@Anra7777 that he could do... If he was still alive.
I believe the guy said before that his will is in a safe.
Maybe he is already dead and a regent is ruling temporarily or just bedridden/sick and can't move a muscle or smth.
@WanderingKaos there's also the matter that killing your own father, if not creating a trouble of a crime, also creates rumour even if he diasappear as she is 'the one who
chased away/disappeared her father'.
Keeping in mind that their reality may be patriarchic, meaning women have less to talk, she may be just outright bullied by society wherever she goes even after divorce (if she avoids jail or other punishment).
Example: the recent case of sisters killing their tyrant "father" in russia and media trying to demonize them.
