I Told My Best Friend I Loved Her

We'd been friends for twelve years. She was getting married next month. I stood in her kitchen while she showed me wedding invitation samples, and I just said it. 'I've been in love with you since college.' She froze. The invitations slipped from her hand and scattered on the floor. She didn't say anything for what felt like hours. Then she said, 'I know.' And she walked out. We haven't spoken since. I don't regret telling her. I regret waiting until it was too late.
