I mean, both of them are wrong... But his wife really did neglect the shit out of him, so I can understand why he started getting more involved with people who actually seemed interested in what he had to say, especially when his own wife clearly didn't care much about those things.
But at the same time... he became a fucking horrible person. Both of them are awful for neglecting their daughter and for what they did later. Both. But her father, dude... I wanted to punch the shit out of that asshole. Like, she was nothing to him? SERIOUSLY? I can somewhat understand him being bitter toward his wife, but his own daughter? Nah. I really hope he got fucked over.
And her mother projecting the shit out of her own failures onto her own daughter is also absurd. She has absolutely no right to act like she's somehow above all this and in the right. Control narcisistic freak.
Thanks for the translation and for the final notes! <3
