Caught Off Guard

I never thought I'd be here, confessing this after all these years of marriage. It happened a few weeks into our separation when I was trying to figure everything out. One night, feeling lost and lonely, I ended up at an upscale bar where I met someone charming, much younger than me. We talked for hours, had drinks, and before I knew it... well, you can guess. We went back to his place, and there we were, two adults sharing something neither of us expected. It felt both thrilling and terribly wrong, knowing full well what I was doing. How could this have happened? I feel like such a fraud.
