Young black female talking to an OLDER white male..NEED ADVICE??!?

So, I have been talking to this older guy who I am really interested in. He is really cool, BESIDES the fact he always talks about in a vile manner with me. I mean, when our conversation is good, its good...but when he goes on his raves it is VERY bad...it's disgusting some of the things he says. I am a young black female and he is a middle aged white male. I met him while at work, and I think he only talks to me to divulge in his fantasy of being with a black woman since he told me he never has. What should I do??
