That's what abhi-pragya are. Their ego, their fights, their pain means more to them than their children's happiness.
Today for the first time prachi showed pragya that she wanted to know and meet her father by expressing that she feels that the man who had an accident and for whom pragya is showing so much concern is her father. Prachi desperately wanted an answer.
What justification does pragya have as a mother to keep her child away from knowing about her father? Is her father a dangerous criminal? No! Is he a bad and evil man? No! So why keep prachi away from knowing about her father even when she asks without having any solid reasons to keep her child away from her own father?
The answer to that is ego! Her and abhi had a fight, now she wants to stay away from him and she wants to punish her daughter whilst she's at it.
The icing on the cake in terms of pragya's selfishness was her double-standard stance on suicide. Prachi can't attempt suicide even if her life is being made hell by someone just because it would hurt pragya, but pragya can hurt prachi by threatening suicide merely for prachi asking about her father, despite it being prachi's right?
