There are moments in life when something happens that makes us feel as though the world has suddenly stopped. The world outside continues to move: people go to work, attend classes, make plans, travel, fall in love, and perhaps build their futures. Yet, internally, we may feel as though we have been left behind.

I experienced this after the end of a long-term relationship. For a while, it felt as though a significant part of my life had stopped moving with the relationship itself. I was still functioning, but emotionally, I often felt as though I was standing in the same place while everything around me continued to move forward.

At first, I thought that moving on meant simply trying to stop thinking about the person, texting or calling them, and no longer checking their updates. However, as I began to learn more about human behavior and neuroscience, I started to understand that letting go may be more complicated than consciously deciding not to think about someone.

Human behavior is shaped by learning, associations, reinforcement, motivation, attention, and memory. From this perspective, moving on can also be understood as a process of learning: learning to respond differently to old cues, while gradually building new patterns of behavior and sources of meaning.

The Brain Learns Through Associations

One of the most fundamental ideas in psychology is that organisms learn associations between events. This concept, known as classical conditioning and most famously demonstrated through Pavlov’s experiments, illustrates how a previously neutral stimulus can acquire significance after repeatedly being associated with another stimulus.

Human relationships are considerably more complex than Pavlov’s classical conditioning experiments, but the underlying principle of associative learning remains relevant. Throughout a long-term relationship, a person becomes associated with countless experiences: conversation, routines, notifications, places, songs, physical proximity, emotional comfort, and expectations about the future.

As a result, a seemingly ordinary cue may eventually carry emotional significance.

A notification from particular person may no longer be just a notification. A photograph may no longer be just a photograph. A familiar place may evoke memories before we consciously decide to remember them. This helps explain why seeing something associated with previous people can sometimes produce an emotional reaction almost immediately.

The response does not necessarily mean that I consciously chose to think about that person. Rather, the cue has acquired meaning through repeated experiences.

Behavior Is Also Shaped by Reinforcement

Operant conditioning provides another useful perspective. Skinner’s work demonstrated how behavior can be influenced by its consequences. Behaviors followed by rewarding or relieving consequences are more likely to be repeated.

Consider a simple example:

I miss someone → I contact them → they respond → I feel relieved.

The relief that follows the behavior can reinforce the tendency to contact that person again when the feeling of longing returns.

This does not mean that every interaction with previous people produces a literal “dopamine hit”, nor does not it mean that people become biologically addicted to their ex-partners. Rather, the broader point is that the brain is constantly learning from the relationship bertween cues, actions, and outcomes.

Repeated interactions can maintain behavioral patterns that were previously associated with emotional reward or relief.

This is one reason why remaining in frequent contact after breakup may be difficult for some people who are trying to move on. The relationship may have ended conceptually, but some of the behavioral contingencies remain. The label may have changed from “partner” to “friend”, while the underlying pattern of seeking comfort, reassurance, attention, or emotional closeness has not yet changed.

Dopamine is More Than Pleasure

This also led me to consider something I had previously learned about dopamine.

Dopamine is often described as the “pleasure chemical”, but this description may be incomplete. Dopamine is involved in several processes related to motivation, learning, and the attribution of behavioral significance. Research on dopamine and reward prediction error has shown how dopaminergic signals can help organisms learn when outcomes differ from what was expected.

In simplified terms, the brain continuously makes predictions:

“If I do this, something rewarding may happen.”

When the actual outcome differs from the expected outcome, that discrepancy can contribute to updating future expectations. This is important because the brain does not simply respond to rewards; it learns to anticipate them.

Over time, cues associated with previously rewarding experiences can become motivationally significant. In other words, something can capture our attention not necessarily because we deliberately chose it, but because our learning history has taught the brain that is matters.

This helped me understand some of my own experiences. Sometimes, seeing a former partner’s social media story can suddenly pull my attention away from whatever I am doing. One moment I am focused on my own life; the next, my mind is imagining what they are doing, who they might meet, and what their future might look like.

The cue is small, however the associative network behind it is not.

Moving On May Involve New Learning

Perhaps the most interesting concept I encountered was extinction learning.

In behavioral neuroscience, extinction refers to a reduction in a learned response when the previously expected outcome is no longer presented. Importantly, extinction does not necessarily erase the original learning. Instead, new learning can develop that changes when and how the old association is expressed.

The distinction changed how I think about moving on.

