Affairs can be powerful detonators. They can invigorate a marriage that's flat, jolt people out of years of complacency. Fear of loss rekindles desire, makes people have conversations they haven't had in years, takes them out of their contrived illusion of safety.

Most affairs do die a natural death. Today, you look at your partner's phone to find out the weather, and you find out about a lover. It has never been as easy to cheat as it is today, and it has never been harder to keep a secret.

On some level we trade passion for security, that's trading one illusion for another. It's a matter of degree. We can't live in constant fear, but we can't live without any. The fear of loss is essential to love.

Even a good marriage leaves people with longings for certain things their marriage will never be. So, do they accept that, make compromises, and say, "You can't have everything in life," which is what we always did? Or do they say, "I deserve more. I want to experience that thing and, you know, I have fifty more years to live than I used to." It's not necessarily that we have more desires today, but we do feel more entitled to pursue them. We live in this "right to happiness" culture, and yes, we do live half a century longer than we used to.

One of the big misconceptions is that affairs or trysts are flings about sex. And sometimes they are, but much more often they are about desire. And that is very different. The desire to feel special, to feel seen, to feel appreciated, to be laughed at or with. The desire to be desired. That does not manifest in a sexual act per se. Affairs make you feel alive. Alchemy means it's not about the actual sex, but the sexuality, the energy, the aura. It's the imagination and anticipation of it as much or instead of the actual experience of it.

People cheat on each other in a hundred different ways: indifference, emotional neglect, contempt, lack of respect, years of refusal of intimacy. Cheating doesn't begin to describe the ways that people let each other down.
