Sorry this is long but don't want to drip feed. When I was in my late teens (16) one of my teachers at secondary school kissed and groped me (in school) but stopped when I asked him to. He was then sexually inappropriate with me on several other occasions, saying sexually suggestive things or trying to kiss/touch me again. When I rejected him clearly he became mean and cold toward me in a way that was obvious in my class. He was mid 40's then and the head of his department.
I also know for a fact that he was in a full sexual relationship with a girl from the year above me when she around 15, it was common knowledge in my friendship group. This teacher taught an arts subject and was very popular with his students, although most of the adults I knew didn't like him. In retrospect I think some of his behaviour could be described as grooming, he would drink with us, let us smoke and drink in his flat and on school trips and asked us to confide in him. He ran 'experimental' workshops in the art form he taught, which required teenage students to access and express 'deep' emotions. At the time they seemed important and meaningful but in retrospect it was irresponsible and dangerous, he had no psychological training and there were no boundaries.
I didn't tell anyone at the time because I was 16 and I was embarrassed and ashamed. I'm now in my mid-thirties with kids of my own and I know he is still teaching teenagers (he is in touch with some of my old school friends on Facebook).
I told a friend who I went to school with and she remembers what happened in his 'workshops' and what happened with the girl in the year above mine. We went together to our old school and reported what happened to the current CEO (it's a private international school in another country). He was helpful and took me seriously, he explained that the school had no child protection policy at that time and that it does now. He said that there is no 'governing body' for international schools and there is no clear channel to escalate this. He did offer to call the head of this teacher's current school (which is in a third country) and report what I had told him, he did this but I have no idea how seriously the head of the current school took this. My old teacher is still in his role. I reached out to the girl from the year above mine and asked if she would back me up but she does not want to be involved and would rather simply forget the whole thing happened. Without her voice it's just me and its difficult to evidence there was grooming (which is what really worries me I think).
The truth is this bothers me but didn't affect my life in any tangible way, I don't feel traumatised, just creeped out. I do, however, feel worried about teenage girls who are in his care now, guilty for not saying something sooner and guilty for letting it go (which I would really like to do - I just don't see what other avenue I can pursue here). The teacher is English but living and working abroad, teaching at another international school in a senior position. Finally, he is now married with children (he wasn't when he taught me) and I feel guilty about the potential disruption and trauma this could cause his kids if he lost his job. AIBU to think I've done all I can?
