A lie is a lie no matter what.
But then, I won't lie when I will say that I myself have recourse to White lies some times, like you said, sweet lies, to keep one's heart or more to escape from Mom's scoldings *Yea Mom, I did sleep early or of course I have been revising only and did not touch my mac at all*😆
But here, what Aarti is doing is a completely different thing.
She is hiding things concerning HIS child to Yash and the whole family.
The lie about her wedding was something she herself didn't want and wanted to tell it all to Yash. But here, she is giving in to the demands of the Dubeys as if the lies won't ever come out.
I truly am of view that Yash SHOULD have been made aware of all. I don;t believe that Yash is someone who would have preferred letting Prashanth die rather than given his consent for the BMT.
She is getting herself entangled into a vicious circle of lies day by day. Earlier I had hope that Yash would have forgiven her. But now it's getting worst. Like they say, Jhoot pe jhoot, till when will this go on. Does she not trust Yash enough to share her problems and dilemma.
Yash gonna be hurt big time on knowing it all, especially if he will know it from a third party and this time am not gonna blame him if he turns into HULK once again 😆
