How to keep long-term love strong
Long-term love runs on daily deposits, not grand gestures. Two underrated engines — gratitude and novelty — keep attraction alive after the honeymoon phase.
Long-term love does not weaken because people stop caring — it weakens because couples stop making small deposits. Gottman’s research shows that turning toward a partner’s bids for connection, even in trivial moments, predicts relationship stability better than conflict style or compatibility. The daily choices are the relationship.
Why the honeymoon phase fades — and what that has to do with you
The early intensity is not love at its peak. It is infatuation, driven largely by dopamine and the novelty of someone new. That system is not built to last — evolutionary speaking, sustained infatuation would be metabolically ruinous. The neurochemistry quiets, and what couples discover underneath it is either a relationship they have been actively building or a gap they have been papering over with excitement.
Esther Perel (2006) frames the post-honeymoon period as the defining test: can you generate desire in the presence of security? Her answer is yes — but it requires accepting that long-term love is not the same as early love, and that the tools for sustaining it are different. Familiarity is not the enemy of desire; neglect of novelty is.
The practical implication is uncomfortable: you cannot coast. Relationships that feel stable without investment are usually accumulating invisible debt. The couples who describe their relationship as still alive after ten or twenty years are almost always the ones who treated maintenance as a responsibility, not an indulgence.
Two underrated engines: gratitude and novelty
Most relationship advice defaults to communication and conflict resolution — useful, but they address problems. Gratitude and novelty are what build the surplus that makes conflict survivable.
Gratitude works by reversing the familiarity tax. The longer two people live together, the more their partner’s contributions become background noise. You stop noticing the coffee made, the logistics handled, the detail remembered. Gottman’s prescription in The Love Prescription (2022) is specific: name the routine acts, not just the exceptional ones. ‘Thank you for making sure we had milk’ is not a small thing when said with presence — it signals that you are still paying attention. Partners who feel seen tend to increase effort; it compounds.
Novelty sustains desire because familiarity alone erodes the sense of self-expansion. Arthur Aron’s research on shared novel activities demonstrates that couples who regularly do things neither of them has done before report higher relationship satisfaction than those who stick to comfortable routines. The mechanism is not excitement for its own sake — it is that each person becomes, again briefly, a source of new experience for the other. This is the same dynamic that made the early relationship feel alive. You can engineer it deliberately. See our piece on attraction and dating for more on how novelty operates in the psychology of desire.
The explicit stance: small daily deposits beat grand anniversaries
Here is the unhedged claim this post is making: the anniversary dinner is overrated. Not worthless — rituals matter — but the evidence is clear that relationship health is built in the unremarkable daily moments, not the milestone events.
Gottman’s concept of the emotional bank account makes the math legible. Every bid for connection that is met adds a deposit. Every bid ignored or dismissed makes a withdrawal. Grand gestures are single large deposits that do not offset the deficit accumulated by months of small withdrawals. A week of consistent turning-toward — noticing, responding, touching deliberately — builds more trust than a weekend away planned to make up for inattention.
This is also where Kanwer Singh’s (Humble the Poet) framing in How to Be Love(d) (2022) lands hardest. Love as a feeling is unreliable; love as a daily practice is something you can actually do. On the days when the feeling is faint — and in every long relationship those days exist — choosing the action is what sustains the relationship and, with time, regenerates the feeling.
Robert Greene’s observation in The Art of Seduction (2001) adds a useful counterpoint: one genuine sacrifice, something that visibly costs you something, carries more relational weight than months of verbal reassurance. The reason is credibility. A sacrifice makes your prioritisation legible in a way that words cannot replicate. Ethically applied, this is simply about being willing to be inconvenienced for the person you love — and making sure they can see it.
One final principle from Kevin Fredericks (Marriage Be Hard, 2022): dream together, not merely side by side. Long-term couples who share forward-facing vision — a place they want to go, something they want to build, a goal that belongs to both — have a source of energy that pure contentment cannot supply. The relationship becomes a project, not just a state.
For the conversational structure that makes all of this feel less forced, our guide on communication for couples is the natural next step — particularly the section on how to build rituals around daily check-ins without them becoming interrogations.

FAQ
Does the honeymoon phase have to end?
The initial euphoria fades for nearly every couple — that is biology, not failure. **Dopamine-driven infatuation** typically peaks in the first 12–18 months, then gives way to a calmer attachment system. What couples choose to do after that transition is what separates lasting love from slow drift. **Esther Perel (2006)** argues the challenge is not to recreate the early rush but to build a different, richer kind of desire — one that requires active cultivation rather than simply being felt. The end of the honeymoon phase is the start of the real relationship, not its decline.
What does 'turning toward' mean and why does it matter?
