No logic

I don't understand how this leap makes any sense. If Pragya and Abhi blame each other for Kiara death l, then how can they be ok with one daughter each? Especially Pragya. If she believes that she should have never brought Kiara to Abhi and that Abhi is a bad father, then how in the world is she ok with leaving one daughter with him? And, on top of that, why would they each not want to be in both their daughters lives? Why would anyone break ties where there is no contact? Abhi should be paying child support at the least. This is total BS.
