You'd let a girl friend disrespect your mom? Doesn't surprise me
No. But he's right to some degree
If a crazy gets a hold of your teenage kid you have to stay the adult. You're the parent. You can't expect they'll pick you over someone they're sleeping with. You can't give ultimatums. Hopefully you raise your kids well enough that they respect you. I was raised to respect my parents. We don't cuss, drink or even think about anything inappropriate in their almighty presence lol
But I went through that phase too.
