The "Let Them Theory": A Therapist's Perspective on When It Helps, and When It Doesn't
The "Let Them Theory": A Therapist's Perspective on When It Helps, and When It Doesn't
Written by Lily Thrope, LCSW
If you've spent any time on TikTok, Instagram, or podcasts recently, you've probably heard someone say: "Let them."
Someone doesn't text you back? Let them.
Someone judges you? Let them.
Someone doesn't invite you? Let them.
The idea, popularized by Mel Robbins, has become one of the biggest mental health conversations online because it offers something many of us desperately want: relief from constantly worrying about what everyone else thinks.
As a therapist, I actually think there's a lot to like about the "Let Them Theory."
But like most viral mental health advice, it's only helpful when it's applied thoughtfully.
The reality is that healing isn't about ignoring your emotions or pretending you don't care. It's about learning what you can control, what you can't, and how to respond in ways that support your well-being.
Let's break it down.
What Is the "Let Them Theory"?
At its core, the Let Them Theory encourages people to stop trying to control other people's behaviors, opinions, or decisions.
Instead of convincing someone to like you...
Instead of obsessing over why they acted a certain way...
Instead of trying to manage everyone's reactions...
You simply let them.
This mindset shifts your energy away from controlling others and back toward yourself.
For many people, that can feel incredibly freeing.
Why the Let Them Theory Can Be Good for Your Mental Health
It Reduces Anxiety
Many people struggle with anxiety because they're constantly scanning for signs that they've done something wrong.
"Did I upset them?"
"Should I have said something differently?"
"Why haven't they responded yet?"
The Let Them Theory reminds us that we can't control how another person thinks, feels, or behaves.
Accepting that can reduce rumination and free up emotional energy for things that actually matter.
It Encourages Healthier Boundaries
Sometimes we spend enormous amounts of time trying to convince people to respect us.
The truth is: healthy relationships don't require constant convincing.
If someone repeatedly ignores your needs, disrespects your boundaries, or refuses to meet you halfway, the healthiest response may not be trying harder.
Sometimes it's allowing people to show you who they are—and making decisions based on that information.
It Builds Self-Trust
Many people are used to looking outside themselves for reassurance.
The Let Them Theory encourages asking a different question: "What do I need right now?"
Over time, this builds confidence in your own judgment rather than relying on external validation.
When the Let Them Theory Isn't Enough
This is where therapy often adds nuance.
There are situations where "letting them" isn't the healthiest response.
When you're avoiding difficult conversations
Maybe your partner hurt your feelings.
Maybe a friend crossed a boundary.
Maybe a coworker repeatedly takes credit for your work.
"Letting them" doesn't mean staying silent.
Healthy relationships require communication.
Speaking up about your needs is not controlling someone. It's advocating for yourself.
When You're In a Toxic or Abusive relationship
The Let Them Theory should never be used to tolerate emotional abuse, manipulation, or unsafe situations.
If someone continually harms you, the answer isn't simply "let them."
The answer is creating boundaries, seeking support, and prioritizing your safety.
When You're Using it to Avoid Your Own Emotions
Sometimes people interpret "Let them" as:
"I shouldn't care."
"I shouldn't be upset."
"I need to move on immediately."
But emotional healing doesn't work that way.
You can let someone make their own choices while still feeling disappointed, hurt, angry, or sad.
Your feelings deserve attention.
Ignoring them doesn't make them disappear.
Healthy Detachment vs. Emotional Shutdown
One of the biggest misunderstandings about the Let Them Theory is confusing acceptance with emotional numbing.
Healthy detachment sounds like:
"I can't control what they choose."
"I'm disappointed, but I'll take care of myself."
"Their behavior doesn't define my worth."
Emotional shutdown sounds like:
"I don't need anyone."
"I won't let people get close."
"I just won't care anymore."
These are very different.
Healing isn't becoming emotionally unavailable.
Healing is staying open while accepting that you cannot control other people.
What About People-Pleasing?
For people who struggle with people-pleasing, the Let Them Theory can be incredibly helpful.
If you've spent years trying to make everyone happy, this mindset can help you realize that:
Not everyone will approve of you.
You don't have to earn your worth.
Other people's disappointment isn't always your responsibility.
However, if your people-pleasing developed because of trauma or chronic anxiety, "just let them" may not feel that simple. Your nervous system may interpret conflict or rejection as a threat rather than an inconvenience. In those cases, healing often requires more than a mindset shift. It requires understanding where those patterns came from and learning new ways to respond.
The Let Them Theory and Eating Disorder Recovery
This mindset can also be valuable during eating disorder recovery.
Many people in recovery worry about:
What others think they're eating.
Comments about weight or body changes.
Family opinions.
Social pressure around food.
Being judged for recovery choices.
Recovery often means allowing people to have their opinions without letting those opinions dictate your decisions.
You can let someone misunderstand your recovery.
You can let someone disagree with your boundaries.
You can let someone have their own beliefs while continuing to choose behaviors that support your health.
That doesn't mean those comments won't hurt.
It means their opinions don't get to decide how you care for yourself.
How to Use the Let Them Theory in a Healthy Way
The healthiest version of this mindset isn't passive. It's intentional.
The next time you find yourself spiraling over someone else's behavior, ask yourself:
Is this something I can actually control?
Do I need to communicate a boundary?
Am I trying to change someone else's choices?
What would taking care of myself look like right now?
Sometimes the answer is letting them.
Sometimes the answer is having a difficult conversation.
Sometimes it's walking away.
And sometimes it's allowing yourself to feel exactly what you're feeling before deciding what comes next.
Final Thoughts
The Let Them Theory isn't about becoming indifferent.
It's about recognizing that peace comes from releasing the need to control what isn't yours to control.
As a therapist, I see this mindset become most powerful when it's paired with emotional awareness, healthy boundaries, and self-compassion.
Because real healing isn't about pretending you don't care.
It's about caring for yourself enough to stop carrying responsibilities that were never yours in the first place.
If you are reading this and any part of it resonated, the early dieting, the athlete who was always restricting, the high-functioning person who was quietly falling apart, I want you to know that it does not have to stay that way. Recovery is not reserved for people whose stories look a certain way.
You are allowed to get help for exactly what you are experiencing right now.
