As per the current track I don't think there willbe any separation between Anant and Navya. Navya knows how much Anant will suffer without her. She will also never forgot the words of UB, BD. Her husband is insulted; my view is that she will to support Anant to make their life much more better.
Acc. To the story is Sugandha is not an educated woman, like all the India ladies mind her character is potrayed as she likes only the well being of her son, not taking into consideration her DIL 's pain. She is also suffering a lot with this life. Most of the MIL 's are like Sugandha only.
Like always UB, BD and Om plans will also result in failure until they realize that Love is important in life than their prestige and useless rules. Anant and Navya are having lots of respect to their elders, so in our story big ones have to realize their faults.
