Adi and Imlie are flawed characters that have made mistakes through out the story. But I have started seeing Adi more wrong since the moment he started brushing aside Imlie’s concerns regarding Malini, even after he was raped he chose to trust AC (because that doesn’t tarnish the image of Malini that he has) over Imlie, after that also he lets AC comes to his house and insults Imlie and he remains silent, why? After Malini accused Imlie and told him to his face that only she or his wife can stay in his house, he is still blindly trusting her, not even realizing the power she thinks she has over him and his relation to his wife. Imlie left home because of Malini’s influence on him and he doesn’t say anything when Malini behaves as his wife at his house. 
The moment Adi saw Imlie smiling at Aryan, Malini’s words about his wife became golden and set in stone and he thinks that she is going away from him and towards Aryan.
Even in Imlie’s difficult conversation she mentions that when boss-intern relation is misunderstood then it is difficult and still he is accusing her of her relation with Aryan.
I didn’t want to mention this and offend people so didn’t mention it in my earlier post. Today, I just couldn’t shake this feeling that Adi finally realized what he is asking of Imlie when Rupi had put herself in Imlie’s position and asked him, “will you make your sister do the same thing.” I think more than anything, that is what made him open his eyes.
