I respect your point of view, and you are right as well, that they should have worked the other way, that should have ideally happened, had Kalyani been his first wife, or he hadn't been ditched and cheated in marriage. A person has deep trust issues and he is insecure, when earlier someone played with his softer side... He is reluctant in again showing his softer side completely to Kalyani. Let's consider that they hadn't fallen in love already to go though everything together and realise its importance. Back then, Kalyani and Malhar were working together because they were working against Sampada and Atharva, because he understood that Kalyani was not an ally with them. Right now he feels Kalyani is blindly supporting her mother,Despite the fact that she didn't do much to save her daughter and grandson's life... Kalyani anyway cares too less for her life,and that makes Malhar angry everytime. Right now also he is thinking the same, mere Biwi bachhe ki jaan ko khatra tha... That's nowhere about him. It's still about Kalyani and Moksh. And I am sure that no one who considers other a punching bag would fight the world, and even that person, to safeguard them. Do we still think she is not her apna?What " apna she is not a punching ball that he can use every time he is angry. They should have shown this track differently where they both together to find the truth rather than this way. That would have shown the development in their relationship.
