I messed up and fucked a new coworker. She flew in for training and will be leaving soon but we went out yesterday and fucked last night a bit. I did check in and ask at the beginning if being unprofessional is fine outside of work and she agreed and affirmed I wasn’t crossing boundaries. This morning I of course said good morning and had a great time.. stuff like that and would like to see her again today. She said she wasn’t feeling well and now hasn’t responded to any messages. Last night seemed great for both of us and I’m just kicking myself now because of feeling empty. I know I played with fire from a career standpoint but I couldn’t resist at the time. I hate myself now. Especially since she is ignoring me.
