in India as that will save not only him but also his kids from hurt.
Ragini is hurt as well and also dead from inside, maybe that is why it does not matter to her if she got engaged to Aman. In yesterdays episode, she did say she was a strict mother as that was the need of the time. She must now realize that her kids have grown up and they now need something more than strictness.
Ragini has her principles, and they are good, but she also needs to realize what her kids want and need.
In yesterdays epi, she told the truth to Nishi's inlaws right then and there, maybe it would have been better if she would have given Nishi a couple of days to inform her in-laws or waited for the next day gone over to their place and talked to them, instead of bringing out the matter in front of everybody.
She herself told a big lie about her fake marriage, continued that lie for 3 months and even involved other people to carry out the lie for her, and even in the end did not tell Nachiket the truth herself.
Nachiket does not seem to be bitter and does not keep blaming everything on Ragini, but on the other hand Ragini still seems to be bitter and keeps blaming everything on Nachiket. Kids do anything Nachiket Ka Khoon. Which should stop.
