Well, yes. I did write few on them. And I believe fictions are self explanatory as to why it should not be hidden.
A woman who believes that trust/faith on the partner as the main factor in a marriage is now totally unaware of where her husband goes and what he does. I know they wouldn't show her POV in the show. But if Om just tells her a word about it and asks her to stay calm, she definitely would do so.
A woman is in a position where her husband royally ignores her, disappears out of blue without telling the reason and is kept in the dark whereas on the other hand, she keeps thinking about him, gets worried for him and keeps thinking about his family. And may be sometimes she keeps thinking about what is bothering him so much. Obviously when such a big plan is made, at some point a husband's emotions comes infront of his wife which would make her concerned. This I believe is not shown in the show.
Provided that they have come a long way from misunderstandings to trusting each other, If he can't even trust her with family issues, then the very base of the relationship is shook again. And that woman would definitely feel that she has been cheated all the while
It's not the insecurity, it all comes down to trust again.
Well keeping in mind all these emotions which are never shown, fictions are based.
This is entirely my POV. I'm not replying further.
And those fictions were also based on the fact that they have butchered Gauri's character beyond measure.
