Agree about your point that Minnie has fooled her father too. This is exactly what NB was referring to when she asked HS how much he really understood Minnie, to which his response was that she was brave, strong, etc. There's a whole side to her that he hasn't seen.
I don't think he accused her of planting that CD or that he genuinely did not trust her, because if that is the case then it is wrong. He asked her how it got there but did not pursue that line of questioning, so I am assuming his doubts were cleared. Let's see. But his feeling hurt was based on the realization (or so he thinks) that she doesn't want him, and I think he is right to feel that way based on the information he currently has. In future, when he finds out the truth - and I really hope this time Khatri is caught - then he needs to take a step back and assess why he was so quick to think Minnie was the one to do this, rather than ask Babita why she still held on to that CD.
babita having the CD could just have been a miss. maybe babita and mini never realised it was there and babita only realised when the CD was played, that it was still among her things.
@Bold 1 - he did not pursue his questioning but sometimes even 1 question is enough to break things
@Bold 2 - he may be right to feel the way he is feeling, but to not even let mini speak? to physically stop her from going to her babes? babita maybe his wife, he may consider babita his wife without the ceremonies, but he has no right to stop a child from going to the mother. no one does. not even a biological father, not even God.
@Bold 3 - maybe because he never addressed how hurt he was, maybe he should have spoken to mini.
just personal opinions. no offense meant.
