I guess I get it

What it's like for a Parisian woman of a certain age to go through her dating life, especially when she is not that good at reading people.

And it all ends up [spoiler] in despair with a fortune teller. [/spoiler]

Wonder that she does not try online dating. Actually, that's the curious trick of the film. It never shows us how she meets the various guys or how the relationships develop. The script assumes we already know all that. And I suppose that we do. Movie watchers have seen so many thousands of "meet cutes" before. But that is also what we tend to like about such stories. If the writers take that away, they have to put in something intriguing instead, but am not sure they really found such a thing to put in here.
