I was quite badly bullied between the ages of about 7 and 11. It was on and off during that time, but I'd say between two and three of those years it was going on. The girl who was the leader of the people who bullied me has always been one of those sweetness and light people, no one who knows her now would ever think she had been like that, and tbh I don't think even she remembers how horrible she was to me. She has apologised to someone she bullied at secondary school, but has never apologised to me for what happened at primary school. She almost always treated me like something she'd stepped in at secondary school, but I don't think I'd class it as specific or sustained bullying, like at primary.
Anyway, now someone we both know wants to get us together. Not us specifically, but a group of people known to all of us. These are mainly school friends, but also university (etc) friends. The get together is about a six hour drive away from me and will be in a few months. I have been asked by the person organising it to give a lift to the person who bullied me. We are the only two coming from this way. I would normally get the train, but I am probably only going for one night as I think I'll only be able to get childcare for the one night.
I don't want to spend six hours in a car with this person. We have been civil to each other when we have been in the same group in recent years, but I am resentful at her for the way she treated me and the apology I never got, and I don't think I can spend that much time with her and not say anything.
I realise I'm probably being immature and I should get over this, but AIBU to refuse a lift to this person? FWIW, the train from her local to where we need to be is only one change and she can get a return ticket for probably £40.
