Honestly, based on how the Dad was shown after having to get divorced, getting rejected by the public, and then your daughter says they hate you and your passion (even if she didn't mean it), I wouldn't necessarily "fault" him for deciding "enough is enough" and ending it.
It's sad to think she'll never have the chance to apologize, but she DOES have a chance to right that wrong by showing the world how great her dad's characters really were.
