(A hat tip to a friend who suggested this subject and title but had only examples of horribly Unsafe Ex illustrating what to avoid but not what to practice.)
As the highest form of animal life on the planet, we ought to wonder why no species performs worse than we do at ending relationships. In our evolution, have our relationships become too complex for us to handle? Have our pairings evolved (devolved?) beyond our natural capacity to manage them? If so, we ought to do one of two things: improve the quality of our relationships (our general and ordinary preoccupation) or master the fine art of becoming an Ex, which is the subject of this post.
