Is it a fairy tale? Does it have to be?

Okay so me and my best friend. Okay so when I first met her she was dating my best friend. We were like opposites. She being a goody-two shoes. Me being a bad kid. Like She hates swearing and I used to swear a lot. We didn't fight but like at one point she wanted to sit somewhere else and avoid me altogether.My friend hurt her. So they broke up. I wanted to talk to her because I did like her and wanted to help with the pain. I wasn't trying to play off of her pain either. I was worried about her. I tried on so many situations. I'd almost talk to her but it felt like she was giving me dirty looks. So we had no contact for like 3 months. Well I started talking to her on facebook because my friend started being a jerk to her again so I was wanting to help with that. She wasn't upset or anything just a little mad. So when we talk again on facebook I find out that she cuts herself. (Please don't judge). And So do I. Mine getting more aggressive. So we share that and talk about it. By this time she's dating some jerk. We keep talking just as friends. and we have epic talks on facebook. like for our third conversation on facebook it was over 4 consecutive hours and we stopped because we were tired and had school. I'm not trying to break them up. If she's happy then I am. So we're friends. but see she's not happy with this guy. While talking on facebook we become best friends. So her boyfriend is being a real jerk one day. and on facebook she says that she wished she had a boyfriend that cared as much as me. Then I say we'll maybe I've thought about being more than friends. she says the same thing. so we want to be together but she wants to let the guy down because they were friends and she wants to still be friends. So when they do break up, Me and her start something but we kind of take it too fast. I'm all sloppy and bad at this because its my first time kissing someone. I'm a nerd who has had crushes but never pursued anything because I've thought things through and realized it wouldn't last. We made a promise to stop cutting. So I end up hurting her and losing her trust. by cutting myself. she tells me that I'm not the same that I'm always sad and that I've changed. So I decide to go back to the way things used to be. To start over Being happy. That we won't kiss but we'll work up to it. But the next time we see each other we end up kissing. So I hurt her again and break her trust. by saying that she's becoming cold. Because she became emotionally numb after I hurt her the first time. This breaks her numbness. So things are good but then I hurt her and lose her trust completely. I let something slip while going off on someone. So she said that we won't be anything more than friends and that she'll never trust me again. But when we get together we do end up kissing and being more than friends. Now we're together. We do love each other. We talk on the phone usually from 4-6 hours at a time but sometimes we'll talk for over 8. our record is over 10 =) We talk all day, everyday. Like from as soon as we get up until we fall asleep. She pretty much saved me because I would've probably killed myself if it wasn't for our promise. We don't really fight or bicker. She might get mad every once in while but nothing extreme or severe. I'm never mad at her. Is this a fairy tale love story? She doesn't think it is. Like she wishes that I would've told her in person that I liked her.(Which I wish I would have). I know I've hurt her but I really do love her. It was an accident.
