mom called me a hoe

My mom knows that I struggle with insecurities and dysthymia and all of these other mental issues. And I've gotten well with most male friends at school so much so I dated 2 of them, the one who cheated on me and the other who keeps Sending me "graphic pictures" (both are ex's) and she constantly makes unsubtle comments on why my ex boyfriend cheated on me in public and to anyone she can gossip to. 

But I drew the line when She went out of her way to call me a hoe when I showed her a picture of me and my boyfriend in a clearly healthy and happy relationship in church after the service while they were serving cinnamon rolls I showed her a picture of us cuddling together, When she shouted out 

"You fucking hoe." 

And when we sat down at the table after a brief prayer she said

 "if you keep hoeing yourself around and showing off your body to men I'm not going to be the one to take care of you when you get pregnant." 

I'm still not talking to her, because of this and she's trying to get me to talk to her. What can I do?
