Why Can't I Stop Thinking About Someone? Effective Strategies to Stop Obsessing
You can’t stop thinking about them.
It’s constant. Replaying conversations, analyzing every detail, wondering what they meant, what you did wrong, or what you could have done differently.
I see this all the time in my therapy practice as a Licensed Marriage and Family Therapist. My clients come in feeling frustrated, exhausted, and honestly a little out of control with how much space one person is taking up in their mind.
If that’s you, there’s nothing “wrong” with you, but there is something important going on underneath it.
Understanding why the brain tends towards preoccupation with someone can be the key to “unhooking” our obsessive thoughts from dragging us down.
This comprehensive guide is broken into 3 parts:
Part 1: 5 Types of People We Get “Stuck” On
5 Types of People We Get “Stuck” On
Ever wonder why your brain never turns off, the endless cycle of over analysis and overthinking about someone?
To better help my clients understand the nature of their obsession, I created 5 categorizations of the qualities of a person we might become obsessed with, though many will fit into more than one category:
Symbolic Idealization
Unrequited Attachment
Scarcity Attraction
Forbidden or Obstacle-Drive Attachment
Intermittent Reinforcement Attraction.
1. Symbolic Idealization:
Individuals who represent qualities, characteristics, or archetypes of importance to us.
This is when we “project” our ideas of what the person means to us, and it clouds our ability to objectively assess and analyze their true qualities as an individual.
For example, someone may become emotionally invested in a priest or pastor because the position itself represents safety, wisdom, or integrity to them, even if the person’s actual behavior in their relationship is inappropriate, unhealthy and impulsive.
Some examples:
People who remind us of people from our past (parents, a deceased child, an old friend)
People with a perceived power, authority, or influence such as bosses, managers, teachers, professors, and government leaders.
Individuals who played an important emotional role during a significant or vulnerable time in our lives ( “they were the only one there for me after my father passed,” “I saw them as my hero”)
People who present with qualities we look up to, admire, and aspire to (sense of humor, confidence, financial abundance, physical attractiveness)
2. Unrequited Attachment
A persistent emotional or romantic fixation on someone who has shown or told us that they do not want a relationship with us.
We might believe that if we just love them enough on our end, if we work hard enough, help them enough, get them to see our perspective, get them to forgive us, then finally our hard work will result in a satisfying relationship with them.
This can also occur when we have a wounded pride or ego, particularly when someone rejects or ends the relationship in a way that leaves us feeling powerless, replaced, or lacking closure.
Some examples:
Former partners who ended the relationship
Estranged family members who tell us they need space
Friends or acquaintances who distance themselves by canceling plans, not responding to texts, blocking/ghosting
3. Scarcity Attraction
People who are not able to fully meet our relational needs due to their circumstances or inherent unavailability.
When someone’s interest is inconsistent or scarce, the resulting anxiety and uncertainty can intensify our pull towards them and feel like a “spark” when our minds interpret the strong feelings as a sign of importance, and that to relieve the anxiety we need to pursue further closeness with this individual.
We can even romanticize this uneasy feeling; think of all the songs written about people who can’t sleep, can't eat, are totally distracted and obsessed with someone who barely gives them any interest in return.
Some examples:
Romantic pursuit of someone already in a committed relationship (e.g., married or dating someone else)
Emotionally Unavailable: People who are emotionally shut down, (due to trauma, addiction, or unresolved personal issues). Their perceived wounded nature can activate those of us prone to want to “fix” or “help” others.
Unable or unwilling to invest in the relationship: Someone who gives the bare minimum to keep us interested but are not fully meeting our relationship standards and needs.
4. Forbidden or Obstacle-Driven Idealization
People who are out of reach due to circumstances or status can feel particularly enticing when there is an element of striving for their attention, obstacles to overcome to communicate and get their attention, or an element of secrecy involved.
The pursuit itself can create meaning and value in the relationship rather than the actual quality of the connection.
