You've probably seen those two words everywhere lately. Tattoos on forearms, aesthetic Instagram reels, and definitely on your TikTok FYP. Maybe you first heard it from Mel Robbins, who basically built a whole "theory" around it. But if you dig just a little deeper, you’ll find the real heartbeat of this movement isn’t in a $30 hardcover book. It’s in a raw, simple piece of writing known as the Cassie Phillips poem Let Them.
Honestly, the story of how this poem went from a viral snippet to a global mantra is kinda wild. It’s a mix of soul-searching, internet drama, and a very human struggle to just... stop caring so much about what everyone else is doing.
Who Is Cassie Phillips and Where Did This Poem Come From?
Cassie Phillips isn't some high-flying corporate motivational speaker. She’s a writer and a mental health advocate who started sharing her journey online around 2020. She’s been pretty open about the fact that her writing comes from a place of healing—specifically after dealing with abuse and "inner-child wounds."

The Cassie Phillips poem Let Them actually started gaining serious traction around September 2022. It wasn't an overnight thing, but once it hit, it hit hard. People started sharing it in therapy groups, domestic violence support circles, and breakup forums.
One thing Cassie always points out is that she didn't "invent" the concept of letting go. She’s mentioned being inspired by Tyler Perry’s Madea character—specifically that famous speech about people being like leaves on a tree. If they want to go, let them go. But Cassie took that sentiment and turned it into a rhythmic, almost liturgical poem that feels like a big, deep breath.
The Words That Started a Movement
If you haven’t read the full text of the Cassie Phillips poem Let Them, it hits differently when you see it all at once. It’s not just about being passive. It’s about self-preservation.
"If they want to choose something or someone over you, LET THEM.
If they want to go weeks without talking to you, LET THEM.
If they are okay with never seeing you, LET THEM.
If they are okay with always putting themselves first, LET THEM."
The poem continues with this relentless "Let Them" cadence. It covers being misunderstood, being judged, and being left behind. The pivot point—the part that usually makes people start crying—is the line: "Let them lose you. You were never theirs because you were always your own."
It’s a brutal kind of freedom.
Why the Poem Is Different From the "Theory"
There’s been a lot of heat online regarding Mel Robbins and her book The Let Them Theory. If you’ve been following the drama on Reddit or YouTube, you know the timeline is a bit messy. Mel’s team allegedly shared Cassie’s poem in 2023, and then by 2024, the "Theory" was a bestselling book.
Mel claims the idea came to her through a personal moment with her daughter, but for thousands of people who already had the words of the Cassie Phillips poem Let Them tattooed on their skin, the "discovery" felt a bit late to the party.
The difference is mostly in the vibe. The poem is art; the theory is a system. Cassie’s work is about the emotional release of realizing you aren't responsible for someone else's bad behavior. It’s about the "Let Me" and "Let You" that follows.
The Philosophy of Letting Go (Without Losing Your Mind)
Let's be real: "Letting them" is incredibly hard. It feels like giving up. We’re taught to fight for what we love, to communicate until we’re blue in the face, and to "fix" relationships.

But Cassie’s poem suggests a different path. It’s about the "gap."
- The Gap Between Words and Actions: If someone says they love you but treats you like an option, let them show you who they really are.
- The End of Micromanagement: You can’t control if your friend is gossiping about you. You can’t control if your ex is dating someone new. You can control how much energy you leak trying to stop it.
- The "Open Door" Policy: Cassie writes about holding the door open for people who want to leave. It’s a power move, honestly. It says, "My life is a high-vibration space, and if you don't want to be here, I won't beg."
Common Misconceptions About the Poem
A lot of people think the Cassie Phillips poem Let Them is about being a doormat. Like, "Oh, they're cheating on me? Let them."
No. That’s not it at all.
Actually, it’s the opposite. It’s about setting a boundary so firm that you don't even have to argue about it. If someone chooses to disrespect you, you "let them" do it over there, away from you. It’s about realizing that you don't need to attend every argument you're invited to.
Some critics, like those in certain Christian circles, argue the poem is too "self-focused" or "victim-heavy." They suggest we should focus on "Him" rather than "us." But for many survivors of toxic relationships, reclaiming "themselves" is the first step toward any kind of spiritual or emotional health. You can’t give from an empty cup, right?
How to Actually Use This in Real Life
So, how do you actually "let them" when your heart is racing and you want to send a 10-paragraph text?
It starts small.
Maybe your coworker takes credit for your idea. You could spend the afternoon fuming and plotting a passive-aggressive email. Or, you could let them be the kind of person who needs to steal ideas to feel important. Their character is now visible to everyone. You keep your peace.
Maybe your mom is judging your parenting again. Let her have her opinion. It doesn't change your reality unless you let it.
Cassie’s follow-up work, Let You, is really the second half of the equation. Once you let them be who they are, you finally have the space to let you be who you are.

Actionable Steps to Reclaim Your Peace
If the Cassie Phillips poem Let Them resonated with you, don't just read it and scroll past. Try these steps today:
- Identify the "Leaky" Relationship: Pick one person who is currently draining your mental energy. Are you trying to change them? Are you waiting for an apology that isn't coming?
- The 24-Hour Silence: The next time someone "does them" (misunderstands you, leaves you on read, makes a choice you hate), wait 24 hours before responding. Just let them exist in that choice without your interference.
- Audit Your "Control" List: Write down things you’re stressed about. Cross out anything that involves another person’s choices. You’re left with your reactions. That’s your only job.
- Support the Source: If you love the poem, check out Cassie’s actual platforms. She’s built a community focused on "The Let Them Story," and hearing it from the person who lived the words usually carries more weight than a polished marketing campaign.
Ultimately, "letting them" isn't about them at all. It’s about you. It’s about the moment you realize that your peace of mind is way too expensive to be bought and sold by the whims of people who don't even know their own hearts.
Hold the door open. Take a breath. Let them.
