Agree.
She's only 19 and has taken a lot from him and still kept supporting him... dunno many women her age who'd be able to do it.
At the same time, this marriage and how it happened in the beginning has messed her up big time... Malhars life philosophy of handing out punishments anytime he feels someone did wrong has affected her so badly,that the girl now spontaneously asks to be punished anytime she thinks she did something bad: this is not healthy behavior,especially not for someone her age.
And she has believed in him more than she did in anyone else,yet he has mostly doubted her and only trusted her when it comes to Moksh.
She's allowed to be hurt that someone she's put so much trust into, didn't reciprocate the same way and broke her trust.
Their relationship begun as one of convenience and revenge due to Moksh and Mallu wanting to avenge the wrongs he felt were done to him by all the Deshmukhs by marrying and then torturing Kalyani,yet she has never blamed or thrown any of it in his face... but that doesn't mean all of that didn't hurt any less,she just buried it deep inside and it comes out in the form of actions such as her hiding these informations,because a part of her is afraid he won't trust her or break her trust,even though in this case we know Malhar has good reasons to be concerned and do what he did.
And I keep seeing people talking about Kalyani putting Pillu and Anu before Malhar.
Well... a while back,Malhar was the same way regarding his work.
Yet,I remember in the initial phases of their marriage she did some hella crazy things to help him out of situations,like when he accepted an accusation of rape from Atharva's secretary because he was being blackmailed by someone who had Godavari's fake dirty pics or when she moved heaven and earth to prove him innocent of the accusations of being behind her own grandfather's suicide... yet,in the latter he still misunderstood her.
When you do so much for someone and that someone still keeps showing lack of faith in you,it does end up affecting you someway.
