It took me forty years of marriage to understand that I’d been asking the wrong questions about love.

For decades, I watched how my husband acted on our anniversaries, during romantic dinners, when life was sailing along smoothly.

But the real education came during a particularly brutal winter when I had the flu, our car died, and his mother needed emergency surgery all in the same week. That’s when I finally saw what genuine love actually looks like.

The inconvenient truth about real love

Most of us spend our younger years measuring love by its highlights. The surprise flowers, the passionate declarations, the grand gestures. We frame these moments and hold them up as proof. But here’s what nobody tells you when you’re 25 and dizzy with romance: those moments are easy. They’re fun. They come with built-in rewards like seeing your partner’s face light up or feeling that rush of being adored.

The real test happens at 2 AM when you’re both exhausted and the baby won’t stop crying. Or when work is crushing you both and there’s nothing left to give but somehow, you find something anyway. Kathy McCoy, Ph.D., puts it perfectly: “Love means showing up and caring about another in challenging as well as good times.”

I remember one Thursday evening about fifteen years ago. I’d had oral surgery that morning and was miserable, swollen, unable to talk. My husband had worked a twelve-hour day and had an important presentation the next morning. I watched him come through the door, exhausted, and without a word, he went straight to the kitchen to make me soup. Not from a can, but the homemade kind that takes an hour. He sat with me while I sipped it through a straw, reading me funny stories from the newspaper because he knew I needed distraction more than sympathy.

That’s love. Not because it was dramatic or Instagram-worthy, but because there was absolutely nothing in it for him except taking care of me when I needed it most.

When exhaustion reveals everything

You want to know someone’s true character? Watch them when they’re running on empty. Exhaustion strips away our carefully constructed personas and shows what’s underneath. The same goes for love.

I’ve noticed something over the years about the marriages that last versus the ones that don’t. The lasting ones aren’t filled with people who never get tired or stressed or overwhelmed. They’re filled with people who treat their partner well even when they are all those things. Mark Travers, Ph.D., notes that genuine partners “stay regulated even when you’re not.”

This doesn’t mean being a saint. We all snap occasionally, say things we don’t mean when we’re worn down. But there’s a difference between human imperfection and a pattern of only showing up when you’re at your best.

My husband and I nearly separated in our early fifties. We were both exhausted from careers that had consumed us, facing retirement with completely different visions of what came next. The conversations were hard, sometimes harsh. But even in our worst moments, when we could barely stand to be in the same room, he still left the porch light on for me when I worked late. Still filled my car with gas without being asked. Those small acts of care, maintained even when we were struggling, told me everything I needed to know about whether we could work through it.

The nothing-to-gain moments

Here’s something it took me too long to figure out: genuine love shows itself most clearly when there’s absolutely no benefit to the person giving it. No audience to impress, no immediate gratification, no quid pro quo.

Think about it. Anyone can be charming on a first date when they’re trying to win you over. Anyone can be attentive when they want something. But what about when you’re sick with something unglamorous and contagious? When you’re grieving and need the same conversation for the hundredth time? When supporting your dreams means sacrificing theirs?

I watched my husband turn down a promotion that would have meant relocating just as I was finally building my career. He never once threw it in my face during arguments. Never kept a running tally of what he’d given up. He made a choice to prioritize our life together, and he owned that choice completely.

These unglamorous moments of choice, repeated over and over, build the foundation of lasting love. They’re not the moments you tell stories about at parties, but they’re the ones that matter when you’re 73 and looking back at a life built together.

Why it takes us so long to learn

I wish I could go back and tell my younger self to stop keeping score of the flowers and fancy dinners and start paying attention to who shows up when showing up is hard. But maybe this is one of those lessons that only comes with time and experience.

When you’re young, you’re still learning who you are, much less how to recognize authentic love in someone else. You mistake intensity for depth, passion for commitment. You think love should always feel good, not understanding that sometimes love feels like work because it is work.

It’s only after you’ve weathered some storms that you start to value the person who holds the umbrella steady more than the one who only shows up for sunny days. Only after you’ve been genuinely exhausted yourself do you understand what it costs someone to show up for you when they have nothing left.

A new way to measure

If you’re reading this and recognizing that you’ve been measuring love by the wrong metrics, you’re not alone. Most of us do it for longer than we’d like to admit. But it’s never too late to start paying attention to what really matters.

Watch how someone treats you when they’re stressed about work. Notice whether they follow through on small promises when no one’s watching. Pay attention to how they respond when your needs inconvenience their plans.

And perhaps most importantly, hold yourself to the same standard. Real love isn’t just about finding someone who shows up for you when it’s hard. It’s about being that person too.

The truth about lasting love

After 45 years of marriage, countless conversations with friends navigating their own relationships, and probably more mistakes than I can count, here’s what I know for sure: the clearest sign someone genuinely loves you has nothing to do with how they act when they’re trying to impress you.

It’s how they act when they’re tired and you need them anyway. When supporting you costs them something. When loving you is inconvenient and they choose to do it anyway, not with resentment or scorekeeping, but with the quiet steadiness of someone who’s exactly where they want to be.

Those of us who’ve been around long enough to see marriages rise and fall, to watch love tested by time and circumstance, we all eventually come to the same conclusion. The only version of love that matters is the one that shows up when showing up is hard. Everything else is just romance, and romance, while lovely, won’t sustain you through a lifetime.

Look for the person who fills your gas tank without being asked, who makes you soup when they’re exhausted, who chooses you even when choosing you costs them something. That’s the love that lasts. That’s the love worth building a life on.
