Was this film satire?
I think it was a good film but I found the whole, "this is normal in France and my culture" a bit weird, knowing France and French culture isn't like this.
So it made me think the whole thing was satirical of being and wanting to be something that isn't really what it is presented as, like wine being an acquired taste when most of the world drink it to get drunk or doing so many things just to part of something.
Which is why the whole separating himself from it all was delivered with a slap, be a part of our world or get out. She got trapped in the world and stayed with it, obsessiveness with Guggenheim and it's nearness to Central Park, and the surrounding wealth of that area.
I just felt it was making fun of people desperately trying to be something they are not. The whole thing being encompassed by desperately trying to appear married but breaking every rule of marriage - a mockery of modern day perspectives of open pseudo-closed relationships.
