Bruh, I had a similar experience (that thankfully went nowhere). I'm rounding 40 in a few years, but was 33ish at the time. Incredibly hot, fun, smart 22 year old, fresh out of college started working in my group.
Long story short -we totally click on every level. Go out a few times after work with other people from work (happy hour). I'm thinking to myself that my marriage is going to be over at this point; I'm totally going to end up not being in control and cheating on my wife and fucking up my family. I don't know how I ended up telling myself this was a pure ego thing where I was attempting to see if "I still got it", but I did.
She made a move and told me she was falling for me. I told her that despite having a massive crush on her, I realized after objectively assessing the situation, it was just a crush and I love my wife and family. She was literally over me in a week. Once I stopped with the goo-goo eyes, it slowly started coming out that she was in fact, still an immature kid. She banged like 3 dudes around work and was not shy about dropping me details about the events, there were issues with her and other female co-workers, her workplace demeanor was very unprofessional.
