There is a woman I know, call her Adaeze, who loves her husband the way a well-tended fire loves the wood it is given: completely, warmly, without holding back.

For nine years, she has woken up before dawn to see him off, absorbed his bad days without complaint, buried her own opinions to keep the peace, and told herself that this is what love looks like.

Then one evening, she sat across from me, hollow-eyed, and asked a question that undid me: “Why do I feel like I have nothing left to give him, when I have given him everything?”

I want to sit with that question for the length of this piece, because I think it holds one of the most quietly controversial truths about love: you cannot love another person beyond the capacity at which you love yourself.

Not because love is selfish. Because love, like water, cannot rise higher than its source.

What Love Actually Is (And Why It Isn’t Care)

We throw the word “love” around Nigerian households and church halls until it loses its shape. But love and care are not twins; they are cousins who look alike from a distance.

Care is a function: it feeds, it clothes, it shows up, it manages. You can care for a stranger, a patient, an aging parent you barely know, out of duty alone. Love is different. Love is a posture of the whole self toward another self, wanting their flourishing as much as it wants its own, and it does this without being asked.

Care can be performed. Love has to be inhabited.

This is where many of us, especially in cultures that prize sacrifice as the highest proof of devotion, get confused. We mistake the exhaustion of caretaking for the depth of love. Adaeze wasn’t short on care. She was short on self, the very thing love is supposed to be made of.

“You cannot pour from an empty cup. You can only pour from the surplus of what you already have.”

The Arithmetic Nobody Teaches Us

Here is the uncomfortable arithmetic: if your relationship with yourself is running a deficit, if you neglect your body, silence your own needs, tolerate a mind you haven’t made peace with, or live inside surroundings that drain rather than restore you, then whatever love you offer another person is being borrowed, not given.

Borrowed love has interest. It shows up later as resentment, as quiet withdrawal, as the sudden coldness that baffles the person on the receiving end who swears “nothing changed.” Something changed. The lender ran out of reserve.

This is why self-love cannot be the shallow, Instagram-caption version we’ve reduced it to, bubble baths and treating yourself to suya on a Friday. Real self-love is structural. It means loving your body enough to rest it and move it.

Loving your mind enough to face what troubles it instead of numbing it. Loving your friendships enough to prune the ones that cost more than they give. Loving your physical space enough to keep it in a state that doesn’t quietly depress you every time you walk in.

Everything that touches you is inside the circle of what you must love, because everything that touches you eventually touches the people you claim to love too.

What the Body Knows That the Mouth Denies

Strip away the poetry, and love has a biochemistry. Oxytocin, the so-called bonding hormone, is released during closeness, touch, and trust, and it is what makes attachment feel like warmth rather than obligation. Dopamine gives love its pull, its craving, its addictive early spark.

But here is what most conversations about love conveniently skip: these systems do not run on empty tanks. Chronic stress floods the body with cortisol, and sustained cortisol actively blunts oxytocin sensitivity.

In plain terms, a person who is chronically anxious, physically depleted, or emotionally unresolved has a body that is biologically less able to produce the warmth it wants to give. This is not a metaphor. It is endocrinology. You cannot secrete generosity from a nervous system that is fighting for survival.

Sacrifice Is Real. It Just Isn’t the Point.

None of this means love is free of sacrifice. It isn’t. Real love will cost you sleep, comfort, pride, sometimes money, sometimes years. It will ask you to sit in someone else’s pain when you’d rather look away. But sacrifice is love’s tax, not love’s proof.

The danger is when we start measuring love by how much of ourselves we’ve destroyed for someone else, as though depletion were devotion. Adaeze didn’t love her husband more because she had nothing left. She simply had nothing left. Those are not the same sentence.

I have watched men do the physical version of this: ignoring blood pressure readings, skipping checkups, treating their bodies like machines that owe output and nothing else, all while calling it “providing for the family.” Then the stroke comes, or the diabetes, or the heart that simply gives out at fifty-two, and the very people they were “loving” through neglect of self are left to grieve a love that arrived with an expiry date stitched into it from the start.

You cannot protect what you refuse to preserve.

“Depletion is not devotion. A love that costs you your whole self was never sustainable. It was just slow.”

Loss Is Not Love. Care Is Not Love. Love Is Its Own Thing.

We also confuse loss with love, grieving someone’s absence and calling the ache proof of how much we loved them. Sometimes it is. But sometimes what we mourn is not the person, it is the role they occupied: the routine, the validation, the fear of being alone. Real love, examined honestly, asks: did I want their flourishing, or did I want their presence for what it gave me? These are uncomfortable questions, but they are the ones that separate love from its many convincing impostors: care, habit, fear, loss, duty.

Love is the only one of these that requires you to be whole first.

So, Fill the Cup First

This is not permission to be selfish. It is an instruction to be sustainable. Loving yourself entirely, your body, your mind, the state of your home, the company you keep, the wounds you’ve refused to tend, is not the opposite of loving other people well.

It is the only foundation from which loving them well is even possible. A full cup doesn’t love less generously than an empty one straining to give.

A full cup simply gives from surplus, and surplus doesn’t run dry, doesn’t resent, doesn’t keep silent tallies of what it’s owed.

So before you ask how deeply you can love another person, ask a harder, quieter question first: how deeply have you loved yourself? Whatever number you get back, that is the real ceiling on everything else you claim to give.
