new relationship

So I started a new relationship with this guy, we've been together officially for about a week. We fooled around before we became official. Yesterday I saw him on some other girls fb in her profile pic, and read some of the comments saying that she's beautiful as always baby and another comment saying that he he loves that black women and appreciates her and means a lot more than she thinks to him. Today he calls me saying I'm still waiting for you to add me on fb. And then he's like "listen thank you for everything your a really nice girl" like what exactly does that mean? He didn't say it was a breakup, but is it really? I literally never been so dumbfounded, he doesn't know I know about the girl.
