KC Davis is a therapist and author known for her practical, empathetic advice on dealing with clutter, even when you are feeling like too much of a mess yourself to take care of the mess in your home. Her TikTok videos on the subject have been viewed millions of times. But lately, Davis has been talking and writing about our relationships not just to the objects in our lives, but to the people, too.

In her new book, “Who Deserves Your Love: How to Create Boundaries to Start, Strengthen, or End Any Relationship,” Davis tries to disentangle the popular understanding of boundaries, saying the concept is widely misunderstood. She offers a guide to forming and keeping boundaries that help readers better navigate their conflicts with other people.

On this episode of “Modern Love," Davis tells us what she thinks we get wrong about boundaries and how we should be thinking about them instead. She reads the Modern Love essay “Is My Husband a Doormat?” about a sudden argument between a couple 20 years into their relationship and talks about how boundaries can help defuse such situations. Davis also tells us how boundaries helped heal her own relationship with her father.

The author of today’s featured essay, Lidija Hilje, has a new novel coming out in July called “Slanting Towards the Sea.“

For an upcoming episode about location sharing, the Modern Love team wants to hear your location-sharing story. Did something happen that made you regret sharing your location with someone? Was there a moment when you were thankful that you had? Where were you? What happened? How did your relationship change as a result? The deadline is May 1. Submission instructions are here.
