For the following films, its not so formulaic.
These almost relationships are heartbreaking and yet very relatable.
Theyll always have Tokyo.

Up In The Air (2009)
But Jesse receives some pretty grownup news that almost destroys the entirety of their relationship.
The game of emotions that ensues finds Celeste and Jesse struggling to figure out where they stand.
Thus, they end up becoming stagnant rather than growing.

It works effortlessly at first, with the two complimenting each other well, but then it falls flat.
It seems to work in his favor, until things begin to crumble for some unexplained, inexplicable reason.
Instead, the romance factor actually stems from Ricks sacrifice and the fact that the couple cant get together.

Blue Valentine
Tragically selfless, yes, but also truthful and still utterly romantic.