Some examples:
Individuals in inaccessible situations (e.g., incarcerated persons, cults/ isolated communities)
Public figures, celebrities, and parasocial relationships
Fundamental communication barriers: when two people cannot easily communicate due to language differences, cognitive abilities, or cultural divides, it can create an illusion of mystery or romanticized longing.
Situations where logistics make a relationship nearly impossible, such as:
Geographically unavailable
Relationships prohibited by workplace or school policies, professional ethics, or legal constraints
5. Intermittent Reinforcement Attachment
Intermittent reinforcement in this context occurs when we receive occasional gestures of perceived attention, kindness, or interest but we never know when it’s going to happen next and cannot identify any patterns that elicit them.
Because they are so unpredictable, they can feel extra special or magnified in their meaning to us, and the relationship. These hot-and-cold behaviors can fuel ongoing fixation, even when the overall pattern reflects consistent disinterest from the person.
Over time, we can become more emotionally preoccupied with earning or recovering the connection than evaluating whether the relationship is actually healthy, mutual, or fulfilling.
Some examples:
Relationships with repeated breakups and reconciliations
Abuse or toxic relationship cycles involving periods of mistreatment followed by apologies, affection, promises to change, or “honeymoon phases”
Online or long-distance relationships where sporadic contact intensifies emotional anticipation and fantasy
Relationships where communication becomes addictive because responses are unpredictable (e.g., anxiously waiting for texts, social media likes)
Part 2: The Signs of Unhealthy Obsession
It can be hard to tell when thinking about someone has crossed into something unhealthier, especially when it feels meaningful or important.
Below are some common signs to look out for. Under each one, you’ll find a few questions to help you reflect more honestly on your situation and meant to be used as journal prompts (I often use these in therapy sessions to help my clients take a deeper look at the nature of the relationship).
These are meant to help you gently reality-check what’s actually happening, not just what you hope is happening.
1) Ignoring the Reality of the Relationship
Has this person, through their actions or words, shown that they are unwilling, unable, or uninterested in having a relationship with you?
What recent actions, words, or lack of effort from this person are you overlooking or downplaying to hold onto the hope that the connection still exists?
If you hypothetically stopped initiating, accommodating, or making excuses for this person, what would realistically happen in this relationship?
2) Putting Your Life on Hold
Are you holding off on pursuing other potential connections with the hope that eventually your person of interest will finally be available to you?
What opportunities or experiences have you turned down to keep space in your life for this person?
3) Unequal Effort: Is the Balance Off
Think about the resources you have already put into this person- your time, money, energy, and things you’ve done to benefit this person- does it match their efforts toward you?
Are your investments in this person of interest taking away from other areas of your life that deserve your time and attention?
4) Living in Excuses and Rationalizations
What excuses or rationalizations do you use to validate the reasons the relationship has not changed in the way you desire? (for example, do you mentally bookmark evidence of interest from the person that occurred many months or years ago?)
What am I hoping will change in this relationship, and what evidence do I have that things will change?
Part 3: Strategies to stop obsessing over someone
Break the Fantasy Spell by Naming the Storyline
Try taking a more critical look at the vision you’ve created in your mind with this person.
When we are stuck ruminating about a person it’s often because we are not yet ready to let go of our dreams, fantasies, and expectations of what our future could have been with this person.
Notice when you are using memories from the past to fill in the gaps of the uncertainty, pain, or disconnection we currently feel.
Now, try naming it for what it is, a beautiful memory, an enticing fantasy, or a story from the past. When the thoughts come up, label and name them.
Give these thoughts with a common theme a name, as if you were naming a story, for instance, the “If only they understood story” or the “meant to be together love story,” or the “life was perfect when they were still alive story.”
When these thoughts come up, you can recognize and name the story and decide whether you want to “open the book” so to speak, and engage with the storyline, or decide you can put the book aside for now.
See if you can gently hold onto both truths at the same time: you can still honor and cherish the positive memories/visions you have with this person and still hold the reality that it is not the current reality you live in.
