Is he wrong for allowing his daughter to disrespect me?

So I was seeing this guy and we were going through some stuff and at the time I was really hurt pregnant and emotional so I said some stuff on facebook, his daughter seen it and told him so a few weeks later he asks me to call his daughter so I do and she gets a disrespectful and calls me a b word and we go back and forth and I hung up, so I told my boyfriend what happened and he immediately defended her and justified her calling me out my name saying well she’s pregnant as well but what about me I’ve never done anything to disrespect her and if she didn’t want to talk to me she could have not answered or told me not to call her anymore.
