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.

As a teenager growing up in Europe, I embraced the romantic ideal. For me, I had to give up the ideal that one person would be there for everything. Once you give up that ideal, then you begin to accept the person that you are with - the person who won't be able to give you everything and who won't be able to know exactly what you want and feel without you even needing to say it.

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

Today, monogamy is one person at a time.

Love is at once an affirmation and a transcendence of who we are.

The meaning of secrecy is very different when the model of love is one of transparency. So to understand the politics of secrecy and revelation, you need to understand the larger culture in which the couple lives and also the culture of the couple itself. What does intimacy mean to them? Where does the couple draw the line between togetherness and separateness? That's what informs you. You always ask, "What would happen if I tell? What would happen if I don't tell?" Sometimes, the partner doesn't want to know.

The very ingredients that nurture love - mutuality, reciprocity, protection, worry, responsibility for the other - are sometimes the very ingredients that stifle desire.
