Asmi, again, much of what you are saying here goes back to his inability to look at situations from other people's perspectives- be it Sai or Pakhi...he gets engulfed in his own emotions, and his intentions have always been pure, so he has been unable to look past that. This has taken a deep toll on Sai, as this is the exact reason why he has not clarified anything to her- because in his mind, it should be crystal clear and there is no need to do so in the first place. All of these moments that you have mentioned between Virat and Pakhi- I agree were uncomfortable... but, again, I don't think it's fair to say that these were signs of an emotional affair nor relationship, because that implies that Virat was intentionally being disloyal to Sai...and to me, his commitment and dedication to Sai has never waivered.
See Pooja, like in above post quoting Nethraa I have mentioned, I dont call it intentional, but does not mean he was not. If I look at it being in that place, I see it as borderline emotional affair/relationship, unintentionally. There was no point him justifying things that he did to Pakhi , w.r.t. Sai. There are a lot of studies going on Emotional Affair that happens at all work places without people realising it is that, while they are it.. They call it friendship, while thats not the case..Has been very prominent one in the metro cities. I was amused to read the book , when I came across certain aspects of that relationship...I keep saying it was unintentional, but it was there. That's how underrated emotional affair is , because one does not realise it at all..
Plus like I say when you make certain waadas in such clear words, they need to be cleared in the same spasht words..But then thats another topic.
