That's the whole point of leap Kri..From every perspective the end result is the same...Ishita is nothing without a kid..One way or other everyone proved it except Ruhi..Sad but true...
That's what's proven to herself & so every action she will interpret that way.
She herself had value to Raman sans kids pre-leap especially in bhoot & jail track whether she realized or not.
But I will also propose the same applies idea applies to Raman and Shagun. Ishita married Raman bc he was Ruhi's father & she is going back and playing house with someone for the sake of the kid. Shagun also is being treated like trash honestly by Raman but she is around bc of Pihu. Shagun lost all value when Adi turned & same will happen for Pihu. Regardless of their ability to bear a child or not - at face value post-leap these 3 characters only have value out of what they do for kids. None are happy nor are they living
This importance of a person without the kid applies to them all.
But I disagree with you about this track's point. It is to break this thought for Ishita like guilt track was to make Raman realize he wasn't a failure...this is for Ishita to see she is more than a mother. It is for Ruhi and Raman "to realize her value" and bring her back - not just to take care of the kids.
