It was Raima who was a fake friend to Sakshi. She deceived her all these years though Sakshi helped her often and defended her from Jatin too.
But no sympathy for Sakshi as she chose this life herself. She deceived Rehmat. Raj and Raima deceived her. She deceived the world for Shaurya. Shaurya deceived her.
She gets hurt but that hurt is self invited.
She actually is a proud woman who needs to share her exploits to a fawning but meek audience that Raima projected herself as. In plain words, she needs chamchas!
Nothing hurts her except her kids. Though she did cry at being deceived by RajMa.
I wonder why she didn't react much when she learnt that Shaurya knew of the RajMa affair?
Maybe they need to bring it up again and show her that selfie with bedsheet clad Raima in Shaurya's phone!
I don't think merely his lies can crush her. She's too forgiving for him. She needs to lose Shaurya or get violently spurned by him to get a jolt.
Though I do not endorse it, but I guess she deserves what Aruna Irani's son did to her in Beta. I am sorry for proposing such an idea but I feel only this can truly shake her.
