A week before Christmas, I heard my son say, “Just dump all nine kids on her.” On December 24, he called: “Where are you?” I said, “Don’t wait for me—or the gifts, or the catering I paid for.”

I drove past the ragged edge of Tucson just as the sun hit its zenith, the harsh light catching the hood of my car in a brilliant flash. I didn’t turn on the radio. The silence inside the cabin was a thick, luxurious blanket. I hadn’t experienced true silence in years. My life had been a cacophony of cartoon theme songs, ringing cell phones, and the sharp demands of adults who still acted like children.

Somewhere past Deming, I pulled over at a dusty gas station. I took my phone out of the cup holder. Six missed calls from Logan. Three from Emily. One from Maria. I stared at the glowing notifications, a deep, hollow canyon opening behind my ribs.

My mind betrayed me, dragging up a memory from twenty years ago. Logan was eight years old. I had been bedridden with a terrible flu. He had crept into my darkened bedroom on a Sunday morning, his small hands carefully balancing my favorite chipped ceramic mug. He had made me tea—lukewarm tap water mixed with entirely too much honey. “Careful, Mom,” he had whispered, his face flushed with fierce pride. “It’s really hot.” I had pulled him under the heavy quilt, letting him fall back asleep against my ribs, overwhelmed by the pure, uncomplicated love radiating from his small body.

That boy felt like a ghost. He felt like someone I used to know in a previous lifetime. Somewhere along the grueling road of adulthood, his warmth had calcified into assumption. He had stopped asking for favors and started handing me heavy obligations, neatly wrapped in polite packaging. I pressed my forehead against the cold steering wheel. When, exactly, did I stop being someone he looked up to, and become someone he merely leaned his entire weight against without ever bothering to look back?

Maybe the pattern had always been there. Soft, dismissive comments I had brushed off. Disrespectful choices I had let slide because I foolishly believed that unconditional love required infinite flexibility. I still loved my son. That biological tether was unbreakable. But staring out at the rust-colored mesas rising in the distance, I was finally beginning to understand that love does not require you to offer yourself up as a human sacrifice every time someone else refuses to carry their own weight.

I powered the phone completely off. No silent mode. No vibration. I shoved it deep into the glove compartment and slammed it shut. I didn’t want to decipher anyone’s passive-aggressive texts. I just wanted the road.

By the time I crossed the state line, the sky had bruised into a pale, brilliant gold. I had a few more hours until I reached the coordinates Nadine had sent me. I didn’t need a GPS anymore. I just needed to keep moving forward.
