I just started watching the show from episode 1 and have got to the mid October episodes.
All mother's love their kids unconditionally - and so does Rajyashri Rathore but unlike most moms, Rajyashri never observed her son's personal traits through the years.
I am not saying that his deviant personality is a result of her poor nurturing. But she has certainly strengthened it by ignoring all the red flags that her intuition would have raised.
He lies. He hurts. He is self-obsessed. He is incredibly superficially charming but leaves a truly awful amount of emotional and physical destruction behind him. These traits did not develop overnight - they were there in his youth and perhaps childhood. Why does Rajyashri not have an inkling of their existence? Why is his sister, Meera, unaware too?
Now (that is, until mid-October episodes), his fiance Vidhita is being conned by him. She is so inexperienced - that she has no clue what she is getting into by marrying him.
Yes, Pushkar has a major personality problem. His mother has a veil over her eyes. It is symbolic - that prior to the wedding the introductory scene of the episodes showed Pushkar pulling a veil over Vidhita's eyes and right after the marriage Vidhita is shown without a veil. Soon, she will realize that she has married a person with a major personality disorder!!
