according to me any person in his shoes cannot judge and take a decision easily on who is right and who is wrong.. I am really glad that he neither trusted Gauarv blindly (at least on what he said about their relation) and supported him , in which case he would have blasted Sidhi nor he completely took Sidhi's side and blasted gaurav for speaking nonsense..
I also loved the fact that he did not confront Sidhi in front of Gaurav or in front of the family, however upset and angry he was on her, he still respected their relationship,and i feel it is the best way to deal .If a husband does not show respect and trust in his wife, no one else in the family will ,so by keeping quite he sent the right signal to the family members that he is still with her and by trying to protect her he also made sure that she is not completely left alone or feel insecure.lHad he shouted on Sidhi in front of everyone, Gaurav would have definitely taken advantage of the situation sooner or later . , .
Normally in EK serials we see the woman taking the centre stage as main protognist , as main vamp, ..etc etc..so ideally in these kind of situation the mother , MIL or the elder woman of the family would have taken the control of the situation so I am glad when situation was going out of control, Raj stepped in and took control , and the way he pointed out finger on Kunal was also worth a praise..at least Cvs should be praised for upholding the male centric theme of the serial.
