i let my coworker seduce me in an empty patient room

hey so this happened a few weeks back. i was working the late shift and everything was super quiet. my co nurse, sarah, came on her nightshift too. we've worked together for ages and yeah things have always been kinda friendly but nothing ever crossed that line. anyway she's in her early 40s too just like me. one day she starts telling me about how stressed out she is at home with her kids and stuff, really opened up to me which was nice i guess? we've never had this kind of real conversation before. so then later that night it was super late and there were no patients in the room near us so i offered to help sarah take a break for some fresh air. she said come on lets go into the patient room instead, it's more private. weird right? but i went along with it. once inside she just started telling me how much she wants out of her marriage and how beautiful she thinks i am and stuff like that... i was so confused and nervous but also flattered? then before i knew it we were kissing on the exam table, touching each other everywhere. we ended up having wild hot sex right there in the patient room, fully dressed, just fucking each other like bitches. i left afterward feeling super messed up inside but couldn't bring myself to tell my husband about it or say anything to sarah at work. i've been so lost with how i feel since then. i'm such a mess.
