Anjali already knows her hubby is a creep. She has been living with him for so many years, so of course she must know there is something wrong. Remember when Mamiji told her about him signing divorce papers, she did not want to hear it. Even if Shyam himself confesses the truth to Anjali she still wont accept it. The problem is Anjali's need to create a perfect world around her even if it is fake. I think Arhi should have her consult a psychologist rather than look for evidence against Shyam, Because no matter how strong the evidence it will not convince Anji.
