Should JaAn cut off from each other?Probably yes.
But is it possible given the equations they have with Singh family?Probably not.
So the onus lies on J and A themselves.
He still feels uncomfortable when He sees Anandi and Shiv together where as Anandi doesn't feel that way when she sees him with Ganga or for that matter Sanchi.
Anandi has completely moved on from Jagya. She doesn't see him as her husband any more.She just sees him as her childhood friend and has now come to a conclusion as they grew up they became lovers and got into a physical relationship as part of conditioning and it was passive acceptance of their relationship.She passively accepted him as her husband.She now realises that their relation was just an extension of their childhood friendship and that realisation happened with the help of Shiv.She now knows what a husband and wife relationship is all about and what marriage is all about.
She realised that the kind of relationship she and Jagya had is vastly different from the relationship she has with her husband.
She is also able to look back with out and pain or discomfort because she has no regrets about her past.She gave everything she had towards that relationship and yet it has failed.
On the other hand Jagya is still yet to find that partnership or companion.He declared his love for Ganga and Ganga also has accepted that she has feelings for him.But this has happened in the case of Jagya and Gauri relationship too.So time will tell whether Ganga will accept his attachment with Anandi and help him see the difference between that relationship and their relationship or not.So it is too early to say anything about Jagya Ganga relationship.
Jagya's case is more complicated because he carries burden of guilt from the past.At the back of his mind there will always be regrets about the way he handled things and the way he hurt Anandi. And also there is this constant comparison of his women with Anandi.The Singh Parivar does it and he too does it unconsciously most of the times.
Anandi has gotten over her Jagya phase completely but Jagya is yet to get over his Anandi phase till then they need to keep their interactions to a minimum.
