I walked into the funeral feeling numb. Ten years had passed since I cut ties with my twin sister, Lily. We were inseparable once — two halves of the same soul — until the night I found her kissing my fiancé. I didn’t yell or fight; I simply walked away and built a wall she never managed to climb. She tried to explain, to apologize, but I couldn’t forgive what felt like the deepest betrayal.

Now, at 29, I stood there watching strangers mourn my sister more than I ever had. The memories of childhood laughter clashed with years of silence. I felt guilty, not for what she did, but for how much space resentment had taken in my heart. When it was over, my mom begged me to visit Lily’s room one last time. Hesitant but curious, I agreed.

Inside, everything was frozen in time — neat shelves, soft colors, and photos of us as little girls taped to her mirror. That alone made my throat tighten. Then I noticed a folder with my name on it. Nervous hands opened it. Inside were letters she had written to me over the years and never sent. Page after page filled with apologies, memories, and hopes that one day we would be sisters again. She wrote that she regretted everything and loved me more than anything in the world.

Tears finally fell. All the anger I carried dissolved into quiet grief. I sat on her bed, clutching the letters, realizing forgiveness isn’t for the other person — it’s for the part of us that still aches. I whispered an apology to the empty room, promising to remember her not for the mistake she made, but for the sister she was before it all went wrong. And in that moment, I finally let her go — and freed a part of myself too.
