Breakups, Broken Hearts, and Moving On is a weekly podcast about healing broken hearts, building confidence, and moving forward in an empowered way. It is the perfect balance of science, spirituality, and sass.

With a heavy dose of optimism, I share what I’ve learned from personal experience AND as a breakup coach to help you though this time.

With over 200 episodes, it is more than a podcast, it is a resource library for people on any phase of their breakup healing journey.

You can—and will—miss things that are not good for you.

That can be difficult to accept when your mind keeps replaying the sweetest parts of a relationship: the trips, the affection, the first “I love you,” the great sex, or the private jokes. Meanwhile, the conflict, incompatibility, disappointment, or harm that contributed to the breakup can feel strangely distant.

So you may be asking, Why, during a breakup, do I always think about the good times? Does it mean the relationship was better than you realized? Was ending it a mistake?

No.

Happy memories are real, but they are not a complete record of the relationship. During a breakup, your brain is processing loss, trying to explain pain, and reaching for familiarity. That can make the good times feel unusually vivid—and unusually persuasive.

Understanding why this happens can help you stop treating every warm memory like a set of instructions.

Key Takeaways

Missing your ex does not mean the relationship was healthy or sustainable.
Your mind may use happy memories to explain why the breakup hurts.
Fading Affect Bias can make positive memories feel stronger than negative ones.
Honeymoon-phase attachment and dopamine can intensify craving.
Regret and denial can make the past seem more fixable than it was.
You can honor what mattered without deciding you should go back.

Why Do I Always Think About the Good Times During a Breakup?

After a breakup, your memory is not necessarily giving you a balanced relationship review. It is offering emotionally charged fragments while your system is under stress.

Remembering love, laughter, chemistry, or companionship proves that the relationship contained good experiences. It does not prove the relationship was working.

Most relationships end because something important was not working, could not continue, or was no longer healthy. When happy memories move to the front of your mind, they can crowd out that context and create a story that feels more comforting than accurate.

There are five common reasons you may mostly remember the good times with your ex.

1. Your Brain Is Trying to Make Sense of the Pain

It can be deeply confusing to hurt over a relationship you know needed to end. Even when you understand the breakup was necessary, your body may react as though something essential has been taken from you. Your mind tries to make that contradiction feel logical.

It may tell you, “I must hurt this much because the relationship was wonderful.” From there, it is a short walk to “Maybe I should have tried harder” or “Maybe I made a terrible mistake.”

I experienced this after leaving a physically abusive relationship. Once the dust settled, I looked through photos and replayed our happiest memories: meeting for the first time, saying “I love you,” and traveling through Europe. I began turning the ending into a tragedy and wondering whether I should have done more to save us.

The relationship had not suddenly become safe. My memory had narrowed its focus.

This is why you may miss your ex even though the relationship was bad for you. Familiarity can feel like comfort, and losing what is familiar can hurt even when the loss is protective.

2. Fading Affect Bias Highlights the Positive

Fading affect bias describes the tendency for the emotional intensity attached to negative autobiographical memories to fade faster than the intensity attached to positive ones.

That can be useful. If every disappointment remained as sharp as it felt on the day it happened, moving forward would be much harder.

During a breakup, however, this process can make your ex and the relationship look better in retrospect. You still know the arguments happened. You know you felt lonely, dismissed, unsafe, incompatible, or exhausted. Yet those realities may not feel as immediate as the night you laughed together until two in the morning.

This is one reason you may romanticize your ex after a breakup. Your brain is not inventing the good memories, but it may be editing heavily—and grief is not famous for balanced storytelling.

Why Breakup Timing and Brain Chemistry Can Intensify the Memories

A short relationship can produce enormous grief, especially when it ends while the connection still feels new, exciting, and full of possibility.

3. The Honeymoon Phase and Dopamine Keep You Craving the Connection

During the honeymoon phase, people often experience infatuation, heightened sexual chemistry, intense focus, and a strong desire to spend time together. The relationship can feel exceptionally significant because so much of it is filtered through novelty and idealization.

This is also when people may notice red flags or incompatibilities and push them aside. If the breakup occurs during this stage, you may grieve both the relationship that existed and the future you imagined.

Dopamine can intensify that grief. When you become accustomed to the emotional reward of seeing, hearing from, or anticipating someone, their sudden absence can feel like a sharp drop. Looking at photos, rereading messages, checking social media, imagining a reunion, or reaching out may provide a small echo of that reward.

That helps explain why you cannot stop thinking about your ex after a breakup. Your system may be searching for familiarity and relief.

Craving the feeling does not mean the relationship should resume. It means you are attached and adjusting to change.

How Regret and Denial Rewrite the Relationship

Good memories become especially persuasive when paired with regret or denial. Both can pull your attention toward what the relationship might have been instead of what it consistently was.

4. Regret Makes the Past Look Fixable

Most breakups contain some regret. You may regret ending the relationship, not ending it sooner, communicating poorly, or failing to set firmer boundaries. Even when the breakup was necessary, you may wish parts of the ending had gone differently.

Regret becomes misleading when it presents imagined alternatives as guaranteed outcomes. You may convince yourself that one better conversation, one more attempt, or one different choice would have repaired everything.

Perhaps it would have changed something. That is not the same as knowing it would have created a healthy, lasting relationship.

Happy memories can intensify regret because they seem to prove there was something worth saving. There may have been. But “This mattered to me” and “This should have continued” are not the same conclusion.

5. Breakup Denial Protects You From Finality

In my breakup framework, I describe four stages: devastation, denial, realization, and release. They are not always neat or linear, but they help explain why people remain attached to a hopeful version of the past.

In denial, you may tell yourself the relationship can still work, should have worked, or would work if only one person changed. Good memories become evidence for the case, while recurring problems are treated like inconvenient technicalities.

Denial can feel easier than realization because realization requires accepting that the relationship is over. I understand why people resist that. I find the finality of relationships crushing, too.

But denial can keep you cycling through the same memories for months or years. Acceptance may hurt more sharply at first, but it creates movement. Denial preserves hope while quietly preserving pain.

Missing the Good Times Does Not Mean You Should Go Back

When you keep thinking about the good times during a breakup, your mind may be responding to pain, fading affect bias, dopamine, regret, or denial. None of those experiences means you are weak, foolish, or destined to reunite with your ex.

Healing begins when you can hold two truths at once: there were good times, and the relationship still ended for a reason. You can miss what was tender without returning to what was harmful, incompatible, or no longer right for you.

If you are struggling to separate what you miss from what was actually healthy for you, I would love to support you.
