My friend and ex boyfriend like each other..?

I met a boy on Facebook. I'm 15 he is 17. It was really fun talking to him so I decided to meet him at a basket ball game surrounded by a lot of adults. He arrived and he was perfect. I had never been kissed before I met him. And right away I knew that I wanted to kiss him. He kissed me that first night. We talked for about a month or two before that so I felt like I knew him. He didn't go to the public highschool in fact he goes to centeniel. One of my friends(Lexi) knew him already and she told me he was cute and stuff like that I agreed. So about 8 weeks ago we broke up cause he was gonna move away then he begged his dad if they could stay and his dad said yes so we got back together. And then I had to brake up with him cause we hardly saw each other. My friend(Lexi) rides the same bus as him and they see each other almost every single day. Today they rode the same bus and it was cold he have her his sweater. She arrived at school and bragged about it. Telling me that he was never gonna date me again, and stuff like that she felt bad after ward and cried during class under my breath I called her a ***** and a skank cause she kept saying she wanted to do him and feel his penis between her hand, she wrote me a note saying she was gonna do everyone a favor and kill herself I said thanks. Later that day she told her group of friends (juggalos and juggalettes) what I said and one of the guys came up to me a punched me in the ribs for which I kicked him in the umm yeah you know. And now I have a huge bruise. And I called him and he said he wanted to date her. And that he just didn't want me to go around saying stuff about him. Which is now the reason that I have a swollen rib that hurts hella bad and is really black.
