to send a Facebook friend request to a girl who bullied me?

[NaiveMoi]

Long story short(er), was best friends with girl in high school for a few years, then she decided I wasn't cool enough to be her friend. Dropped me like a hot potato but not before making me feel like shit. I've always been shy but the way she behaved knocked my confidence even more, and I still find it hard to make friends to this day.
We have mutual friends on FB, and I've been tempted to send her a friend request on several occasions. If I'm honest, I'm hoping she might have realised what a bitch she was and apologise. I realise that's probably hopelessly optimistic; she'll possibly just ignore the request altogether.
AIBU? Should I forget the whole thing? I feel lke if I don't do it I'll always wonder..

Things change. I have reconnected with childhood acquaintances and it's a different dynamic now.

I've also found that 'bullies' often don't realise they are bullies or have forgotten their behaviour.

I had one girl say I bullied her at school when I always thought she'd bullied me!

Obviously part of this is relative to age.. if you were bullied in the sixth form and you're now 20, things may not have changed but if there's a bigger gap, you may find things very different.

If she seems like a normal adult woman now, it's worth opening communication and gently saying, "Hey, I found you quite intimidating at school..." or whatever, which opens the gates to a conversation but I wouldn't expect an unprompted apology out of the blue.
