Was She The Love Of My Life?

I will start this out by saying I have been happily married for just shy of 24 years. There was a time in 2009 when I was a manager at a gas station and I needed to hire a new employee. I did interviews and ended up hiring a younger female. Even though she was beautiful and attractive I hired her for her abilities. I trained her to open the gas station and was training her for awhile. After a short time I would pick her up at her house and drive her to work since she was having car issues at the time. We seemed to get closer and closer and I believe she was attracted to me as I was attracted to her. Side note she was also in a relationship with her boyfriend and she has a kid. Anyways we worked together every day me as the manager in charge of the gas station and her as the employee. Over time we would constantly flirt with each other. A little later on she dared me to kiss her. After some time thinking about it I did kiss her away from the cameras at work. Over time kissing escalated to more including passionate kissing and touching each others bodies. Over time this became a full fledge affair. We would constantly text each other and would write each other notes at work expressing our feelings and love for each other. We ended doing much more at work over the next few months. I truly believe I was in love with her. She gave me butterflies in my stomach when I was with her. Never before in my marriage or life had I ever cheated on anyone. This girl too was 10 years younger then me. We were very attracted to each other and did many things even my wife and I ever did. This girl just knew perfectly how to make me feel good and happy. And I believe I did the same for her. Unfortunately this ended and I moved out of state to take on a new job. But to this day 15 years later I still think about her all the time and wish I could have had just one more day with her. I do have guilt over this and no one has ever found out any of this.