Release the Relics of the Past
When you have strong feelings for someone, it’s normal to find yourself researching, exploring, and cherishing all things your person of focus is interested in. Sometimes these rituals, objects, and routines become a way of maintaining a sense of connection, even after the relationship has ended or remained unreciprocated.
Here are some areas to consider to lessen the chances of falling back into old familiar patterns of obsessive thinking:
Limit your ability to re-read old text messages or repeatedly looking at photos
Letting go or putting into storage sentimental items such as gifts, clothing, letters, or old tickets from shared experiences
Distance yourself from reminders of their interests, hobbies, sports teams, music, or routines of the past
Limit going to places or events in hopes of unexpectedly seeing them
Part of healing often involves gradually letting go of these reminders, rituals, and “possibilities,” while refocusing your energy on building a life that reflects your own current needs, values, and desires.
Accountability from our Support Systems
You might share with those close to you about your intention to try to move on to help keep you accountable in a kind and supportive way.
For instance, asking friends and family not to bring the person up in conversation, and letting them know you’re working on moving forward. If they catch you slipping into a nostalgic or obsessive loop, they can gently remind you of the boundary you’ve set.
Our loved ones can show support and empathy for our internal struggle while also maintaining clear boundaries. That might mean not asking loved ones to not engage with you in long analytical conversations about why the relationship didn’t work out, not passing along updates about the other person, and not indulging endless “what if” scenarios.
Embrace a Grief Response
Losing someone, even if it is the loss of a past relationship, imagined future, or unrealized potential with them, is still a genuine form of loss.
When someone dies, we tend to understand that grief responses are normal. But when the person is still alive, especially if the relationship was undefined, one-sided, or never fully became what we wanted it to be, we often judge ourselves for struggling to let go.
We can grieve lost relationships, lost hopes, lost versions of ourselves, and futures we deeply imagined but never got to experience.
If you allowed yourself a little more self-compassion and understanding, by labeling this experience as a legitmiate grief process, what might you do differently? How would you treat yourself differently in this process and who or what might you lean on for support during this time?
Detach From Intrusive Thoughts
In Acceptance and Commitment Therapy, the type of therapy I provide in my therapy practice, the concept of “defusion” is when we take a step back from the pull of thoughts that we find unworkable (meaning they don’t lead use to act in a way that creates a rich and meaningful life for us).
There are many strategies for defusion of unhelpful thoughts that can be taught through a trained Acceptance and Commitment Therapist, here’s one to try:
Visualize the thoughts and feelings as leaves on a stream, each thought getting placed on a leaf and watching it flow down a stream or river. This is a metaphor for how our thoughts and feelings come and go into our awareness, and we don’t have to stop and focus on any specific thought that comes up.
Rebuild Your Life With Intention
Putting a pause on your life to wait around for an uninterested person to become available and interested in a relationship will lead to chronic disappointment and dissatisfaction.
Remind yourself that moving on in your life does not mean you permanently close the door on this person or relationship. You may decide to keep open to future connection when circumstances or feelings change, and at the same time decide that your time and energy is better utilized elsewhere for this time-being.
Consider changing up your living arrangement, job, or routines that you’ve remained in if they have kept you psychologically/physically close to the person.
Try asking yourself, what brings you joy? Getting back in touch with what brings you joy and excitement in your life is important to move on.
Seek Professional Therapy Guidance if Needed
It’s worth considering therapy or counseling to explore what might be blocking you from establishing more reciprocal connections with people that add value and meaning to your life, rather than the shallow nature of relational obsession.
There is something usually deeper below the surface if you are finding yourself connecting with an unavailable person in such a passionate manner, such as an attachment wound that led to an insecure, avoidant, or anxious attachment style.
Signs it is time to seek professional clinical therapy:
Difficulty sleeping due to overthinking, anxiety, and ruminations
Uncontrollable tearfulness and crying spells
Hopelessness about your life post-ending the connection
Anxiety-driven inappropriate outreach attempts (such as calling/texting a person numerous times in a row)
Compulsive behaviors that reconnect/connect that you regret afterward
Obsessive thinking interfering with focus and performance in work, school, or other responsibilities.
