A Secret Night Out

I was married for ten years when I decided to go out one night just for me. It wasn't a big deal, really, just drinks with friends and some flirting that went further than it should have. I knew what we were doing was wrong the moment our lips met, but there was something so freeing about it, so different from my marriage's routines. I've been keeping this to myself ever since, terrified of how my wife would react if she found out. It's a secret that eats at me every day.
