My best friend hates my husband

D • Mama of 2,lost an angel, waiting on number 4💘💓💘 married-blessed💓
I had a little fight with my husband and got pretty angry so I told my best friend. 
She was like immadiently saying that he's a dick and a bastard and he doesnt deserve me and that she hates him and wants us to seperate and stuff like that and she said he's no good for me and changed me and that really hurt me.
I mean I did fight with him but I love him to death and she hates him. She's like my sister and he always helped her with everything.
So basically she texted him saying he was a prick and bastard and asshole and so on and he was like "I'm not talking about that with you, thats a thing between my wife and me" and then she came to me saying he was super rude.
I love them both so much and I dont want them to fight- at least not her because he really didnt say anything rude, compared to what she said to him. 
I told her to apologize but she doesnt want to and is acting all childish. I don't know what to do.
