It is very common for autistic people to
be manipulated particularly at school as some other children and teens will know their triggers and deliberately manipulate them into a meltdown (sometimes known as wind them up and see them go!)
I used to teach autistic teens and both nt and nd teens would do this - often particularly if I was teaching a topic that they didn’t want to learn or they just wanted a distraction.
it gets less and less usual as the teens mature.
on the healthy relationships front, many autistic teens have to be taken out of the RSE education in schools because it is fundamentally about how to recognise abuse and some more aware autistic teens begin to understand that when they meltdown they are abusive.
this is usually not productive as it generally means that as well as having meltdowns they then afterwards have a massive burden of shame - thinking eg physical abuse is bad, I’m a bad person, nobody will ever want to be my friend, I’ll never have a partner etc.
so it’s actually not a good idea at this point in time to expose him to this as it will lead up increased anxiety and possible self harm after meltdowns which frankly isn’t helpful.
most perpetrator programmes are intended for nt people and are not appropriate for autistic or people with other neurodisabilities as they involve quite a lot of thinking about the victim and how they feel etc which in an autistic person won’t help prevent meltdowns and is likely to lead to more shame and self hatred which isn’t helpful.
he’s almost certainly not ready for healthy relationships work.
