I am new here.
Was watching the episodes now.
In the episode when Sai comes to Virat house in Garchiroli to ask him not to marry her. During the conversation, Sai asks about Pakhi. And the moment she takes Pakhis name virat remembers his vada to P that he will not love anyone and he says it loud.
It looked looks he is saying it to himself here ans reminding himself that vada. Maybe he has already started liking Sai and this was assurance to himself.
Even Sai, if not love him now, she respects him. She was also indirectly asking nd understaning his relation with P and what he feels for her.
And the whole conversation after that was both trying to assure themselves reather than each other