**Turning toward** is John Gottman's term for the micro-responses that build emotional connection. When your partner makes a bid — a comment, a question, a reach for physical contact — you can turn toward (engage), turn away (ignore), or turn against (dismiss). **Gottman's research** found that couples who stayed together turned toward each other in roughly **86 % of bids**, while couples who divorced did so only around 33 %. These are not dramatic moments. They are the small, repeated choices that either fill or drain what Gottman calls the _emotional bank account_. Consistency here matters far more than occasional grand gestures.
How can gratitude strengthen a long-term relationship?
Gratitude works by counteracting the **negativity bias** that familiarity amplifies. The longer we know someone, the more their ordinary efforts become invisible — we stop noticing them and start expecting them. **Gottman (The Love Prescription, 2022)** recommends expressing thanks specifically for routine acts: a made coffee, a picked-up dry-cleaning run, a remembered detail. The specificity is the point — 'thanks for handling that' signals that you actually saw the effort. Partners who feel seen increase their own effort; it is a compounding loop, not a transaction.
How do you keep curiosity alive in a long-term relationship?
Treat your partner as **perpetually incomplete** — because they are. People change continuously, and the version of your partner you knew at year two is not the person at year ten. **Gottman** recommends open-ended questions that go beyond logistics: not 'how was your day?' but 'what is something you have been thinking about lately that you haven't told me?' This kind of curiosity also signals respect — it communicates that you still want to know, not that you assume you already do. Our guide on [how to express needs to your partner](/en/blog/express-needs-to-your-partner) covers the conversational moves that make these exchanges feel safe rather than clinical.
Why does novelty help sustain attraction?
**Arthur Aron's self-expansion research** shows that humans are drawn to experiences that grow their sense of self. In early relationships, partners expand each other constantly — new perspectives, new activities, new feelings of aliveness. Over time, if the couple stops generating new shared experiences, each person stops being a source of growth for the other. The solution is intentional novelty: activities neither of you has done before, a different restaurant neighbourhood, a weekend trip somewhere unfamiliar. **Esther Perel (2006)** frames this as the interplay between security and freedom — desire needs some distance and mystery to survive proximity.
Is physical touch really that important after years together?
Yes, and it is more likely to decline than people expect. **Gottman** recommends making **non-sexual physical touch a daily habit** — a hand on the shoulder, a kiss that lasts more than a second, a hug that is not rushed. Touch activates the oxytocin system independently of sexual desire, which is why its absence can make partners feel like roommates even when the relationship is otherwise functioning. The key distinction is _deliberate_ touch: touch that says 'I am here, I notice you' rather than touch that is purely transactional.
What is 'love as a verb' and why does it matter for long-term couples?
The idea, articulated by Kanwer Singh (Humble the Poet) in *How to Be Love(d)* (2022), is that love is not a feeling you passively receive — it is a **set of actions you choose, repeatedly**. This reframe matters for long-term couples because the feeling of love fluctuates by design; relying on it as a signal tells you nothing about what to do on the days it feels faint. Choosing the actions — the check-in, the touch, the question — tends to regenerate the feeling, not the other way around. Singh also warns against ego-driven **approval-seeking** that substitutes for genuine connection; long-term love requires less performance and more presence.
How much scheduled 'couple time' do you actually need?
There is no universal number, but the research consensus points toward **regular and protected** rather than occasional and grand. **Gottman** treats one-on-one fun time as non-negotiable maintenance — not a reward for good weeks, but a structural feature of the relationship. The format matters less than the consistency: a Wednesday walk counts more than an infrequent weekend away if the walk happens every week. See our piece on [communication for couples](/en/blog/communication-for-couples) for a practical approach to designing conversations during those protected slots, especially when daily life has crowded them out.
Can a single sacrifice really outweigh months of reassurance?
**Robert Greene (The Art of Seduction, 2001)** makes the counterintuitive claim that one genuine sacrifice — something that costs you something real, visibly chosen for the other person — lands with more emotional weight than sustained verbal reassurance. The reason is credibility: words are cheap and repetitive; a sacrifice demonstrates prioritisation in a way that cannot be faked. The ethical reframe here is important: this is not manipulation, it is legibility. Telling your partner they matter is less visible than showing it through a concrete choice that makes the preference unmistakable.
What is the biggest threat to long-term love?
**Contempt**, by a significant margin. Gottman's decades of research identify contempt — eye-rolling, sarcasm, mockery, superiority — as the single strongest predictor of relationship breakdown, far more destructive than conflict or distance. Contempt communicates 'I see you as beneath me,' which erodes the emotional safety that everything else depends on. The earlier warning sign is **criticism of character** rather than behaviour: 'you never think of others' rather than 'that comment landed badly.' Our guide on [the positivity ratio](/en/blog/the-positivity-ratio) explains the research on how many positive interactions are needed to offset a single negative one — the math is less forgiving than most couples assume.
