Loneliness in two.
Sometimes life in the couple can be difficult. Although somehow linked to feelings or social rules, "contractors" are subject to a variety of real or imagined reasons. It has happened to us many times in life to feel a sense of frustration, beacause although together, declarative or even legal, we wake up alone in front of it, as if each of us would pull in another direction.
A road, two directions, desirable convergent but unfortunately in the present case, diverging.
