To a frustrated single person, life can often feel like this:

And at first glance, research seems to back this up, suggesting that married people are on average happier than single people and much happier than divorced people. But a closer analysis reveals that if you split up “married people” into two groups based on marriage quality, “people in self-assessed poor marriages are fairly miserable, and much less happy than unmarried people, and people in self-assessed good marriages are even more happy than the literature reports.” In other words, here’s what’s happening in reality:

Dissatisfied single people should actually consider themselves in a neutral, fairly hopeful position, compared to what their situation could be. A single person who would like to find a great relationship is one step away from it, with their to-do list reading, “1) Find a great relationship.” People in unhappy relationships, on the other hand, are three leaps away, with a to-do list of “1) Go through a soul-crushing break-up. 2) Emotionally recover. 3) Find a great relationship.” Not as bad when you look at it that way, right?

All the research on how vastly happiness varies between happy and unhappy marriages makes perfect sense, of course. It’s your life partner.

Thinking about how overwhelmingly important it is to pick the right life partner is like thinking about how huge the universe really is or how terrifying death really is—it’s too intense to internalize the reality of it, so we just don’t think about it that hard and remain in slight denial about the magnitude of the situation.

But unlike death and the universe’s size, picking a life partner is fully in your control, so it’s critical to make yourself entirely clear on how big a deal the decision really is and to thoroughly analyze the most important factors in making it.

So how big a deal is it?

Well, start by subtracting your age from 90. If you live a long life, that’s about the number of years you’re going to spend with your current or future life partner, give or take a few.

(Sure, people get divorced, but you don’t think you will. A recent study shows that 86% of young people assume their current or future marriage will be forever, and I doubt older people feel much differently. So we’ll proceed under that assumption.)

And when you choose a life partner, you’re choosing a lot of things, including your parenting partner and someone who will deeply influence your children, your eating companion for about 20,000 meals, your travel companion for about 100 vacations, your primary leisure time and retirement friend, your career therapist, and someone whose day you’ll hear about 18,000 times.

Intense shit.

So given that this is by far the most important thing in life to get right, how is it possible that so many good, smart, otherwise-logical people end up choosing a life partnership that leaves them dissatisfied and unhappy?

Well as it turns out, there are a bunch of factors working against us:

People tend to be bad at knowing what they want from a relationship

Studies have shown people to be generally bad, when single, at predicting what later turn out to be their actual relationship preferences. One study found that speed daters questioned about their relationship preferences usually prove themselves wrong just minutes later with what they show to prefer in the actual event.

This shouldn’t be a surprise—in life, you usually don’t get good at something until you’ve done it a bunch of times. Unfortunately, not many people have a chance to be in more than a few, if any, serious relationships before they make their big decision. There’s just not enough time. And given that a person’s partnership persona and relationship needs are often quite different from the way they are as a single person, it’s hard as a single person to really know what you want or need from a relationship.

Society has it all wrong and gives us terrible advice

Society encourages us to stay uneducated and let romance be our guide.

If you’re running a business, conventional wisdom states that you’re a much more effective business owner if you study business in school, create well thought-out business plans, and analyze your business’s performance diligently. This is logical, because that’s the way you proceed when you want to do something well and minimize mistakes.

But if someone went to school to learn about how to pick a life partner and take part in a healthy relationship, if they charted out a detailed plan of action to find one, and if they kept their progress organized rigorously in a spreadsheet, society says they’re A) an over-rational robot, B) way too concerned about this, and C) a huge weirdo.

No, when it comes to dating, society frowns upon thinking too much about it, instead opting for things like relying on fate, going with your gut, and hoping for the best. If a business owner took society’s dating advice for her business, she’d probably fail, and if she succeeded, it would be partially due to good luck—and that’s how society wants us to approach dating.

Society places a stigma on intelligently expanding our search for potential partners.

In a study on what governs our dating choices more, our preferences or our current opportunities, opportunities wins hands down—our dating choices are “98% a response…to market conditions and just 2% immutable desires. Proposals to date tall, short, fat, thin, professional, clerical, educated, uneducated people are all more than nine-tenths governed by what’s on offer that night.”

In other words, people end up picking from whatever pool of options they have, no matter how poorly matched they might be to those candidates. The obvious conclusion to draw here is that outside of serious socialites, everyone looking for a life partner should be doing a lot of online dating, speed dating, and other systems created to broaden the candidate pool in an intelligent way.

But good old society frowns upon that, and people are often still timid to say they met their spouse on a dating site. The respectable way to meet a life partner is by dumb luck, by bumping into them randomly or being introduced to them from within your little pool. Fortunately, this stigma is diminishing with time, but that it’s there at all is a reflection of how illogical the socially accepted dating rulebook is.

Society rushes us.

In our world, the major rule is to get married before you’re too old—and “too old” varies from 25 – 35, depending on where you live. The rule should be “whatever you do, don’t marry the wrong person,” but society frowns much more upon a 37-year-old single person than it does an unhappily married 37-year-old with two children. It makes no sense—the former is one step away from a happy marriage, while the latter must either settle for permanent unhappiness or endure a messy divorce just to catch up to where the single person is.

Our biology is doing us no favors

Human biology evolved a long time ago and doesn’t understand the concept of having a deep connection with a life partner for 50 years.

