Another fabulous post.
But I feel we both have different views and if you could not see what am trying to say then we must agree to disagree.
Lot of things are going on my mind now so I just hope I can place my perspective properly without confusing the readers much.
I completely agree with you on Yash's stand point in Pari's matter.
The only similarity Pari and Aarthi hold is they both are hiding truth(s) about them to their respective partners. Other than that I think the circumstances that led to both their decisions are not comparable (atleast to me).
But if we are going to compare Pari and Aarthi then I feel both their decisions are out of their personal choice only. We cannot keep on blaming the other people and situations for our so called actions. Somewhere we have to take a stand and be brave to face the reactions for our actions. The only difference I see Aarthi got enough chances to confess to Yash whereas Paridi is yet t face any such situation which could force her to confess to Prateek. If we say Aarthi has lots of 'majboori' in revealing the truths in the fear of losing Yash then I could very well see Paridi's majboori in hiding the truth in the fear of losing Prateek.
Hope I made sense.
Right now, could not explain my points in detail due to time constraint. If possible, later I'll try to update here or in any DC if am writing a take.
