You could inform your dad that if he believes it is important to abuse and exile you for making adult decisions, you believe it is important to share your personal story of emotional, parental, and religious abuse with the police, media, and newspapers out of concern for the protection of other youths, including any you her siblings at risk by them. Additionally, inform him that you will file a report for harassment against him if he attempts to communicate overstep again as his actions make you feel legitimately threatened.

He will fold. Narcissists are punk bitches.

(I understand this is extreme; yes, I did these things. Yes, they work.)
