How To Stop Thinking About Someone: Tips For Letting Go

If you find yourself constantly thinking about someone and unable to let them go, you are not alone. This is a common experience, and there are practical strategies that can help—including meeting with an online therapist. BetterHelp providers have helped over six million people work through concerns like these.

From a psychology perspective, thinking about someone frequently is common; however, when it begins to impact your daily life, it may be worth addressing. This article explores why these thoughts happen, when they may become unhealthy, and what you can do to move forward.

Why you can't stop thinking about someone

If you're constantly thinking about someone, it may not be a sign that something is wrong, but it's also unlikely to be random. In psychology, persistent thoughts can be linked to how the brain processes attachment, emotion, or uncertainty, especially when you are experiencing a connection with someone that feels unresolved, meaningful, or intensely emotional.

The brain's reward system and emotional bonding

At the start of a relationship, strong emotions and physical attraction can impact how the brain processes the experience. Excitement and intense emotions may activate dopamine reward pathways, which can make the experience feel all-consuming. In this stage, the brain is learning and trying to predict what's next by replaying conversations and searching for meaning. Essentially, it's examining the evidence and making predictions to reduce uncertainty.

Attachment styles and why some people ruminate more

Attachment styles can also influence how often these thoughts occur. People who have anxious attachment styles may be more likely to ruminate on close relationships. Whether it's a best friend, a family member, or a potential partner, the brain focuses on maintaining that connection and reducing uncertainty. This can manifest as ruminating thoughts, such as:

• What did they mean by that comment?
• Are they mad at me?
• Did I do something wrong?

These thought patterns may be less about the relationship itself and more about personal experience and meeting attachment needs.

Intermittent reinforcement and mixed signals

Intermittent reinforcement may be a significant driver of obsessive thinking. When you get consistent affection or attention, it reinforces the stability of the relationship. The brain can relax. But intermittent reinforcement of unpredictable texts, sporadic affection, or hot-and-cold attention can keep the brain on high alert, constantly searching for patterns and meaning.

Unresolved endings and one-sided relationships

A one-sided relationship or an unclear ending can leave the mind searching for an answer, even if it's in the form of closure. For example, if you went on one date with someone and it went well, but they stopped responding to your text messages, your brain may begin to fast-forward to your idea of what might have happened. When the present reality doesn't form as you expected, your brain can start to fill in the gaps, which can make it more difficult to let go. Understanding these patterns can help you recognize when your thoughts may be crossing into unhealthy territory.

When obsessive thinking becomes unhealthy

To determine whether thinking about someone all the time is a concern, it can help to understand the difference between a healthy preoccupation and obsessive thinking.

A healthy preoccupation:

• Often feels pleasant
• May motivate you
• Doesn't interfere with your ability to function in daily life

On the other hand, obsessive thinking can:

• Feel intrusive or distressing
• Cause repeated, uncontrollable thoughts that lead to anxiety
• Lead to rumination
• Interfere with concentration or sleep

Recognizing which category your thoughts fall into can help you determine whether additional support might be beneficial.

Signs your thoughts may be interfering with daily life

Constantly thinking about someone can make you feel sad or preoccupied, distracting you from other priorities. Some people may also grow frustrated or guilty for not moving on. It can be helpful to recognize when these thoughts have crossed from normal processing into something that may need attention. The following signs may indicate that your thoughts are interfering with your well-being:

• Disrupted sleep or difficulty falling asleep because of racing thoughts
• Trouble concentrating at work, at school, or on daily tasks
• Withdrawing from friends, family, or social activities
• Physical symptoms of anxiety, such as a racing heart or muscle tension
• Neglecting self-care routines or responsibilities
• Feeling unable to enjoy activities you used to find fulfilling

When to seek professional support

If you've been experiencing persistent, intrusive thoughts about someone for several weeks or longer and these thoughts are significantly impacting your sleep, work, relationships, or overall emotional well-being, it may be time to consider professional support. A therapist can help you understand the underlying patterns driving these thoughts and develop tailored strategies for moving forward.

In addition to online therapy, BetterHelp now offers psychiatry services through Uplift as another care option.

Seeking professional help may support you in finding balance and maintaining emotional well-being.

How to stop thinking about someone

Willpower alone may not be enough to let go of persistent thoughts. It can be natural for the brain to revisit relationships that meant something to you, especially when the ending was unresolved. Learning intentional strategies may be necessary to change thought patterns. Here are some approaches that may help:

1. Create digital distance and boundaries

2. Practice the no-contact rule

3. Redirect attention to other relationships and goals

4. Use mindfulness to interrupt thought patterns

5. Stay physically active

6. Challenge the fantasy with reality

7. Consider whether reaching out to them is right for you

Create digital distance and boundaries

Phone numbers, saved chats, text messages, and access to social media profiles all keep someone mentally present, even when there is no longer a relationship. This easy access can encourage looking for signs that the connection is still a possibility, rather than allowing distance to form. Creating digital distance may include blocking phone numbers, deleting text messages, muting or unfollowing the other person on social media, or removing photos from your camera roll. Giving yourself space may help your mind process and let these emotions go.

