<human>: Where do I begin...

I have a fiancee, and a baby on the way. However there is this woman who was hardcore flirting with me at work, but I didn't shut her down right away. She asked me out to the movies and I obliged. We ended up kissing, and I'm having MAJOR regrets. After a long fight with my fiancee, after telling her in the matter of a few hours because I felt so bad, I realized I had another big predicament on my hands. Work. I have a feeling that she is a huge gossiper because my work place is filled with teens. How do I avoid getting fired from work? Should I even go to work tomorrow? Should I just deny everything if it's brought up? WAT DO REDDIT?

Give me a shortened version of the text
<bot>: I am engaged. Kissed a co-worker outside of work. She gossips. How do I not get fired?
