Someone’s Finally Explained Why Lust & Love Fade

Why do feelings of lust never seem to remain? Why does love fade to routine? These are our pathways of passion; learn more and change your romantic destiny.


We all know the crazy things we do when we’re “in lust” and the total preoccupation of being “in love.”

Some of us also know the joyful satisfaction of growing older with the “love of your life.” But how do you write about it? I started with a Google search of quotes about “love, lust, and happiness.” 

Here are a few that resonate for me about these pathways of passion:

“Sheet ripping, sweat dripping, loud screaming, legs trembling, hair pulling, ass smacking. Now you’re talking.”  —Anonymous

“Falling in love is like getting hit by a truck and yet not being mortally wounded, just sick to your stomach, high one minute, low the next. Starving hungry but unable to eat. Hot, cold, forever horny, full of hope and enthusiasm, with momentary depressions that wipe you out.”  —Jackie Collins

“Love never claims, it ever gives.”  —Mahatma Gandhi

“First best is falling in love. Second best is being in love. Least best is falling out of love. But any of it is better than never having been in love.”  —Maya Angelou

Helen Fisher, Ph.D. may know more about these various aspects of love than anyone on the planet. She is a biological anthropologist and has written five books on the evolution and future of human sex, love, and marriage. She and her colleagues have studied gender differences in the brain and how our personality type shapes who we are and who we love.

She is also a Senior Research Fellow at The Kinsey Institute and Chief Scientific Advisor at Match.com.

When we fall in love, get married, start a family, and work through the ups and downs of creating a life together over the years, we don’t think much about how our brain functions. However, Fisher has found that human beings have three primary brain systems related to love:

Lust Brain System

This system evolved to get us interested in sexual intercourse so that we would be magnetically drawn to potential sexual partners. “I think the sex drive evolved,” says Fisher, “to get you out there looking for anything at all. We lust to ‘get it on’.”

The Falling in Love System

When we fall in love with that “special person,” we are euphoric. We think only of them, we are ecstatic in their presence and bereft when they are away. The craving is intense and if we lose our lover we are devastated. Romantic love, she thinks, developed to focus one’s mating energy on just one individual. When we’re “in love,” we only have eyes for our partner. That’s a good state to be in to conceive a child.

This euphoric feeling is not meant to last. We wouldn’t make good parents, or be able to be very productive at our jobs, if we maintained this obsessive, driven, roller-coaster state of mind for many years.

The Attachment-Life System

Unlike most other species of mammals, human children need years of care. This brain system focuses our attention on creating a stable partner bond so that we can create a close attachment between the parents and the child. In this way, the child can survive and thrive long enough to grow up to start the process of lust, love, and life once again.

Understanding how our brains are wired can help us come to peace with certain realities of being human:

Evolution & Our Mis-matched Brains

It’s important to remember that our brains evolved hundreds of thousands of years ago to insure our survival during the time we were hunter-gatherers on the savannas of Africa. Many of the problems we have today are because of modern mismatches. During our evolutionary past, we lived in small groups of 150 people. Our choices for mates were limited. Our choices for infidelity were limited.

Now there are so many choices available, we lust after millions of people in a big city and an infinite number of attractive people on-line. Our choices for partners with whom we can cheat are also unlimited. Further, our social support systems are breaking down so maintaining a stable group of people who can help support a long-term committed relationship becomes more and more difficult.

Advice for Those Who Want it All

Some people settle for lots of lusty sex, but never commit to one person. Others make a commitment to one, but lose sexual desire over time. They tell me “I love him/her, but I miss being ‘in love.'” Some have it all for a while, but then something goes wrong. They wonder if it’s worth going through the process again.

For those who want to have it all I offer the following suggestions:

Wherever you are in your life—married and happy, in a committed relationship that is struggling, or single and looking again for love—get some help sorting it all out. Most of us never learned about how to integrate lust, love, and life. It’s never too late to learn.