Perhaps moving on is not about deleting someone from memory, forcing them out of your mind, or revisiting the past. Perhaps it is about learning that the presence or absence of that person no longer determines what I do next.

The old association may still exist. A song may still remind me of them. A familiar place may still bring back a memory. Their name may still produce a brief emotional response. But the response does not have to control my behavior.

I can notice the memory without contacting them. I can feel sadness without interpreing it as a sign that I should return. I can see something that reminds me of them and eventually return my attention to my own life. The goal, then, is not necessarily to erase the past. It is to develop new learning that allows me to live differently in presence of that past.

Moving at My Own Pace

There is another layer to this realization that feels particularly personal.

During the relationship, I was once told that my pace was too slow. That I had not changed enough. That I seemed to be standing still while the other person was moving forward.

For a long time, I interpreted this as evidence that something was wrong with me.

But now, I am beginning to see another possibility.

Perhaps I was moving at different pace.

This does not mean that I had no room for growth. There are certainly things I wish I had understood earlier and aspects of my myself that I wish I had developed sooner. But acknowledging that does not require me to define myself as someone who failed to grow.

Growth is not always linear, visible, or synchronized between two people.

Sometimes we walk. Sometimes we run. Sometimes life forces us to stop. And sometimes, after stopping, we have to learn how to walk again.

I used to think that moving forward meant returning to the speed I had before everything changed. Now, I am beginning to think that, perhaps, moving forward means discovering a new rhythm altogether.

Perhaps Moving On Is Another Form of Learning

The more I learn, the more I realize that moving on may not be a single decision.

It may be a process of repeated learning. Learning that I can experience longing without acting on it. Learning that an old cue does not require an old response. Learning that comfort can come from places other than the relationship I once depended on. Learning that curiousity can exist outside the person I once centered my attention around. Learning that my life can become rewarding again without recreating the life I had before.

Maybe I do not need to erase the past.

Maybe I simply need to build a present that becomes meaningful enough to stand on its own.

And perhaps this is what it means to return to myself. Not to become the person I was before the relationship. Not to become the person someone else expected me to be. But to slowly discover who I am when I am finally given the space to walk at my own pace.

For now, I am still learning. I am still walking. But at least:

I am moving again.

lampu-lampu bintang digantung di langit-langit,

lilin kecil ditempatkan di pojok kanan dan kiri,

menari dan berkelip hingga pagi hari.

Bahkan di bawah meja, di bawah ranjang,

hingga ke lipatan pakaian terdalam di lemari.

Terang menyala tanpa jeda,

setiap jam, setiap menit, setiap harinya,

menciptakan siang yang tak pernah reda,

agar terang bisa menahan segalanya.

Jam dinding menggerogoti tiap detik

lilin di pojok kiri padam lebih dulu,

lampu di bawah meja berkerlap-kerlip lirih,

lalu yang di dalam lemari menyerah,

bintang-bintang di langit kamar jatuh perlahan,

disusul gelap yang bersembunyi di bawah ranjang.

Hingga akhirnya satu yang tersisa,

berada di sisi ranjang,

bergetar, bertahan, lalu padam seutuhnya.

Ketika nyala terakhir runtuh,

gelap merapat dan menenggelamkannya,

menutup pintu pada pagi yang sebentar lagi akan kembali.

Aku tiba di depan rumah kecil itu. Pagarnya dicat dengan warna cokelat kehitaman dengan aksen menyerupai batang kayu. Aku melangkahkan kakiku, kemudian mendorong pagar tersebut. Terdengar bunyi ‘kriiiik…’ dari gesekan logamnnya, seakan-akan telah lama tidak disentuh. Pagarnya kubiarkan setengah terbuka, lalu diriku perlahan memasuki rumah itu.

Sunyi. Tidak terdengar apapun selain kakiku yang melangkah perlahan melewati halaman. Variasi bunga dan rumput liar menumbuhi tanahnya, beberapa terlihat sedang bermekaran dan melambai ke arahku — seolah-olah menyambut kepulangan seseorang yang sudah lama terlupakan oleh rumah ini. Terdapat kursi taman yang masih terawat dengan baik dengan lampu tiang setinggi 2 meter disampingnya yang telah diselimuti sulur bunga terompet ungu, melingkar naik hingga ke puncaknya. Aku memerhatikannya sekejap, lalu kembali berjalan hingga tiba di teras rumah.

