How People Fall In and Out of Love

I enjoy writing about a wide variety of topics that draw upon my decades of life experiences. I hope you enjoy reading my articles.

With modern analytical tools at their disposal, science has set its sights on how people fall into and out of love. Some of the findings have been quite unexpected and contrary to long held common beliefs regarding what love is and how people fall in love, stay in love, and in some cases fall out of love.

Interestingly, like much else in life, love between humans is very much a cyclical phenomenon, which is why human love can grow stronger and weaker over time. A fair characterization of human love is that there is actually a love cycle that occurs between two humans that are falling in love, are together as a couple in love, and in some cases fall out of love. The love cycle needs to be rejuvenated from time to time to avoid completing the cycle and falling out of love.

How People Fall Into Love

Scientific research using methods such as brain imaging and blood chemistry analysis has revealed that love between two humans is very much a chemical process that goes on in the bodies of each partner. Yes, what one thinks of the other person has a lot to do with falling in love. However, those overwhelming feelings of love when one is falling in love with another person are driven by a variety of chemicals that the body releases into the bloodstream that alter brain chemistry in a way to give one both feelings of elation and reduced capabilities for making sound decisions. It turns out that age-old term being “madly in love” is actually quite an accurate description of falling in love. In many ways, falling in love changes a person’s brain chemistry to a point where they may do things that their rational mind would never permit them to do; an altered state of consciousness bordering on madness. For lack of a better description, this initial stage of a loving relationship between two people could be called the blissful love stage.

Two chemicals are released into the bloodstream in large quantities and processed by the brain during the blissful love stage. Dopamine enters receptors in the brain that provide the blissful feeling of being in love. Norepinephrine provides something similar to an adrenaline rush when one is near the person they are in love with, which causes the heart to race and a general sense of excitement. Norepinephrine also causes people in the blissful love stage to be more oriented towards achieving goals and provides a heightened sense of attention, which provides two people in love the ability to focus on developing their new relationship and subsequently lose interest in other activities.

Another chemical change occurs in the human brain when people are in the blissful love stage of a relationship. Couples in love have serotonin deficiencies that are similar to deficiencies that people with obsessive-compulsive disorders have, which is likely why one obsesses over the object of their love. Brain imaging has found that the area of the brain that coordinates judgement, known as the frontal cortex, has vastly reduced activity when one is either near or shown a picture of the person they are in love with. This is believed to be one of the reasons why people go to great lengths to be with the one they love and sometimes make rash decisions that they would likely not make if they were not under the love spell. The reduction in frontal cortex activity also causes people in love to suspend doubts and critical thinking regarding their love partner, which is why many people have trouble seeing their love partner for who they really are during the blissful love stage.

The chemical nature of love is why people often fall in love with someone they are not necessarily intending to fall in love with. The love chemicals alter a person’s brain, and bam, cupid’s arrow has struck and a person is in love. Scientific research indicates that who one falls love with is also related to natural processes of finding a suitable mate for species survival. Men give off a barely discernible odor that attracts certain women who are unfamiliar with their odor, but repels women who are familiar with their odor. This is nature’s way of matching up genetically different people, as women are naturally repelled by similar smelling men, who in prehistoric times would likely be men that they were in close relations with (such as brothers or close cousins) that had very similar genetic makeups, which is bad for reproduction.

How Love Changes Over Time

The blissful love stage chemicals last for approximately two to three years, at which time their levels fall off and a new stage of the love cycle is entered, which could be called the mature love stage. It is at this point that a relationship enters a new venerable phase, and will endure if strong bonds have been made during the initial blissful love stage and efforts are made to rejuvenate the love from time to time. Besides losing much of the strong chemical reaction to the object of one’s love upon entering the mature love stage, one also regains their ability to think rationally about their love partner. This may introduce some uncomfortable thoughts, as faults that were overlooked while madly in love suddenly come to the fore. At this point in a relationship, some people claim their partner has changed, which may be the case, but it is also just as likely that one’s perception of their partner has changed, rather than an actual change in their partner.

This is why it is critical for couples to do things to rejuvenate their love from time to time. It is important to keep the love chemicals flowing and the feelings of love strong after the blissful love stage has passed. While a couple may never reenter the blissful love stage entirely, they can certainly do a lot to keep their love for each other going at a strong level to endure the unavoidable pitfalls and challenges that any loving relationship faces over time. This includes having intimate sexual moments on a regular basis, as sex releases a hormone called oxytocin that reinforces a long-term commitment between two partners. Endorphins are also released when couples have physical contact and sex, which makes people in the mature love stage feel secure and soothed when with their partner. Of course, there is a lot more to a lasting loving relationship than physical contact and sex. Good communication and just doing things together as a couple are also very important to keep a loving relationship strong in the mature love stage.

How People Fall Out Of Love

Unfortunately, some loving relationships do not continue in the mature love stage, and wind up reaching the end of the love cycle, which could be called the falling out of love stage. There are many reasons why people may fall out of love, from growing apart as people to losing intimacy and communication to finding other love interests. Whatever the reason for falling out of love, the brain chemicals that attracted a person to another person return to normal, leaving lingering thoughts and emotions in their place. The good news is that there is nothing stopping humans from going back into the blissful and mature love stages with another partner, or even rekindling their love with their original partner.

How to Cultivate Love

While falling in love has a lot to do with natural attraction and releases of chemicals in the body, there are ways that people can increase the chances of gaining the love of another person. While one cannot change their genetic makeup or directly cause the love chemicals to be released in the person one is hoping to make a mutually loving relationship with, there are ways to entice the release of such love chemicals in another person.

