Ridz has been doing things out of duty nature. That is, she does things because she thinks she should do it that way. This trait is inbuilt in her character. This is the way she has been doing things from the beginning of her marriage. This exactly is the reason that Sid was furious with Ridz in the beginning of the marriage. Remember he said, rather shouted in his famous testing event after holi (I am sorry I cant write in Hindi), "I thought I will bring home a wife. I never thought I will bring home a doll. That is what you have become Ridhima". It is exactly this behavior of Ridz that added fuel to his other frustrations (like having to marry a girl who consumed poison just before wedding). Even in spite of all his frustrations he tried his best to make her see the point and was indeed successful.
Slowly with time, she started becoming normal (the progression can be seen from honeymoon time onwards), that is a human being again. She started responding to the situations instead of behaving like a doll. And then, we can see that Sid also started responding to her positively and in fact started liking her, then loving her etc. This progression was really shown beautifully and there was no step back to this till the time she met Arman in Pune. During this period, in fact both of them progressed towards each other, deriving support from each other and is indeed beautiful.
I can now understand Sidz frustration (post lonavala incident) and dilemma (pre lonavala incident and post Arman in Pune). Because after Arman, Ridz is back to square one. Yes, I can now clearly see that she is back to the spot where she has started her journey as a wife. Yes exactly, she has retraced. She wants to be loyal to Sid and hence all her mechanical behavior. And we can see Sid noticing her behavior and reading between her lines (like marriage is everything for me, you are my aaj etc). Those were the lines recited by a doll or a tape recorder (by chance the name of the tape recorder is Ridhima). I think this time, Sid is really frustrated and has probably given up.
Today we really a saw a beautiful scene between Arman and Ridhima. This time Arman is making her realize the point. Indeed she herself started realizing the point to a small extent in her thoughts while she was waiting at the doorsteps of her house "Probably I am not doing things 100%".
Hopefully, this time, Ridhima understands this completely and will never go back to doll mode in future. Any person should show their frustration if they are frustrated. They should try to be as much natural as possible at least in front of the persons with whom they have to deal maximum amount of time.
PS : The only thing that is of little disappointment for me is, "important relationships should derive its strength from the persons involved in the relationship itself, but never from an outsider". When a relationship is broken, an outsider giving support is good (example, Sid supporting ridz w.r.t to Arman). But the same should not apply for making a relationship (example, Arman making Ridz realizing Sidz importance).
