Do Dismissive Avoidants Obsess Over Exes? What Studies Show

The idea that dismissive avoidants secretly obsess over their exes is widespread online, but psychological research tells a very different story — one that matters if you’re trying to reconnect with a dismissive avoidant.

When relationships end, not everyone experiences lingering thoughts about an ex. While many people replay old moments and wonder “what if?” long after a breakup, individuals with a dismissive avoidant attachment style typically do not engage in obsessive thinking about former partners. Instead, research consistently shows that dismissive avoidant attachment predicts emotional deactivation and psychological distancing, rather than rumination or prolonged focus on a lost relationship.

Avoidant attachment & post breakup rumination

One of the best documented findings linking lower distress and rumination after relationship dissolution is by Marshall, Bejanyan & Ferenczi (2013) — PLoS ONE

This large study measured adult attachment styles, breakup distress, rumination, and rebound behaviours after romantic dissolution. Results showed:

Attachment avoidance was associated with inhibited breakup distress — meaning avoidant individuals showed less emotional upset and less reflective thinking about the end of the relationship.

In other words, the very emotional intensity and cognitive engagement (e.g., ruminative thinking) that characterizes post breakup obsession in anxious individuals is suppressed in dismissive avoidants.

Why avoidants don’t obsess: mechanisms from psychology

This study is consistent with the core feature of a dismissive avoidant attachment style. Psychological studies show that a dismissive avoidant attachment isn’t associated with obsessive focus on lost relationships but with emotional disengagement and cognitive distancing.

Individuals high in avoidant attachment are more likely to:

• Experience less breakup distress
• Avoid thinking about their ex
• Use distraction and suppression to cope rather than reflection and rumination
• Rebound or move on without lingering preoccupation

Where the misconception that “dismissive avoidants obsess over their exes” comes from

Even though the science is clear that dismissive avoidants do NOT ruminate or obsess (Marshall et al., 2013; Saffrey & Ehrenberg, 2007), the internet narrative often claims the opposite.

Here are the specific sources of the misconception:

1. Confusing “regret” with obsession

Dismissive avoidants experience regret and moments of missing their ex. But these moments are:

• Short, episodic, and compartmentalized
• Triggered by specific cues (hearing from or seeing an ex, memories, a life transition)

But they NOT followed by rumination, pursuit or obsession.

People mistake these brief moments of vulnerability for “obsessing,” when in reality they’re normal flashes of emotional vulnerability not obsessive thinking loops.

2. Dismissive avoidants get lumped into the same category as fearful avoidants

On social media, “avoidant” is used as one umbrella term. But fearful avoidants (FA) and dismissive avoidants (DA) behave differently:

Because fearful avoidants (anxious avoidants) sometimes obsess over exes (due to being part anxious attachment), people assume dismissive avoidants are the same. So the misconception spreads through category confusion.

3. Social media algorithms reward “hope content”

On TikTok, YouTube, and Reddit, the most viral content is:

• “Your avoidant ex secretly misses you!”
• “Avoidants obsess over you in no contact!”

This content:

• Feeds hope
• Keeps viewers emotionally engaged
• Drives clicks

It’s not based on research — it’s based on audience retention. The real science says the opposite:

• Attachment anxiety — rumination, obsessive thinking (Marshall, Bejanyan & Ferenczi, 2013)
• Attachment avoidance — emotional suppression, reduced rumination (Saffrey & Ehrenberg, 2007)

But “they don’t obsess” doesn’t go viral.

4. Observing avoidant behaviour incorrectly through an anxious lens

People with anxious attachment:

• Obsess
• Ruminate
• Monitor their ex
• Replay conversations for months

So when their dismissive avoidant ex acts distant or disappears, the anxious person assumes: “If I can’t stop thinking about them, they must be thinking about me too.”

This is emotional projection, not reality. In reality, dismissive avoidants are using deactivation — reducing emotional arousal by avoiding thoughts altogether (Fraley & Shaver, 2000).

5. Misreading the “avoidant recycling back to exes pattern”

Dismissive avoidants sometimes return after a breakup not due to obsession, but because:

• Distance lowers their internal stress
• Autonomy is restored
• The threat of intimacy disappears

This creates openness to reconnection. People mistake this for: “They were secretly thinking about me nonstop.” But research shows dismissive avoidants reach out because they feel safe doing do, not because of ongoing rumination (Fraley & Shaver, 1997; Simpson & Rholes, 2010).

They’re not obsessing, they’re resetting after regulation.

6. Mixing up behaviours: obsessive actions vs. obsessive thoughts

Occasionally, a dismissive avoidant might:

• Check social media once
• Suddenly add an ex on social media
• Ask a friend how you’re doing
• Reach out of nowhere

These behaviors are not the same as obsessive cognition. These are compartmentalized and fleeting, not days-long mental spirals.

The scientific literature is extremely consistent: Dismissive avoidants do not obsess, ruminate, or fixate on an ex after a breakup.

What this means for you if you’re trying to reconnect with a dismissive avoidant ex?

It means you can’t rely on your avoidant ex “missing you” or ruminating to pull them back in. They’re not wired to replay the relationship in their mind or chase unresolved feelings, so reconnecting depends more on present-moment experiences than nostalgia or regret.

This also means that consistent, low-pressure contact matters far more than waiting for them to reach out.
