Thank you for making this sensible post.
I think Raman is way off here and he will do a great injustice to the future of Adi by
succumbing to Shagun's emotional blackmail.
This is the worst message a Father can send an already spoilt and bratty kid.
This is a perfect opportunity for Raman to take Adi away from Shagun and and teach him Right from Wrong.
There should never have been this much dilemma for Raman if he thought with his head instead of love for a child and a woman that has made many mistakes and never paid for any of them.
For an otherwise smart man this is the first time Raman has put himself between a Rock and a Hard place. Between Right and Wrong.
If he supports Shagun and her emotional blackmail he will not only ruin his budding relationship with Ishita but ruin his son's future .
I do not know if Ishita will leave him, though I agree with you that there needs to be
a separation for both Raman and Ishita to come realize that there is a time to let go of the past and move towards a future that is based on sharing troubles and solving them by communicating not trying to hide behind guilt and the old age excuse of not hurting someone by keeping secrets.
Both Raman and Ishita are adults and should by now know what is the right thing to do and what is not.
I am hoping Rama's instincts of what is good for his son in the long run kicks in and he does the right thing.
