FIRST of all, thank you for reading all of this. I really appreciate it! 
Just so you know, we are both Freshman in high school. I know, nothing should be serious at my age. I understand that. I just miss her, I don’t want to be alone, she is a great person. She is the best person for me right now. I don’t want to be single, because all the other girls that are pretty at my school are sluts or are really stupid, and I don’t want to date anyone at any other schools. I just want her. She showed me how much fun it is to have a couple.
I used to be a big flirt like her, and i refused to date anyone. Now that she finally got me to ask her out, after much hard work on her part, I love to have a girlfriend (or her as it). She used to be obsessed with me, and now it is all gone. If she felt like that before, can’t she feel like that again?
Anyway, My ex-girlfriend and I have been broken up for four months now. She broke up with me because we went through some rough patches, I lost interest, said that I was about to break-up with her, then went on vacation and missed her and changed my mind, but then she turned around and dumped me. I never wanted to hang out, talk on the phone, or text. I was a really bad boyfriend at the time. But I learned from my mistakes. And she knows that now. I have proved it to her.
The only thing is, another guy came in the picture. She went to winter formal with him (I went to homecoming with her, and that was the night I asked her out). Now he is attached to her. He is a lost puppy that follows her around anytime she goes to her locker. He has lost his life, it revolves around her. Of course, she liked it at first, because it was the attention that I never gave her. But now it’s both me and him giving her the attention.
Also, they are not together, and never have been. She tells him that she does not want a relationship right now and wants to be single (she also says that to me). She likes being able to flirt with any guy that shows her attention. She doesn’t want to restrict herself to only one guy. Anyway, he tries to call her a lot, too, and they talk on the phone. That really bothers me.
I’ve changed so much, in a good way. I mean, I changed all my BAD habits like not calling or texting, and ignoring..and not appreciating..and not noticing. She finally believes me that I am going to be better this time. I did every trick in the book to try and get her back, hah. I asked 50 questions on here, read 5 e-books, and did research on the web on how to get my ex back, and how to attract women. Haha, yeah I’m pathetic, but it will come to use again later in my life when I’m in the real world.
So yeah, she’s decided she wants to try and make things better between us now. She want to try and get us to work again. But HE is in the way. She is a nice person, and she doesn’t want to crush him and break his heart, because he is literally obsessed with her. She has try letting him off slowly and easily, but he just lets it blow by him. And he keeps on following her and talking to her like nothing is happening. It’s so frustrating for the both of us. She still likes him a little, though..
Although, I think she is lying to me. Maybe she just doesn’t want to hurt MY feelings. Maybe she just doesn’t like me anymore, even though she flirts with me and dirty texts me.
She and him are not going out. Her and I are not going out. Everyone is single. She says she wants to stay single and have fun, without being tied down.
Anyway, what could she do? What could I do?
How can I get "us" to work again?
I KNOW that it would be a way better relationship this time if she just gave it a chance.
Also, could there be a possibility that she actually just doesn’t like me anymore, and is just playing me because it makes her feel good?
She made a deal with her best "guy" friend the other day. It was that she had to choose the other guy, me, or her single life. That day she told him that she likes the other guy and that she is over me.
The stupid thing is, she is still calling me "babe", she is still calling me up randomly to say that she misses me, and she is still getting angry with the little things I do. I don’t believe she is over me, but she might be.
>>>>>How do I get her back? …If not that, How do I move on from her?
Thank you for reading all of this 
I feel that I need to give detail in order to receive good advice.
BTW, I actually prefer long answers (unlike other people on here) if you don’t mind. Don’t be afraid to say everything on your mind.
