For some people, a one-night stand doesn't make any difference in a seven-year love affair. I don't believe the degree of betrayal is always commensurate with the egregiousness of the behavior. They are two separate things.

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.

Modern infidelity is different than traditional infidelity and sits on top of the romantic ideal that you find "the one" and that if you have everything that you need at home, you have no reason to go looking elsewhere. And if you have an affair, it's a symptom of a flawed relationship. If you don't apply the deficiency model to the relationship, then you apply it to the person. The person who strays is selfish, immature, addicted suffers from insecure attachment. And the person who doesn't stray is the committed partner: mature, stable, and non-selfish.

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.

There is no neediness in desire ... there is no caretaking in desire. Caretaking is mightily loving, [but] it's a powerful anti-aphrodisiac.

Women want to talk first, connect first, then have sex. For men, sex is the connection. Sex is man's language of intimacy

The power of transgression is the archetypal, foundational story of the Bible. We want to break our own codes - sometimes of morality, sometimes of ethics, sometimes of the power structure, sometimes of the institution of marriage - because there is freedom and power in transgression.