Tampak depannya memancarkan kesan sederhana yang hangat, seakan membuka diri bagi siapapun yang ingin masuk. Aku melangkah dengan kaki yang tak beralas, mulai mendorong gagang pintu yang begitu dingin. Di dalamnya, ruang tamu menjadi pemandangan pertama. Kursi-kursi bulunya terlihat empuk, membuat siapapun yang duduk akan larut dalam kehangatan yang memeluk. Posisi kursinya sedikit miring dengan salah satu kaki yang patah. Mejanya diisi dengan sebuah vas berisi anyelir merah muda yang sebagian kelopaknya telah layu. Sementara di temboknya terpajang pigura-pigura foto dengan gambar yang telah mengabur; beberapa sosok di dalamnya sedikit tergores bahkan ada yang sobek di ujungnya. Aku menatap salah satu pigura. Seorang remaja perempuan dengan rambut panjang tersenyum. Ia memakai gaun putih selutut yang membungkus tubuh kurusnya dengan corak warna yang menyebar di bagian bawahnya. Di belakangnya, tampak sawah-sawah yang telah mengering, meninggalkan jejak tanah retak di bawah langit yang cerah.

Aku kembali melangkah, membawa masuk badanku lebih dalam ke rumah yang terasa semakin sunyi. Dari ruang tamu, jalannya mengarah ke ruang makan yang tertata seadanya. Meja kayunya masih berdiri kokoh, tetapi taplaknya kusut dengan beberapa noda yang telah mengering. Kursi-kursi di sekelilingnya tidak lagi tertata rapi; ada yang condong ke depan, ada yang menjauh seakan baru saja ditinggalkan dengan tergesa oleh pemiliknya. Di sudut ruangan, mangkuk dan gelas kosong dibiarkan terbalik. Sementara serpihan-serpihan piring pecah terselip di bawah lemari kecil. Aku mendekati lemari tersebut dan membukanya, di dalamnya piring-piring saling bertumpuk tanpa urutan. Dua diantaranya tampak retak, namun tetap diselipkan di sana.

Dari ruang makan itu, sebuah lorong pendek membawaku menuju kamar yang pintunya tertutup rapat. Bagian bawah pintu kayunya telah dimakan rayap, menyisakan celah kecil yang menganga. Dari celah tersebut, hanya kegelapan yang terlihat. Tanganku mencoba membuka pintu itu, tetapi tak mau bergerak sedikitpun seolah menolak untuk dibuka. Aku menghela napas, bersiap menyerah, hingga jemariku tanpa sengaja menyentuh sesuatu di dalam saku celana. Sebuah kunci kecil dan dingin, yang entah bagaimana bisa berada disana. Dengan nafas yang menderu, aku memasukkan kunci itu ke lubangnya dan perlahan memutarnya.

Udara pengap menyeruak ketika aku membuka pintu kayu tersebut. Dari atap yang berlubang, seberkas cahaya tipis merayap masuk. Membentuk garis pucat yang nyaris tak mampu menembus pekatnya ruangan. Jendela tertutup rapat dengan gorden sobek yang diselimuti oleh debu. Aku meraba-raba tembok, mencoba menemukan saklar lampu. Dengan mengandalkan setipis cahaya tersebut, jemariku menemukan saklarnya. Ruangan yang tadinya pekat kini terkuak oleh cahaya redup yang memperlihatkan seisi kamar. Sebuah lemari kayu masih berdiri kokoh di sudut ruangan. Sisi kiri pintunya terbuka lebar, menampilkan pakaian-pakaian yang dipenuhi noda warna pekat yang tak beraturan. Corak warna yang sama dengan gaun remaja perempuan yang ada dalam pigura foto. Meja belajarnya tampak berantakan; pulpen dan buku-buku terjatuh dan berserakan di lantai, beberapa halamannya terlipat dan sobek. Mataku menyusuri setiap sudut ruangan. Sebagian dinding tembok telah berlubang kecil dan retak. Banyak goresan dan garis-garis memanjang yang warnanya nyaris memudar. Namun, diantara yang lama dan pias itu, tampak beberapa goresan yang masih jelas warnanya. Sementara itu, lantainya terlihat kusam, dengan retakan-retakan yang menjalar seperti garis-garis waktu.

