Why did you fall in love?

A woman with long hair, adorned with a floral headband, smiles brightly at a man facing her. The scene is outdoors with a soft, golden sunlight in the background, creating a warm and romantic atmosphere.

Love is a wonderful, largely inexplicable thing, and we can’t be logical all the time. That wouldn’t be any fun at all.

Sometimes, we just have to feel, not think, and not try to rationalize everything.

But understanding the reasons why you feel the way you do can help keep your feet on the ground.

It can help you appreciate why it feels like the world is ending when you lose a romantic love, or like you couldn’t live without the object of your affections.

It can also help you to gain clarity on exactly what it is you want out of a romantic relationship, and take control of your hormones, recognizing who really would make the perfect partner for you in the long term.

Understanding the reasons why human beings, as a species, fall in love can help you figure out the role love plays for you, personally.

If you’ve been searching for some insight into why you feel the way you do, read on for a few explanations.

1. As our bodies evolved, our ability to love developed.

A smiling couple leans close to each other, their faces almost touching. The woman has long blonde hair, wears a white sleeveless top, and gold earrings. The man, with dark hair and a beard, is in a salmon-colored shirt. Both look very happy. The background is softly lit.

It’s widely agreed that it’s our ability to love one another, or develop strong pair bonds, that has made us such a successful species.

In case you hadn’t noticed, human beings have dominated our beautiful planet, for better or worse.

We human beings have very large brains inside very large, thick skulls.

But, to be very reductive about it, when we came down from the trees onto the African savannah and started walking on two feet, our pelvises changed shape and became smaller.

That, in turn, meant that women needed to give birth to smaller, less developed babies in order to live to tell the tale and nourish those babies to adulthood, so the species continued to thrive.

Compare them with the young of other mammals and you’ll get a good idea of just how helpless a human baby is when it’s only been cooking in its mother’s tummy for a mere nine months.

A newborn giraffe is running around within hours, able to flee from danger and feed from its mother, but a human baby needs years and years of devoted love, care, and protection to survive.

That means that human babies are more likely to survive if they’ve got two parents to care for them, rather than just one.

Love is what keeps those parents together and motivates them to commit and hang around even when things get tough, as they inevitably will.

The love we feel for our partners, as well as for our children, is what forges family units and means we work together to raise children and ensure they make it to adulthood.

I know it doesn’t sound romantic, but most people agree that the love we’re capable of feeling for one another is a huge part of why human beings have been so successful.

2. Those big brains mean we can feel big emotions.

A woman with blonde hair and a colorful scarf looks lovingly into the eyes of a man wearing glasses, a gray hoodie, and a brown vest. They are outdoors, with autumn leaves blurred in the background, creating a warm, romantic setting.

Out of all the animals on planet Earth, we have the largest brains.

And it seems that those brains mean we’re capable of overpowering emotions.

We’re all about extremes.

We’ve got the most advanced language skills around, and we’re also far more likely that any other mammal to kill one another, as uncomfortable a thought as that might be.

The point is, it’s been argued that, as a species, we’re prone to going all out when it comes to our emotions.

We don’t do things by halves. We’ve evolved to be capable of extreme hate, and passionate love.

That might play a big role in why we’re able to form partnerships that can last a lifetime, and can feel like we’d do anything for love.

3. It’s all down to hormones.

A couple embraces on a sunny beach. The woman with short hair smiles with her eyes closed, wearing a striped shirt. The man with a beard kisses her on the cheek, wearing a gray sweatshirt. The background shows sandy beach and blurred cityscape.

Okay, so I’ll admit that chalking love entirely up to hormones isn’t exactly the most romantic of concepts, just as attributing it all to evolution and reproduction isn’t the stuff that Valentine’s Day cards are made of.

None of us really wants to accept that the way we feel about the person we want to spend the rest of our lives with is all down to hormones, now do we?

On the other hand, when you’re going through the pain of a breakup, the idea that it’s just withdrawal from the hormones your brain released when you were around that person can be quite a comforting one.

But without wanting to ruin the magic of it all, long term, committed love is characterized by two hormones: oxytocin and vasopressin.

They’re warm, fuzzy hormones that motivate us to form a long-term bond with a romantic partner.

If you’re trying to get over someone, reminding yourself that love is essentially all about hormones which will eventually start to leave your system can help you see light at the end of the tunnel.

4. We want company.

An elderly couple sits on a bench under a tree, looking up and smiling. Both are casually dressed; the woman wears a dark jacket and jeans, while the man has on a blue denim shirt and khaki pants. Behind them, there's a colorful wooden building and greenery.

Human beings are naturally sociable creatures, and whilst many of us enjoy being on our own now and again, most of us have a need to seek out the company of other human beings.

A romantic partner is someone you can go through life with. Someone you know is always going to be there for you. Someone you can talk to, have adventures with, and cuddle up to.

5. We need support.

A couple with tattoos cuddles on a couch covered by a gray blanket. The woman with short pink hair is resting her head on the man's chest, who has a beard and short hair. They appear relaxed, surrounded by a cozy living room setting with soft lighting.

If we’re lucky, we’ll have a strong support network of friends and family to rely on.

But there’s nothing quite like the support of a romantic partner.

A partner or spouse is someone you can rely upon through thick and thin. The right relationship can give you the security and support you need to spread your wings and fly.

6. We crave affection.

A young couple stands in a shaded area, with the man embracing the woman from behind. The woman smiles gently, holding his hands, while the man looks at her affectionately. Both are casually dressed in dark clothing, and the background is blurred with pillars.

Okay, so we’re kinda getting back to hormones here.

Physical contact with other human beings releases feel-good hormones that fill us with a sense of contentment.

A romantic partner can give us the physical affection we crave.

7. We think about the practicalities.

A man with wavy blonde hair wearing a green jacket and a white shirt smiles at a woman with long blonde hair wearing a black jacket and a white shirt. They are outside, with blurred buildings in the background.

This is another very unromantic one, but our desire to be in a relationship with someone and the love we feel for them can sometimes be motivated, in part, by practical considerations.

After all, a problem shared is a problem halved.

Having a romantic partner in your life often makes sense financially, and normally makes things like child-rearing and running a household far easier to handle.

Don’t underestimate the power that practicalities can have when it comes to romantic attachment.
