There are complaints about the ending. But I found it to be a happy one. There were a lot of clues about the art dealer's true motivations. He found Maria charming, yes. But his true motivation was to meet her supposedly aristocratic family in Madrid and make some lucrative sales. He was no different than the other shallow, unfaithful, mercenary characters in that social set. She escaped the ultimate fate of Anne and the other chronically cuckolded characters with her dignity intact. And the knowledge of Maria's integrity and character, along with the expression on her face, made her appear truly beautiful as she crossed that bridge - despite her oddball features.
