I am confused... :(

I come from a Mexican family, a very strict one. I am 15 almost 16 in 26 days, my parents don't allow me to have a boyfriend but when I was in the 8th grade I began to like someone who also liked me, he asked me out after being friends for a long time, but I had to say no because of my parents. I didn't want to disappoint them plus i was too young. 9th grade came and my dad lost his job, my family was thinking about going to Mexico if my dad didn't find a job, I was scared, i didn't want to leave the guy I really like because we still liked each other very much. I told him that i may be moving back to Mexico soon and that I would never be able to return. He got really upset and tears started to come out of his eyes. I could tell that he still cared about me and I did too. we decided to be together for the rest of the time we could be together. We tried to make every second count when we were together. I went great. My parents never knew what was going on, if they did they would do anything to separate us, especially since he is African American. 10th grade came, We spent 11 great months together, it was almost going to be our one year anniversary when my sister's ex boyfriend(he was like a brother to me) told me that my boyfriend had told him that he liked another girl and that he was waiting until I did the littlest thing so that he could break up with me and go with the other girl. by the way the other girl is my enemy! so i was upset, i got everything that he had ever given me, his poems, a stuffed animal he gave me, some chocolate, everything, I ripped it up, and put it in a Hello Kitty bag he gave me ( I Love Hello Kitty) and the next day at school i asked my friend New Guy( that's what I call him, My boyfriend don't like him at all) if he would sit next to me when I broke up with my boyfriend, he said yes, so In the morning when he got to the cafeteria, i told him that I knew everything and i threw him his stuff and told told him to keep his shit! He got mad, saying he didn't know what I was talking about, and he thought new guy had told me that "lie" he wanted to fight with new guy that minute. they didn't.... we had problems with the office...blah blah blah... The point is he tried everything to tell me that he is not lying, that he never said that, my sisters ex is saying that he is not lying, I don;t know what to do.... I really love him a lot still.... and I just want to end this pain. I don;t know if I should just forget about him or give us another chance. We had made so many plans together... I just don't know who I should believe.... PLEASE HELP ME SOMEONE AND THANK YOU FOR YOUR TIME... :)