Interestingly, scientific research has shown that love chemicals are often released when two people endure a harrowing event together. It is not all that uncommon for two people to feel in love after experiencing a scary or dangerous event that they share. Of course, there is no need to have such an extreme experience with someone to develop reciprocal love.

The following are some ideas to increase the chances someone will fall in love with you.

  • If they visit the same place on a regular basis, just happen to drop by from time to time without being too obvious. If a relationship is showing signs of starting to cultivate, drop by more often, or suggest meeting up elsewhere.
  • Talk about some things that you have in common. It may provide for good conversation and put the object of your love at ease. It may also provide opportunities to meet up elsewhere and do something you both like to do together, which can start romantic feelings and love chemicals flowing.
  • Tell them that you like being around them, without being overbearing. People like to feel appreciated, not smothered.
  • Show sincere interest in what they do and what they like. Do not just talk about yourself. If someone is going to take a liking to you, show interest in them. Avoid awkward personal questions at the beginning, which could backfire and be conversation or relationship-enders. You will have plenty of chances to share intimate details of your lives, once a relationship has started.
  • Be positive and do not just talk about your problems. Everyone has problems. When you are trying to cultivate a relationship, it is important to have a positive attitude and check your problems at the door.
  • Give the object of your love a sincere compliment and make eye contact. People naturally love being complimented, and the eyes are the windows to the soul. What better way is there to connect to your love interest on a higher level?

Of course, sometimes love just is not going to happen, and it can be dangerous if one becomes obsessed with another person that does not have a love interest in them. If someone is not showing signs of falling in love, it is best to move on and find someone else that has better chemistry and is perhaps more inclined to fall in love, rather than obsessing over an impossible love. That can be hard to do since the feelings and chemicals associated with love are so powerful, but the best way to get over someone is to find someone else to fall in love with that has reciprocal love feelings.

Matthew Joseph from Nigeria on May 12, 2018:

Wow. This article has all the necessary information really. The chemical nature of love is really an eye opener. It kinda exposes how stupid we are, sometimes, all because we're being controlled by chemicals.

I'm glad I came across the vital piece of information.

Evane Go on July 27, 2016:

This is such a nice article! I love the section on cultivating love.

Suzie from Carson City on May 07, 2015:

Rock....glad this came around again. Just in time for me to make my announcement! I am a very "loving" kind of woman....affectionate, demonstrative, doting, smiley, huggie.....all of it.

However, speaking of "Romantic Love" .....the seeing stars & butterflies and all that gobbledeegook....anymore in my life, my brain is in complete & utter chemical LOCK DOWN.

Whatever romantic love meant to me at one time in my simply no longer lives on. Whatever it means to in joy, comfort, lust, passion, exciting, thrilling......enjoy it while you can. Trust me on this, you WILL get over it........LOL Awwww, don't cry. You won't miss it either. Ba-humbug.

Disillusioned from Kerala, India on September 11, 2014:

Ah! it looks the phenomenon of love, which is all along being thought as the works of the mind and heart, seems to get redefined as a 'dirty play' of some weird chemicals! Interesting!

By the way, if you inject such chemicals in a person (say one whom I love but does not reciprocate), will she turn favorable to me?!!


Ardhendu Dey from Jamshedpur on July 24, 2014:

Interesting hub. Liked very much.

John Coviello (author) from New Jersey on May 18, 2014:

Very interesting hub! Thank you for sharing. Voted up!

Suzie from Carson City on May 18, 2014:

Rock......A really terrific hub....."cycles of love." Based on who I am, my love of humor and my habit of using sarcasm, I want you to know the incredible "control" I am using refrain from printing some of the funny(albeit, Twisted) thoughts that went through my mind as I read!!

I respect your talent as an excellent writer and really appreciate the research and personal thought that went onto this hub, Rock.......

Therefore, fellow writer...I am remaining serious. LOL!

After all.....I understand falling in and out of love, just like the next girl and guy. Well, ..OK, maybe not the same.....maybe more, maybe less.

Then again Rock.....maybe "love" is the most confusing thing in the whole world??

You deserve a medal for tackling this!!..UP+++shared, pinned & tweeted.

Jane Ramona Rynkiewicz Frieman from Morris County, New Jersey on February 16, 2014:

Thank you for composing this heart felt hub regarding love. Your must have been Shakespeare in a previous life.

Tina Siuagan from Rizal, Philippines on October 27, 2013:

Another hub I can relate to. I've had a relationship which lasted for almost four years. Maybe, that aside from the chemical processes in my brain, there were other external factors that contributed to the break-up. I guess, the most important thing is that one does not stop loving. Love is a great feeling and I'm glad to have experienced the same in "various stages". Thank you for sharing... :)

Stephanie Henkel from USA on May 24, 2013:

I very much enjoyed your well-written article on the science behind falling in love. You've made what could have been boring science into an interesting and informative read. Voted up and shared with followers.

John Coviello (author) from New Jersey on April 19, 2013:

Thanks for the feedback everyone. I'm glad you found this hub to be interesting. It was a fascinating topic to research.

Gina from West Tennessee on April 18, 2013:

Good job on this hub. There are so many interesting points. I enjoyed reading it.

Ruchi Urvashi from Singapore on April 18, 2013:

Interesting information. Love is very important. The critical thing to remember is love is something we give. When we give, we receive. This can help couples who are falling out of love to regain a sense of control and bring back their relationship back to health and vitality.

Devika Primić from Dubrovnik, Croatia on April 18, 2013:

Most interesting about the love cycle, the reasons mentioned is so true and an you accomplished an excellent hub on this topic and glad to have read it makes me think about my love.
