When Tanya didn't blame Sonakshi, who the hell is Rohit to blame, that too his own wife. Taali ek haath se thodi baj ti hai, how can he conveniently say that is Rastogi family's fault.
But honestly this is realistic, the fact that ruhit is siding with his family, every son dues that, unlike Rohit Sippy character till now, which was so unreal.
