Does it ALL happen in her mind?

* SPOILER ALERT *

It doesn't take much knowledge of Freud to understand that the heroine of the film is trying to project the qualities of her late husband onto her new lover.

But I'd like to go a step further -- DOES HER LOVER REALLY EXIST ANYWHERE OTHER THAN IN HER MIND?

Some of the coincidences in the film cannot, I believe, be explained in any other manner. The fact that her husband wanted to move to Marseilles and that her lover, without any prompting on her part, also wants to move there, for the same reason (disgust with the cold, damp weather of Cologne); the fact that by total coincidence, the photo of her husband that she posts around the university reminds the lover's ex-girlfriend of a picture she took of him during a vacation, even the fact that at the end of the film, the heroine is shown, apparently happy and pregnant, in Marseille but with no hint that her lover is also there, the fact that her lover has just appeared to her in the penultimate scene with a daughter whose existence was never hinted at and who looks just like a girl at the party at the beginning of the film: all these can be explained only if we understand that the shock of her husband's death has caused her to imagine a replacement in her own mind.

Does anyone else feel the same?
