Being called the N word

Caitlyn

a very long story follows this, but long story short; my friends boyfriend hates me for decisions that I have made in the past that have nothing to do with him. She mentioned me to him over text a few days ago and he called me “another filthy fucking ni**er.” I’m at a loss for words because I’ve never been called anything that had to do with my race. My mom is half black half white and my dad is white. My friend did not defend me in any way and just said “he’s an ass.” At first I just laughed it off but I keep thinking about the comment and I’m not sure how to react. It makes me sad and angry. I never thought I would be called that in my life. I’m even more upset she did not defend me. I’m really just at a loss for words of how ignorant people are🙂
