I Broke My Own Rules

I never thought I'd end up like this. Met someone online who was completely different from anyone else in my life. We talked for weeks before we agreed to meet. It happened so fast, one thing led to another, and we did something that went against everything I believed in. Afterwards, I felt sick with myself but couldn't stop thinking about it. It's been months now, and still, every time I think about what we did, a chill runs down my spine.
