What should i do? is it normal to like someone for so long?

I’ve liked this guy for almost five years now. It all started when one day when our teacher changed the seats and we were placed together. The reason that I’ve liked him for so long maybe the fact that he was the first guy that was really nice and friendly to me without judging me by my looks. By of that school year I asked him out. His answer was to wait for the following school year to start a relationship. At that time I was really overly obsessive about him that my friends started to complain about how I talked about him too much. I got his number that last day of school and talked to him a couple times throughout that summer. When the next school year started and we started talking every night on the phone and gradually we got to know each other really well. In school we acted as if we didn’t know each other, but on the phone we were good friends. My attempts of asking him out were countless and I didn’t give up until the 7th time. When two years passed by as friends, my family and I moved to Canada because of my father’s job. That summer I moved away thinking that I would never come back. When one month passed by and my parents told me that I could move back and live with my uncle if I wanted to. Because of this guy, I did. We continued talking every night and took each other as friends. I tried to hold back my feelings until one day when I saw him making out with his girlfriend in the hallway. At that time it was the fourth year we talked to each other every night. I knew that I had to face reality that he didn’t like me more than as a friend, but I couldn’t face it. I lost control and got mad at him instead. That night I exploded all my bottled feelings and confessed that I still liked him. When he found out that I was going to move back to Canada to live with my parents he started to find more time for us to hang out together on weekends and I got to know his family. Those times together rather made me think of him even more and made me believe that there was somehow hope for a long-distance relationship. It’s been a year now since we have seen each other, we talk about once a month but I still can’t stop thinking about him. Every now and then I think that he is ignoring me but then I forgive him by thinking that he is probably busy. I don’t know what to do next… forget him and our five years of friendship, or is there another solution to my problem?
