Advice needed!!

So I’ve been trying to decided on babies last name. I don’t want to give her mine (Misto) because my fathers a narcissistic asshole and I don’t want to continue that name so I’ve been thinking about giving her my mothers maiden name of Ryder. But last night my father called me mean names and said I’m immature for not wanting her to have the Misto name and said I need an intervention so I just need some advice on what I should do.
