Very good points and I can definitely see that. Yeah, and it seems that they all forget Catherine was once a stripper and turned her life around. You just can't judge a book by it's cover. But in the end Ellen was bad news anyway and Nick was probably thrilled to some point that she was because he knew it would not last between Greg and her. But I can see Greg eventually going back to Nick for comfort since he was pretty hurt by how the whole thing turned out.
