@Kagamimocchi If I remember it right, Vio's mom was just REALLY persistent and clingy to the point her father just gave up and cave in (that's IF I remember it right. Plus, there was also the fact the mother is politically stronger/had a higher status *in the ln, it will be a plot point later, heck, I'm not even sure if it was already implied but Vio is naturally the one who will inherit her mother's title, not her father which is also 1 of the reasons why the father hates her*). He tried to love her but you know its hard to love someone crazy and obsessive. Her obsession just became worse when he left to pursue someone sane and he could love. Now, does it justify his actions for abandoning Vio and mentally/verbally abuse her because she looks like her mom? Of course not.
