I had a text from my family member last night asking if I could ring him, which I did, he said he had been thinking about what I'd said last weekend, and feels awful that he upset me and his friend, he spoke to her yesterday and has apologised to her for his part in the name calling, saying that he didn't think about the impact his words were having, he said he mentioned what I had said about consent and she had told him that the only person who has been nice to her is the boy in question, he's the only one who hasn't joined in the name calling and the only one who has asked her if she is ok, she told her best friend the next morning and wanted help with getting emergency contraceptive, her friend then went and told everyone in their friendship group.
The girl thanked my family member for saying sorry but the friendship is over, she said she couldn't ever trust any of them again, she has told him she wants to get on with her exams and be left alone, he's asked me what he can do to change her mind and I've told him he can't, that he must respect her decision and not bug her to speak to him. That it's good he apologised to her, but he can't expect her to just carry on like before, that he and his friends were twats, and they might be able to forget it and carry on as normal, she can't.
He said the name calling has died down, but that could be just because he's not involved in the group convos anymore as he has distanced himself from them a bit. It sounds like the groups has split further, with her best friend still namecalling with one or two verbally at least, but with a couple of the others stepping away after my "outburst" the only one the girl still speaks to is the boy, but she said that that isn't the same anymore either as it's awkward.
I phoned the school, (before I'd spoke to my family member) but haven't told anyone in real life that I have done so, I spoke to the head of his year, I said I'd seen some nasty bullying of one of their pupils by other pupils over social media, that I wasn't a parent of any pupils and didn't feel comfortable giving names in case it caused the victim more stress but that I wanted to let them know what was going on, which I know isn't much use, they thanked me for my call and making them aware, if I wanted to contact again with any concerns to do so. I know it was probably a waste of time, I wasn't bothered about getting the bullies in trouble, I was worried that the girl might not want teachers to know, and naming the bullies might make them name her?
I've told him I love him very much and it made me sad to see him acting in such a way, not sad for me, but sad for the girl who thought she has friends and got shit on by them all when she needed them, I think he is genuinely sorry, but if that's came about due to genuine guilt or fear of getting into trouble I don't know. Maybe a bit of both.
