Why Siblings Stop Talking: The Real Reasons Behind Family Estrangement

Nearly 1 in 4 adults have experienced a period of estrangement from a sibling — and it's more common (and more complicated) than most of us realize. In this episode of MissPerceived, Professor Leah Ruppanner unpacks a new study out of Ohio State University that dug into 39 in-depth interviews to understand why adult siblings go no contact.

Leah breaks down the two major forces driving estrangement: parental behavior (favoritism, manipulation, and forcing siblings to "pick sides" after a parent-child conflict) and the sibling relationship itself (destabilizing conduct, safety threats, and childhood bonds that were never really built). She shares personal stories from friends navigating estrangement, explains the concept of family systems and triangulation, and connects all of it back to the mental load — the emotional scanning, relationship repair work, and guilt that estranged (or nearly estranged) families create.

If you've ever felt like your family "doesn't understand your world," or you're carrying guilt about a sibling relationship that isn't what it's supposed to be, this episode offers real permission to step back, set boundaries, and stop measuring your worth by an outdated obligation to stay close no matter what.
