My best friends boyfriend flirting with me?

[Kairii]

My best friend and this guy has been dating for a while now, and recently on Facebook her bf had messaged me asking do I know where my friend was at. (She had went out with her family for most of the day.) So, by the time I read his message, my friend was already home. So, I told him that she went out with her family and I had said im so sorry for the late response.😅
Then out of no where he said, "It's okay, I forgive you baby."
I kind of felt weird so I put "LOL" and then after that he asked me if I liked White guys (I'm black 😒) and I never responded to it. So, then the next day he was like "baby". I felt uncomfortable so I sent my friend a screenshot of this, and she's really pissed at him now. He keeps telling her she was joking and I have no sense of humor, but it wasn't funny to me and I don't even know him. Was I wrong for telling my friend? It honestly didn't feel like a joke to me.
