I agree this way they are loosing more and more viewers and looks like thy don't even care.I don't understand why Nahar isn't confronting Saloni with what he saw and what has pissed him off so badly. He could easily explode on her with what he saw.... i think the only reason why the writers are doing this is so that they can drag the story further more. Nahar mad at Saloni isn't too good if dragged more and more.
Thias is not realistic either. When one suspects one confronts rahter than putting it off. Nahar has put this off long enough. he is also hiding from Saloni that he suspects devika is chandani. This will hurt their relation more.
