Bestfriend Boyfriend Clashing, What do I do when they don't like each other? Options

[ShimmyLovesYou]

So I've been going with this guy for about a month or so now, and I just got back from an incredibly long trip. Before I left I told him to try to get to know my bestfriend, because he wants to be together for a long time, so I think its important that they know each other. Well they talked for about a week before not talking anymore. I got back home and she basically said that she wants me to be careful around him, which I totally understood, and that she isn't too fond of him, which again I understood. So I was talking to him today and she came up and he said she was a bitch...which REALLY bothered me. I told him not to call her that in front of me, he asked if he could tell her that himself, and again I said no. He feels wronged by her (She tested him quite a bit while I was gone...she's my bestfriend so naturally she wanted to make sure he's a good guy...)

Anywho now I'm upset and I don't know how to handle the situation. I told him he's gonna have to get used to her but he basically brushed it off. I like him, but I don't like him calling my bestfriend something that she's not.

What do I do????

Well she told me up front when I got home, and when I talked to him about it he basically told me nothing, and so I only really have one account of the whole thing. But what she told me is totally believable for his behavior (He was planning out all this stuff before talking to me about it, she told him I wouldn't like that, and he got mad.) She's been pretty frank with him when it comes to me, because she knows me better than anybody. He's pretty pushy and he gets angry easily.
