Hows this for a goodbye?

Look I really liked this girl and we live right next to each other but im moving tomorrow. We were good friends but she had a boyfriend and I couldn't hold my feelings anymore so I told her but she said she didnt feel the same. She did give me strong signs though, she had said if i wasnt with my boyfriend I would say ure name....:( she said that twice, so we kind of stopped talking after that mostly because of me. I tried to stay friends with her so I tried talking again and it was going fine then I heard that she finally broke up with her boyfriend. It seemed like that she really broke up with him for good so I wanted to give her time to get over him and Prom was coming up so I was going to ask her. I finally asked her but she said that she was going alone with her other girl friend but she said if her friend got a date that she would go with me. So I asked her later on if we were going together she said no and that shes going with her friend. So I went alone to prom it was ok at least she wasnt with him. Thats what I thought, I saw him there and it appeared they got back together. I got hurt the fact that she said she would go with me but then he came. I understand the fact that she would choose her ex over me but her friend still didnt have a date. IDK i just wish she was mine. I was a little mad at her so I gave her the cold shoulder. after a while out of nowhere she avoided me. It hurt so bad, but it seemed like she thought I hated her or something so she left the room without saying anything to me. That was the last time I saw her....and now im moving. I just wish things didnt end the way they did. We graduated already and now we dont even talk anymore. I just want to say goodbye before I move. I just want to send her a message saying hey I just wanted to say hi and to tell you Im moving tomorrow. So I also wanted to say goodbye....Is there any other way I can put this in better words thanks for reading
