Wat u say is right. Virat never said he loved someone else bt sai from the few conversations understood that he has someone spl in his life and when he said i hav promised someone else meant he was in love with sumone else.
Even when he said he is ready to marry her she said how vl u explain that to ur best friend?
Problem now is nt the vaada. Virat clearly said sai abt his vaada and nt to expect anything from this marriage. Bt he is the one who expects her to behav like a normal wife. Sai stood by the deal. She never came in btwn virat nd his friend. Never ask what he talks to her y he talks to her and why he supports her. Even she was ok with hia trip and pakhi asking his clothes so that she can pack in one bag.
She stood by the deal they made though she had that emotional torture a wife has. Though she feels jealous at times she doesnt display that. Bt on other side virat behave opposite to deal. He expects her to recognise wat he does fr her. He feels jealoys when she talks abt other boys. He feels insecured or ignored whenevr she talks abt the deal. Amongst all this may be inorder to keep her with him he is trying more bt end up hurting her.
And the most importnt part is after saying openly everything to sai. And pakhi openly claiming right over virat infront of sai and virat openly saying certain things infront of sai when pakhi left the house he now denies he loved pakhi once upon a time.
Not just sai even pakhi feela virat loved her and loves her that is why she asked with so much hope whether he loved her. When he denied she blamed him totally fr her loneliness.
Problm is nt with sai or pakhi its with virat. So it very tough to guess what wud the scenario be if their was no vaada. I guess it wud be similar becoz sai wud their past feelings and though marriage was a deal pakhi wud be the same and evrything wud be same. Its just that sai wudnt be able to say u said that u had a comittmnt not me. And pakhi wud be more villiany because no vaada means virat moving on which she wudnt be able to digest.
Other than this nothing wud much owing to itv standards.
