Young couple goes on van tour of US, boy comes back with van - no girl

So I saw this in the NY Post, so who knows how true it is, although they give it as a quote. To be very, very clear, I am not victim blaming and I quite literally would not wish the pain of losing a child on the worst person in the world. But it kinda makes you wonder about a few things.

I don’t have daughters so I have no clue how to raise a daughter to maximize her self-esteem in order to equip her to tell a controlling boyfriend to hit the bricks. But this doesn’t seem like an optimal approach:

“ Gabby Petito’s dad says he had a mocking nickname for his daughter’s boyfriend, Brian Laundrie, who is now a “person of interest’’ in her disappearance-turned-suspected death case.

Joseph Petito revealed that he’d refer to Brian as “Brianne,” according an episode of “Dr. Phil” that aired Monday.

“I’ve never actually liked any of Gabby’s boyfriends. I’ve never actually called any of them by their real name, ever,” said the dad, who is originally from Long Island.

“I always tried to use the female versions of the boyfriends’ names, just to intimidate them a little bit,” he said.

“They laughed,” Joseph Petito said. “Although as the years progressed, I think [Gabby] prepared them for when they met me.’’”
I think you have to know your child. Really know your child.
My oldest is 18 youngest 13 and I know, certain things, I can only go so far or start to erode at her self esteem.
And neither are same things. Each is different. What may start as playful banter can quickly change and I've learned that over the years. Was he truly dialed in? Don't know. But as a father, it's imperative you learn these little things because it shapes their views as they become young adult women.

I know this much, my daughter ain't driving cross country with a guy she recently broke off engagement with and both exhibiting some mental instability.
