My older sister left home at 17 and never returned. I did the same.
Daughters do appreciate it when their parents protect them, when they let them know that they are priceless and worthy of protection. You do this from the cradle, so they don't feel a need to find affection in the arms of a male at 15.
Daughters also like to feel safe. When dad's finished taking his anger out on boyfriend, will she be next? If dad can't control his temper in public, will he in private?
We can “what if?” anything to death. There’s nothing to indicate Dad is abusive to his daughter, to the contrary he is protective of her. I’m sorry you grew up with events in your house to cause you to leave at age 17. That doesn’t happen to everyone.
Your Daddy may have just been a mean SOB. I had a Granddaddy like that, or so my Daddy told me. There was nothing in the story about him having gone home and been abusive to the daughter; I’d think that would have been covered, because SOMEONE would know about it!
This isn't about a father beating his son or daughter. You are setting up a straw man. I doubt very seriously if this father will beat his daughter. My father-in- law did just what this father did, beat the crap out of a man that had sex with his 16 yo daughter, he never touched his daughter, the man was the one he was pissed at. Keep flailing your tongue you might hit on something that makes sense eventually.