When we start seeing someone and feel the slightest twinge of excitement, our biology gets into “okay let’s do this” mode and bombards us with chemicals designed to get us to mate (lust), fall in love (the Honeymoon Phase), and then commit for the long run (attachment). Our brains can usually override this process if we’re just not that into someone, but for all those middle ground cases where the right move is probably to move on and find something better, we often succumb to the chemical roller coaster and end up getting engaged.

Biological clocks are a bitch.

For a woman who wants to have biological children with her husband, she has one very real limitation in play, which is the need to pick the right life partner by forty, give or take. This is just a shitty fact and makes an already hard process one notch more stressful. Still, if it were me, I’d rather adopt children with the right life partner than have biological children with the wrong one.

So when you take a bunch of people who aren’t that good at knowing what they want in a relationship, surround them with a society that tells them they have to find a life partner but that they should under-think, under-explore, and hurry up, and combine that with biology that drugs us as we try to figure it out and promises to stop producing children before too long, what do you get?

A frenzy of big decisions for bad reasons and a lot of people messing up the most important decision of their life. Let’s take a look at some of the common types of people who fall victim to all of this and end up in unhappy relationships:

Overly romantic Ronald

Overly Romantic Ronald’s downfall is believing that love is enough reason on its own to marry someone. Romance can be a great part of a relationship, and love is a key ingredient in a happy marriage, but without a bunch of other important things, it’s simply not enough.

The overly romantic person repeatedly ignores the little voice that tries to speak up when he and his girlfriend are fighting constantly or when he seems to feel much worse about himself these days than he used to before the relationship, shutting the voice down with thoughts like “Everything happens for a reason and the way we met couldn’t have just been coincidence” and “I’m totally in love with her, and that’s all that matters”—once an overly romantic person believes he’s found his soul mate, he stops questioning things, and he’ll hang onto that belief all the way through his 50 years of unhappy marriage.

Fear-driven Frida

Fear is one of the worst possible decision-makers when it comes to picking the right life partner. Unfortunately, the way society is set up, fear starts infecting all kinds of otherwise-rational people, sometimes as early as the mid-twenties. The types of fear our society (and parents, and friends) inflict upon us—fear of being the last single friend, fear of being an older parent, sometimes just fear of being judged or talked about—are the types that lead us to settle for a not-so-great partnership. The irony is that the only rational fear we should feel is the fear of spending the latter two thirds of life unhappily, with the wrong person—the exact fate the fear-driven people risk because they’re trying to be risk-averse.

Externally-influenced Ed

Externally-Influenced Ed lets other people play way too big a part in the life partner decision. The choosing of a life partner is deeply personal, enormously complicated, different for everyone, and almost impossible to understand from the outside, no matter how well you know someone. As such, other people’s opinions and preferences really have no place getting involved, other than an extreme case involving mistreatment or abuse.

The saddest example of this is someone breaking up with a person who would have been the right life partner because of external disapproval or a factor the chooser doesn’t actually care about (religion is a common one) but feels compelled to stick to for the sake of family insistence or expectations.

It can also happen the opposite way, where everyone in someone’s life is thrilled with his relationship because it looks great from the outside, and even though it’s not actually that great from the inside, Ed listens to others over his own gut and ties the knot.

Shallow Sharon

Shallow Sharon is more concerned with the on-paper description of her life partner than the inner personality beneath it. There are a bunch of boxes that she needs to have checked—things like his height, job prestige, wealth-level, accomplishments, or maybe a novelty item like being foreign or having a specific talent.

Everyone has certain on-paper boxes they’d like checked, but a strongly ego-driven person prioritizes appearances and résumés above even the quality of her connection with her potential life partner when weighing things.

If you want a fun new term, a significant other whom you suspect was chosen more because of the boxes they checked than for their personality underneath is a “scan-tron boyfriend” or a “scan-tron wife,” etc.—because they correctly fill out all the bubbles. I’ve gotten some good mileage out of that one.

Selfish Stanley

The selfish come in three, sometimes-overlapping varieties:

The “my way or the highway” type

This person cannot handle sacrifice or compromise. She believes her needs and desires and opinions are simply more important than her partner’s, and she needs to get her way in almost any big decision. In the end, she doesn’t want a legitimate partnership, she wants to keep her single life and have someone there to keep her company.

This person inevitably ends up with at best a super easy-going person, and at worst, a pushover with a self-esteem issue, and sacrifices a chance to be part of a team of equals, almost certainly limiting the potential quality of her marriage.

The main character

The Main Character’s tragic flaw is being massively self-absorbed. He wants a life partner who serves as both his therapist and biggest admirer, but is mostly uninterested in returning either favor. Each night, he and his partner discuss their days, but 90% of the discussion centers around his day—after all, he’s the main character of the relationship. The issue for him is that by being incapable of tearing himself away from his personal world, he ends up with a sidekick as his life partner, which makes for a pretty boring 50 years.

The needs-driven

Everyone has needs, and everyone likes those needs to be met, but problems arise when the meeting of needs—she cooks for me, he’ll be a great father, she’ll make a great wife, he’s rich, she keeps me organized, he’s great in bed—becomes the main grounds for choosing someone as a life partner. Those listed things are all great perks, but that’s all they are—perks. And after a year of marriage, when the needs-driven person is now totally accustomed to having her needs met and it’s no longer exciting, there better be a lot more good parts of the relationship she’s chosen or she’s in for a dull ride.

The main reason most of the above types end up in unhappy relationships is that they’re consumed by a motivating force that doesn’t take into account the reality of what a life partnership is and what makes it a happy thing.

So what makes a happy life partnership? We’ll explore in
