Does my ex best friend deserve this? I know it's long but i'm desperate!?

Okay basically I had a best friend and we got along so well, we told eachother everything you know all that usual best friend stuff, but towards the end we argued alot about the most random and pointless things so yeah things weren't going great but yeah anyway so she knew about this boy that I had liked for years and he was soo difficult to be around cause he was unpredictable so she knew how happy I was when he started to talking to me again (we were really close for agees then a pointless argument happened which wasnt even my fault and we ended up not speaking for a year) so then I ring her up one night and she tells me she's with someone and told me to guess then she admitted it was the boy that I liked, now he hates me cause she made it out like I was obsessed with him so yeah that happened so I dropped her as a best friend and she replaced me just like that! But then 4 days later she got dumped by this boy and about a month later her new best friend dropped her! I had forgiven her by this point but then I find out that she's the person who hacked my hotmail account, changed my pword, hacked my Facebook, changed my Facebook pword, read my inboxes, sent the ones of me bitching about her to herself so that I knew she'd seen them and made it look like it was just someone trying to ruin my life and she lied to my face for 2 months about it, let me be friends with her and only admitted it when I mentioned that I was gonna get the police involved to find out who it was, so just to get at her a bit, on her birthday, I've made a reservation at the same restaurant and the same time as hers, and I'm gonna turn up with 2 people that were meant to be going there with her, I know it's childish but I kinda think she deserves it! Opinions and comment please?! Btw I'm 14!
