Is it wrong to wish that she gets as crushed as I was? I feel so conflicted like I want to hate her and let her know how I really feel, but at the same time shes such a good friend that I can't....isnt highschool drama fun?

yes, it is. as much as this is not answer you might want to hear, it is; means you are still stewing in your own bitter juices of not forgiving her and poisoning your own food with those juices. unless you can say 100% honestly, to yourself and anyone else, that there is no resentment left, in which case it still is wrong to keep thinking about it because you'd still be stewing in your own bitter juices of not forgiving yourself for your past mistakes and poisoning your own food with those juices. so if you still have a problem with her dumping you, or think you do, which it sound like you do but i can't say for you, then go and tell her that, explaining how it made you feel and how you still want to her crush and burn or whatever it is that is left unsaid. but don't hope that she does burn. wishing she burns is nothing but self-pitying revenge i think, so instead just let her know how you are left feeling after the brake up. if you can't face to face, do it in the FB message, i guess. but be nice about it. friends can talk about past hurts, pains, problems, etc(including past brake up baggage) and still stay friends. and if she dumps you after you try to fix this completely, then you have to wonder if she was a friend or just wanted you around for whatever reason and un-friended you when things got to complete honesty.
consider your motives, too. if you still want to get back with her, then that could be why you think you are out for revenge. so do some honest admitting if there is some, and accept that its over. this would be especially important because if you start talking about it, she might start wondering and then eventually ask if that is what you are after still, to try and get back with her. so by then you can say with clean conscience that no, it ain't.
when you do talk to her, go with something as civil as possible, like, i don't know, maybe like this: "i think i am still not over you dumping me. [or "I am still not completely over the..."]. its not so much about wanting to get back together or the dumping itself as much as that you don't know how painful it was and i never got over that because it was never fully discussed..."
(adjust text to fit prompts of your own conscience, i'd say. plus, if it was fully discussed, full closure, then you, my friend, just need to move on, including forgiving yourself for your fast mistakes)
or something like that. don't just fire up "you [censored], why you dumped me? don't you know it made me feeling like [censored]?"
if you insist you need to fire up like that but don't want to upset anyone, then do it in like Word document, as if you are writing to her, and just unload it all, no matter how hard(freedom is in letting go, even if letting go is hard or you don't feel like letting go) and then delete it all, don't save it, just type, unload, delete, and forget. if something is left over after this experiment, consider that this is how you still feel, so might want to either get over whatever remains or hope she won't send her bf after you and or un-friend you, etc for your honest disclosure or for your trying to get back with her or whatever.
and as Mamagato said, generally, if you have to wonder, you pretty much know it is.
