REASON - The character did not cheat on her best friend by sleeping with her husband
It is very natural that two people fall out of love in marriages.. But you dont do such a thing with a pure soul like Mauli who helped nandini in all her problems..
A normal person will think a million times before you even start having feeling towards a guy who is your friends husband.. and here mauli is her best friend and always stood by her side..
Whatever be the feeling be.. Nandini had to stop herself..
Kunal is equally guilty, but he is still not so much a cringeworthy character.. he felt attracted to another woman due to his own reasons.. but nandini.. she could have done with anyone else..
Would nandini be okay if mauli and rajdeep were cheatingnon her.. even if rajdeep was a bad person and abusing her still she wouldnt be okay to this! So how dare she expect mauli to be accepting her and her fake friendship!!!
