Am I the asshole for wanting to turn in my highschool guidance counselor?

Back while I was in high school during my junior year my counselor(26) and I (17at the time) formed a tight bond between helping me with college applications and figuring out what I needed to do so I would be accepted into schools that had offered me a athletic scholarship. On the first day they announced the new faculty and they had said her name was the one responsible for my groups academic’s and social services. When I first met her I was taken aback by how well she had looked. It was like seeing transformers again for the first time. (Ifykyk) During the year we had grown close and started to have many off topic conversations and eventually started meeting for reasons not related to my academic’s at all. We were more less in a relationship without dating by October my junior year. We did a lot of relationship stuff Including going shopping a few towns over, having dinner together, we even started getting physical over winter break. We had met secretly at each other’s houses, in a Walmart parking lot, at my farm, or at a hotel on campus of a university close to us numerous times a week. As the year progressed she would FaceTime me while at the bar, after her husband left for work at night, including several times while nude. One night I’m driving with my friend and she FaceTimes me from the bar and says very nsfw things before realizing that my buddy was present then immediately she hung up. The very next day at school I was called to the office and disciplined for “talking to a teacher outside of school” and “continuing to attempt to reach out to her” after she had told me to leave her alone. I was very confused about this until I learned that she had self reported that I had reached out to her and that I wouldn’t leave her alone. She claimed that I had continued to call her untill she would pick up. Although I hadn’t said anything about our meeting’s I was under the assumption that they had known about it now. I never heard anything about her from that day forward except the next time I went to the office for help I had been placed under a different counselor’s direction.

Many years later now I realize the psychological & Emotional manipulation and grooming that took place im very conflicted about this but like half the town knows about it already and ive never been asked. I want to report it after my brother graduates this summer for his protection but I get mad the more I see her around. AITAH?
