How do I fix things? (Long description)?

[Agirl]

Okay, so there was this boy I'd liked for seven years but he never like me back and left the school. Let's call him J. I was extremely sad and then this boy came along that wasn't the best looking kid or the most popular or anything like that but he would talk to me. Let's just call him R. There was this dance at my school and I wanted to invite J but I wasn't sure if he'd want to go with me so I asked R if he thought that J would. R said he'd love to and that boosted my confidence so I called J up and asked. J said he'd go and then we danced with each other at the dance. I realized that I didn't like J that much and my feelings were changing to R. I told R that I liked him and his feeling were mutual but we decided to keep it quiet. So, we talked through facebook about our families and secrets and stuff like that. We really liked each other and it was one thing to look forward to after those seven years of rejection. All of a sudden one day he told me about this girl (let's call her L) and I was heart broken He told me that I was the only girl he liked and I though we were going out! Well, I told him how I felt through facebook and he blocked me. I made another account and told him I was sorry and that he had the right to like other girls, that I wasn't the only one. Then, he re-added me and things were a little cold between us. He quit getting on and ignored the messages I sent him. They were friendly messages asking him how his trip to Hawaii was but he ignored them. Well, the next year he lost a bit of weight and looked really great! Then, there was another school dance and he didn't dance with me! A girl saw me all lonely and all and asked him if he would go dance with me but I overheard him and he said no. Instead, he went and danced with the girl he'd already danced with two times! I was so sad and sent him another message asking him if he'd still be my friend, that things could go back to the way they were before he mentioned L. He de-friended me. I don't what his problem is! Can somebody tell me how to fix things so that we can at least be friends again? I'm not the most popular girl, either. I'm short and most people think I'm really shy. I need help! I don't want to be a dork! I don't want him to hate me, either! Can somebody please help me?
