DDs friend is becoming a bully. I don't know if I'm overreacting or what to do. There's a big backstory but the basic situation is DD (undergoing autism assessment) is part of a group of 3 kids. A, female and B, male. In classes at high school DD has been split up from A. She is however in most of the same classes as B. In class A sits with C, the best friend of DDs cousin. DD and A have started sitting with C and DDs cousin at lunchtime. B tends to do his own thing at lunch from what I can gather. I drop DD at As house and they walk together and meet B about 2 mins away on the main road. B lives around the corner from us but it's a 30 min walk and DD was too scared to do it at first. I didn't push because the transition has been a bitch on her.
Since September As behaviour is getting worse and I'm worried it's going to impact on DD. School have no behavioural concerns about DD and we are in regular contact with them due to her currently undergoing assessment. I'm worried that she may be being bullied and keeping it quiet. I've seen a lot of nastiness but I think there is more she's keeping quiet about.
Since September I've seen:
A deleting pokemon from DDs game, because she didn't have them so didn't want DD to have them either. This happened on more than one occasion. DD didn't want to believe she would do it but she later admitted it.
A leaving DD at the school gates on her own and refusing to walk home with her for no reason.
A calling DD and telling her she won't walk to school with her because she wants to walk with C and won't wait for her. A then stropping when DD walks with B instead.
A sending a stream of messages to DD telling DD that she is a terrible friend so DD should hate her and call her names. Neither me nor DD figured this out but I suspect she may have wanted DD to call her names so she could get DD into trouble. She was very adamant DD call her names, she was goading her, telling her a list of shitty things she had done to DD (the things above) DD just told her she forgave her and refused to be drawn.
A hacked into Cs school log in and sent an abusive message to Cs tutor pretending to be C. This reminded me of an incident were in primary school DD got a torrent of abuse from A over a school messaging system but then claimed she was hacked. DD was upset about this but wouldn't talk to us about it. We found out via SIL as all 4 girls had been questioned at school about it and she wanted to make sure DD was ok.
This last incident broke all friendship ties between A and C for a couple of months, they have only recently rekindled.
The last 2 days A has called DD whilst we are in the car on our way to her house and said she wasn't waiting for her. DD very upset about this as she doesn't know what she did (answer seems to be nothing, it turns out that my niece has been sick so A has been walking 5 mins in the wrong direction to intercept C on her way to school) Tonight I've had a concerned call because it turns out A was bullying C on the way home tonight. I've no idea if DD saw this as I found out too late to ask her. I've been reassured though that DD WASN'T bullying anyone.
My concern is what the hell do I do? She's walking to school with B tomorrow because I asked her to before all this shit came out. We have agreed that she will walk all the way to school 1-2 days a week, slowly increasing, so it lessens my stress in the morning. If she wants to meet A she can do so at the gates where she comes out onto the main road, it's a 2 min walk from As house.
I'm concerned that A is ramping up her bullying and manipulative behaviour. I'm scared DD is being bullied and putting up with it because A just turns round and says sorry after every incident and DD quickly forgives. I'm also scared that she may be dragged into some shit A does. If she ends up being part of something where rules are broken she will absolutely fall apart. She can't cope with rule breaking. It broke her when A did it. She was withdrawn and upset for weeks and it was nothing to do with her.
Any ideas? We've tried to talk to her about if she's ok. We've spoken about types of bullying. We've spoken about how the last 2 days have made her feel. We spoke about jealousy. Nothing. She just doesn't see it.
