They BOTH take mauli for granted and don't see that nobody in this world can give them the love and support they need but they both keep looking from others.
Nandini is too desperate to have a man in her life to even appreciate her best friend's unconditionally supportive and loving nature. For nandini, she has no goals, no aspirations, but just the desire to have a man who will baby her and worship her like his queen. That's all she wants, and doesn't see mauli's love, support or her feelings past her own selfish desire for a loving partner, that she stole mauli's partner, and somehow she seems to feel that not mauli, but kunal is her ultimate saviour, you know, because for her she doesn't need, want or see a saviour as a woman, but sees her saviour only in a man who gives her even a smidge amount of attention. #
She sees only kunal and nobody else as the one to have helped her by saving her from kunal, because he is a man, and a man's help clearly means more to desperate nandini than the help of anyone else. She now has turned all her affection towards the one man she thinks can fill the void in her life, and sees nothing past him, and calls it love. But this is the second time that nandini has failed to see mauli is the one she can trust the most, who will support her more than anyone, but mauli doesn't have the "manly weapons" for nandini to be able to see her as the person who loves her most in the world. That can only be a man who is willing to bed her.
Kunal is on a whole new different level of desperate and ungrateful. Even he took the fact that mauli is the most loving, supporting and understanding woman he could ever have in his life, and instead went looking outside the relationship to look for a girl who makes him feel more manly and who would be more than willing to spend the rest of her life running to his beck and call, having no job other than to deck up for him and pleasure him. Bloody creep. Both these losers are desperate and need a reality check.
