Feeling Screwed

I worked for 5 years as a property manager for a global company. About a year an ago, my HR manager began to openly flirt with me. In the beginning, it was flattering and kind of exciting. I knew she was doing extra work for me and putting my concerns above other people. She became more aggressive and started to insist on meeting me and having sex. I didn’t want that but it I started to worry what she could do if I upset her. I stalled. I still to this day have never met her. I kept kicking the can down the road saying the timing wasn’t right. She kept calling, morning and night. She kept sending pictures. I have over 100 and many are naked including a few videos. I did talk to her a lot and I kept making excuses not to meet and stalling while still trying to keep her from turning on me because, I need her to do my job. She was responsible for running background checks and onboarding my employees. About a month ago, she began to pull away and not communicate with me the same way. Of course she was also getting very slow to process the work tasks that I was counting on to do my job. When I brought up her lack of communication she proceeded to explain to me that she was in love with me and I hurt her by never meeting her and she realized she couldn’t have me. I got very uncomfortable and resigned a week later.