Practice the no-contact rule

The no-contact rule involves intentionally avoiding all communication with the person you're trying to stop thinking about for a set period of time. This means no texting, calling, checking their social media, or reaching out through mutual friends. The purpose is to give your brain the space it needs to begin healing without the constant reinforcement of their presence. While it can feel difficult at first, maintaining no contact may help reduce the intensity of thoughts over time.

Redirect attention to other relationships and goals

Another way to stop thinking about someone can be to prioritize other close relationships and personal interests. You can nurture close relationships you already have by spending time with your friends and family, which can remind you that you can feel strongly for many people. Also, staying engaged in hobbies or activities you care about can strengthen resilience, help you feel fulfilled, and provide a distraction that helps you resist intrusive thoughts.

Use mindfulness to interrupt thought patterns

If you are prone to obsessive thinking, mindfulness techniques can help you acknowledge these thoughts and let them go. One approach is to notice when the thought arises, name it without judgment (such as saying to yourself, "I'm having a thought about them again"), and then gently return your attention to the present moment. Mindfulness may help weaken rumination over time and positively impact future mental health. The brain gradually learns that having repeated thoughts about the person is optional and something it can control, which gives space for balance and recovery.

Stay physically active

Physical activity may be a helpful tool for managing intrusive thoughts. Exercise may release endorphins, which can improve mood and reduce stress. Movement may also give your mind something else to focus on, potentially breaking the cycle of rumination. Whether it's going for a walk, taking a fitness class, or simply stretching, staying active can help you process emotions and create mental space away from thoughts about the other person.

Challenge the fantasy with reality

When contact is limited or unclear, the brain may fill in the gaps with imagined scenarios, which often do not align with what is actually happening. It can be easy to make up scenarios in which the other person feels the same way or that explain away the lack of communication. To challenge the fantasy with reality, try writing down what you actually know about the situation versus what you've imagined. Ask yourself whether your thoughts are based on evidence or wishful thinking. This practice can help you see the situation more clearly and reduce the power of idealized scenarios.

Consider whether reaching out is right for you

Sometimes, even after doing everything you can to stop thinking about someone, you may still want to reach out. Before doing so, it may be helpful to reflect on your intentions. Think about why you want to reconnect. Are you looking for closure or reassurance in the relationship? Are you hoping the connection will pick back up? Reflecting on your motivation can help you avoid impulsive behavior and ongoing disappointment. If you still decide to reach out, set realistic expectations and remember that the other person may not feel the same way or even respond. It may also be helpful to respect their boundaries if they have clearly stated that they do not want to hear from you.

Healthy ways to process feelings instead of suppressing them

Suppressing feelings can make obsessive thoughts worse. Focusing on healthy processing can help you understand your emotions, allowing you to respond with intention rather than reacting impulsively.

Journaling and reflection

Journaling about your thoughts and experiences can help you understand what the person you're thinking about means to your life and get a better idea of why your thoughts are centering on them. Reflecting on personal experiences also helps you separate reality from the scenarios your brain has created. Journaling can give you a safe space where you can explore what happened and identify patterns without worrying about judgment.

Accepting feelings without judgment

Feeling connected to someone is a part of human nature, and you can have feelings for someone without behaving impulsively. Accepting this fact may help you avoid unhealthy behaviors and ruminating thoughts. Try to approach these thoughts with curiosity rather than shame.

Leaning on your support network

Talking to trusted friends or family members about what you're going through can provide relief and perspective. Social support can help you feel less alone in your experience and may offer insights you hadn't considered. Sometimes simply voicing your thoughts out loud can reduce their intensity and help you process them more effectively.

Building self-worth during the healing process

Obsessive thinking about someone can sometimes erode your sense of self-worth, especially if the relationship was one-sided or ended painfully. Taking time to reconnect with your own values, strengths, and goals may be a helpful part of healing. Also, engaging in activities that make you feel capable and fulfilled can help rebuild confidence and remind you that your worth is not dependent on another person's attention or affection.

Benefits of online therapy for obsessive thoughts

Online therapy can be a helpful resource for finding the courage to face your feelings and take steps to heal. One key benefit is the ability to message your therapist when intrusive thoughts arise throughout the day, rather than waiting for a scheduled appointment. Your therapist will respond to your message as soon as they're able, and you can also discuss it in your next session. Additionally, the comfort of attending sessions virtually from home can feel less intimidating when you're emotionally vulnerable, making it easier to open up about relationship issues and attachment patterns.

How effective online therapy can be

One study published in JMIR Mental Health in 2020 found that digital therapy may have outcomes similar to in-person therapy for symptoms of anxiety and depression. Although not every person has the same experience, online therapy may be an option for people working through rumination, attachment concerns, or other distress related to thinking about someone constantly. BetterHelp offers one of the world's largest therapist networks, with over 30,000 qualified providers globally. Online support from a therapist may help when persistent thoughts begin to affect daily life.
