The part I find most interesting is she had a husband who was not surprised
But I wanted to say was sometimes its social isolation that does those things; I knew a girl, well i knew her for maybe 2 or 3 months who sometime ago murdered her uncle (I was never around or in touch with her since those 2 or 3 months) and the weird thing was she would've gotten away with it if she hadn't felt guilty about it and confessed.
I would not say she was princessed at all, spoiled and isolated, maybe; she was the only child her parents would just leave at home all the time, but she was never princessed, she just did not seem that way.
