lol this falling in and out of love with the same person really makes no sense to me 😆..but as it's a fictional show they can write anything they want..Also is kunals love so weak...that it can break , then mend again then break again,,lol😆. Anyway seriously speaking for some betrayed wives or husbands ..if their spouse has cheated ..it's enough for them to end the marriage completely even if the spouse wants to come back to them...some people just can't stand betrayal and cheating ...but I suppose they are going to show it differently here in Silsila...kunu going back to mauli was always on cards...the hints were given in the epi itself...its how you look at it and crack...there was always slight hints given of kunu falling in love with mauli back and realise his mistake
if nandini was alive...she would have been insecure and would have trust issues in their relationship...furthermore mishti would have been the link for her insecurities and of course their medical profession...both are doctors...destiny will bring them together and kunu realise what he missed from his life...which lacks in his current life...he will be drawn towards mauli and fall in love with her...this insecurities would have made nandini on gtey shades
