9 months of relationship ended

I started seeing a woman who was initially my boss. After a team night out, we had an affair in a hotel room. She idolized me for three months. Then one night, while she was smoking, I became distant and frustrated because I kept asking her to stop. She felt abandoned and split.
She created a BDSM profile and started dating others. I discovered her profile with photos and videos of her drinking piss. She then went back to her narcissistic ex. The morning I told her I loved her, she had slept with him the night before. When I found out, I went no contact. She hoovered me after two weeks. After 30 days, we had an amazing date and agreed to date officially.
I later found herpes medication in her bag. She hadn’t told me. When I confronted her, she admitted that a BDSM date from three months earlier had raped her in her sleep, and she contracted anal herpes.
After one month of officially dating, her ex went no contact because she chose me. After two months, her behavior changed. I had become very involved in her life, playing Fortnite with her son and seeing her multiple times a week. She grew distant. I asked her to stop the push-pull, but she doubled down and stopped kissing me.
On Saturday, she devalued me by comparing my physique to another guy’s, saying he was more in shape. She invited a man to sit with us at a show, talked with him all night, and then texted him later, while still with me, inviting him out for drinks. He replied that his girlfriend wouldn’t like it. I exploded, told her she had sabotaged the relationship, and that ot was over. I said I had been the most positive person in her life this year. I deleted her on Instagram and left.
Today I feel lost. I know we’re both codependent. She doesn’t make me happy and isn’t emotionally healthy, but letting go is incredibly hard.
