Is There a Relationship Where We All Fall Out of Love?

I think what people fall in love with isn't just the other person but the promise of being someone else and someone better ourselves. I would say specifically the relationship I'm in now which I had not been in for very long when I may take this waltz. In Takers Waltz, Michelle Williams has the character that Michelle Williams plays so beautifully has quirks that she only shows her husband. She likes baby talk. They also have a really unique way of articulating their love for each other with sort of these profoundly violent, almost insults. It's heartbreaking when she tries to reenact this way of communicating with the man she leaves her husband for.
