This story hit me hard. Though I wasn't groomed by any teachers, I was stalked by a former psychology professor in college and almost dropped out because of safety concerns. https://slate.com/human-interest/2021/04/blake-bailey-former-student-sexual-assault-essay.html
He would show up to my work and just stare at me. He knew my class schedule and would corner me in the halls. He knew my car and would walk in to wherever I was (bar, venue, etc.) and just sit, alone, watching me. He would send me FB messages that over time got longer/creepier.
When my dad called him to tell him to stop harassing me, he answered, "I know exactly what I'm doing" and hung up. I took him to court and lost. Soon after, his wife divorced him and he lost his job. I feared for my life.
A few years later, he showed up to a gig of mine while I was on tour in a completely different city. He continued to harass me via social media/email with new, unblocked usernames/addresses.
I'm still scared of him and don't post personal info. online because he or another stalker/abuser I've had (there have been a few unfortunately) might see it.
This situation is way too common and I feel for anyone thinking they didn't handle their assault the "right" way. It's a confusing thing to be harassed by someone who is supposed to protect/nurture you; it's shattering to know that rarely anything comes of reporting it.
