The One Mistake I'll Never Forget

I'm an engineer, always thinking logically and methodically, so it's been really hard for me to come to terms with this one slip-up during a particularly difficult time at work. My partner was out of town on business, and I had these intense urges that just wouldn't go away. They were more than my open relationship could handle, they wanted something real, raw, and intimate in the moment. So, without really thinking it through, I reached out to an old flame, someone from college who I used to be close with but hadn’t seen in years. We met up at a hotel under the guise of catching up. The physicality was intense, we both knew there was nothing romantic lingering between us, just this primal urge to connect and feel alive for a moment. It’s been months now, and I still can't shake that feeling of loneliness even though everything's technically fine with my current relationship.
