There was no love from Kabir's side for sure...but to say Riddhima never loved him would be wrong. A girl cant be so crazy as to sacrifice her life, dignity, etc for a man she doesnt "truly" love.
Also one correction. Riddhima never seemed to be in any major conflict about Vansh. She blindly trusted Kabir and was convinced that Vansh is a murderer even after Dadi told her the truth. It was only after seeing Ragini's photo with her parents and matching it with Satte's appearance that she had seen on video call that she realized, there is more than what meets the eye.
Regarding Riansh, their romance is being built beautifully. Vansh provides Riddhima with the security that she needed all along subconsciously but never realized before. Especially after hichki, jhoomar, pool scene, it is natural for a girl to have second thoughts.
My only peeve is...so much cannot happen in just a week! Even if it does...it shouldnt wipe off the memory of the other guy from Riddhima's mind completely for whom she married Vansh in the first place! More a glitch on the part of the writers than Riddhima herself! They needed to make it look like the shootout happened a month or two ago at least.
I'm going on the basis of having only watched 4 or 5 episodes 😆and a few RiAnsh scenes. My theory might be all haphazard but what I gathered of RidhBir from Ridhima's side - if Kabir had pursued and led her along to use for this mission - then it's natural her feeling of being 'needed' were fulfilled through this. Yes she will have developed feelings but if Ridhima could take bullet for Vansh not knowing her feelings then why would it be suprising that she'd help Kabir in this way. That's Ridhima's persona so far.
I agree about the glitch of the writer's. But considering it's a thriller we don't know where the cv's will use what track to turn the story around.
