When I was 14 I meet this boy who was older then me just two years. We hit it off right away like if we known each other.since then we just started to talk and I felt happy , I liked him from a 2 weeks and I didn't want to tell him that I like him because he had a girlfriend. He used take me out of class to just talk and give me picture then school year was over and we talk for a while and one day when is started my new school he was mad because some girl telling c**p and he got mad and he told me he liked me. And that's the end of that I told him I liked too but he was in a relationship.since them almost three years why can't I get him of my head I almost think of him and and boys have asked me out but I still think him. Why?
