It is impossible to end a relationship.
It is only possible to change it.
This is probably the most important understanding anyone could come to when beginning a relationship. All relationships are never-ending. It not a question of whether we are going to have the relationship but of what kind of relationship we are going to have.
Our relationship with another goes on and on and on. Even if we never see another person again, we have a relationship with them. And the nature of that relationship affects the days and times of our lives in a very real way.