Ranjang sempit menempel di dinding tembok. Diatasnya, hanya tersisa satu bantal yang telah lapuk dan sebuah boneka kecil yang telah robek hingga isinya mengintip keluar. Di tengah itu semua, terdapat selimut tipis masih terlipat rapi di ujung ranjang tersebut. Aku mendekati ranjang dan menjatuhkan badanku di kasur. Selimut tipis itu kutarik hingga menutup sebagian tubuhku, menyisakan kaki yang masih terlihat telanjang dan gemetar halus oleh hawa kamar yang menusuk. Dinginnya merambat seperti ingatan yang tidak ingin kembali.

Aku memejamkan mata. Samar-samar mencium aroma sesuatu yang dulu pernah begitu akrab. Anyelir Merah Muda. Aroma itu seharusnya tidak ada disini. Vas bunga tersebut berada di ruang tamu, bahkan sebagian kelopak bunganya telah layu. Wanginya semakin menyeruak, seolah-olah muncul dari sela-sela pori tembok yang retak. Terdengar suara samar dari balik dinding — lirih, seperti seorang anak yang sedang tertawa atau menangis, atau mungkin keduanya sekaligus.

Perlahan aku membuka mata, cahaya matahari merembes masuk, membelah gelap yang tadinya sempat membungkus. Segalanya seakan mengendur, larut seperti kabut yang disapu angin pagi. Aku menarik napas panjang dan mengerjapkan mata beberapa kali. Bunga Tidur. Ketika raga mulai tersadar, samar-samar aku menyadari: rumah itu tidak pernah ada. Tetapi perasaannya tetap tinggal, seperti aroma anyelir yang menempel di ruangan tersebut, menolak untuk benar-benar hilang.

bercakap selayaknya tidak tahu menahu,

lagaknya bak seorang kawan yang sering bertemu,

nyatanya hanya cangkang semu yang berpura-pura lugu.

mereka,

bersembunyi di balik alibi,

saling berlomba menolak afirmasi — hanya untuk kepuasan diri sendiri.

berbicara dengan segala argumentasi,

seolah tahu apa yang terjadi; padahal dirinya sendiri kurang diperbaiki.

mereka,

ada dimana-mana,

mengenakan senjata yang sama: topeng beribu muka.

bersorai ketika lawannya tercerai-berai,

mencaci ketika lawannya berprestasi.

mereka,

hanyalah jiwa-jiwa palsu,

bersembunyi di balik bayang-bayang nurani,

menipu dunia sambil menertawai sandiwara yang mereka cipta sendiri.

merasuki jiwa tanpa henti,

menusuk sukma dengan berbagai cara agar aku berhenti

lelah, lemah, putus asa, dan hampa—

ia mencitai reruntuhan di dalamku.

sementara aku: menahan pagar kayu yang nyaris patah,

sambil mendecit lirih diantara batas rumah tersebut.

tubuh ini dipenuhi noda; terkikis sedikit demi sedikit,

pun ruang kian menyempit hingga nafas bisa terasa sulit.

jiwa yang retak, menahan gema yang tak pernah diam,

rangkanya dipenuhi salur-salur hitam yang mengakar kuat.

apakah mereka peduli?

apakah mereka bersimpati?

apa yang diharapkan dari carut marut benang kusut ini?

segalanya seakan mulai hangus, dengan jiwa yang nyaris runtuh.

raga ini taman layu,

di atasnya pikiran tumbuh sembarang tanpa arah, menjalar seperti ilalang.

aku hanya ingin menapak tanah sebentar,

diam,

agar bisa menumbuhkan diriku lagi.

riuh rendah kini bermunculan,

disusul datangnya Sang Hitam ke permukaan,

terbangun setelah mengamati potongan-potongan hidup manusia,

yang terabadikan lewat semesta maya.

berputar berulang kali — memenuhi ruangan yang tak berujung.

ia hanyut dalam lautan cerita,

berjalan menuju tepian yang tak pernah nyata,

satu per satu mencoba merasuk ke dalam jiwa,

berharap dapat merengkuh sisi terang setiap kepala,

sebelum ia lenyap tak bersisa.

Sang Pengawas menatap tanpa henti

jemarinya menari; bola matanya menelusuri cahaya yang tak ia mengerti.

waktu seakan berlari, tubuhnya kehilangan bayangannya sendiri,

menyisakan sunyi dan keretakan yang kian tak bisa bersembunyi.

Dua Belas Malam,

hanya tulang rasa yang tersisa,

bergetar dengan ringkih setiap kali,

ia menatap terlalu dalam.

“Lantas, kemana lagi aku bisa percaya?”
