Two questions I have about ending that can't be answered.

Did Juliet actually leave Georgio? I think yes. It makes sense but it's not certain.

How did Georgio react if/when he realized Juliet had left him? Did he marry the girlfriend or dump her? I think the latter; he seemed to be getting a thrill out of the taboo aspect of the affair in a similar way as other Fellini philanderers.

I think Georgio would have been devastated.
