nandini is never selfish, if she is selfish she would be with karan now..She didn't answer to tanya, she is unfit to even talk to her & she think she is her best friend to her even now also, taking her husband & child.. if u remmeber r or karan wants divorcee from tanya,if nandini wants karan & droling she would have got karan that time only, why she had to do a fake marriage natak, only to help tanya, & realise that tanya is now.. u see the differeent, after tulsi nandini is the best character in kyunki..tanya nature is that when she sees tulsi with nandini, or tulsi talks with nandini she feels that tulsi mar jaye,kyon ayi hai, Is it a bahu say to her mother-in-law that too infornt of her son?????nandini ab bhi tulsi ko respect kar thi hi???? Tanya should realise that she is only living in sn now nandini ki yehasan se,..how could u live 20 years with a man who says u r only my best friend?????
If u want only children tho, mahir also had karan with mandira,he also meet mandira behind tulsi..he is also a man...wo bhi tulsi is there alive not in coma like that...tanya got pregnant when nandini is in coma, karan visits hospital frequently & when he is sad. tanya that time says that don't worry nandini will come back from coma like that comfornts him,so there r weak moments, emotional moments that too they r wife & husband that time.. after leap it showed clearly that everynight karan will comes lately, means he doesn't love her even though she is with him, my point why she is living in a shameless life??? she didn't have self-respect???
