Caught in the Moment

I was at a conference party when I got really caught up in the moment. My fiancé had left for a bit to chat with his advisor, and before I knew it, another attendee, let's call him Alex, started talking to me. We hit it off, and there was just this intense energy between us that night. I found myself laughing at all of his jokes, leaning in closer as the drinks kept flowing. He suggested we go for a walk outside, and... well, one thing led to another. It felt incredibly spontaneous and out-of-character for me; I’m usually pretty reserved when it comes to public displays or extra-marital anything. But with Alex, everything seemed different. We ended up sharing something intimate, hidden in the shadows of that party’s backyard. This isn’t just about an affair; it’s more like a momentary lapse of judgment fueled by the excitement and anonymity of being away from home. Since then, I’ve been ruminating over whether this was merely a one-off slip-up or if there might be something deeper at play here. Am I in denial about my feelings for someone other than my fiancé? Should we still go ahead with our plans to get married?
