Lending my boyfriend to my best friend

There are people who enter your life like seasons. Some arrive quietly, bringing warmth you never knew you needed. Others become home before you even realize you've stopped looking for one. Georgia was home. If someone had asked me when we were seven years old, sitting beneath the old acacia tree behind our elementary school, what forever looked like, I would've pointed at the two of us sharing a melted popsicle and laughing over absolutely nothing. Forever looked like scraped knees after racing bicycles. It sounded like whispered secrets during sleepovers. It smelled like old books from the town library and rain-soaked afternoons. Forever was Georgia. Back then, I believed the world was kind enough to let children keep the promises they made. "I'll never leave you." "I'll always tell you everything." "We'll grow old together." Children never know that life has a cruel sense of humor. At sixteen, I broke every promise I'd ever made. I left without telling her the truth. Not because I didn't trust her. Not because I stopped loving her. But because I loved her too much. The doctors called it by a name that sounded too complicated for someone my age. They spoke about percentages, treatments, side effects, and possibilities. My parents spoke in hopeful smiles that disappeared the moment they thought I wasn't looking. So we left. Everyone believed it was because Dad had been promoted overseas. Everyone except me. I knew we were leaving because my life had suddenly become measured in hospital rooms instead of birthdays. Three years. Three years of needles. Three years of white walls. Three years of wondering if I'd ever see home again. And somehow... I did. When our plane landed, all I wanted was to find the girl I'd left behind and pretend that none of it had ever happened. I wanted one more summer. One more birthday. One more late-night walk. One more memory where I wasn't the sick girl everyone pitied. I promised myself I would never tell Georgia. Not because I wanted to lie. Because I wanted her to remember me laughing instead of fading. I thought keeping my secret would protect her. I never imagined it would destroy all three of us. Because I didn't expect to fall in love with the one person who had spent years loving her. And I definitely didn't expect time to run out before I could make things right. If I had known how our story would end... I would've hugged her a little longer the day I came back. Maybe forever isn't about staying. Maybe it's about leaving enough love behind that someone carries it for the rest of their life. My name is Cassandra. This is the story of how I borrowed my boyfriend from my best friend... ...and how love became the goodbye I never wanted to say.
