First time, scared to love him, am I being selfish?

Okay so I'm sorry if this seems a little long but I think I should explain little details so you guys can help me. So last summer I met with a guy. He fell in love with me as soon as he saw me. We went to the movies once but he seemed so awkward. From his friends, I knew that he liked me. I've always had a little crush on him since we met but I didn't tell anyone. Then we had this fight and I really didn't know what to do. He lives on the other side of town so we hardly see each other. The last time we met, he confessed to me but I told I wasn't sure if I liked him. Everyday I think about him, I just can't stop thinking of him. I am in love with him now but I can not pull up the courage to tell him. I really want to tell him that I love him but every one that I care about ends up leaving me. He is leaving at the end of the year. I want to tell him but I don't think I could cope with him leaving me if we were in a relationship. Should I tell him? Or just leave it? Is it selfish of me to only care about how this would affect me and not him? I'm completely lost as he is my first love. Please help me out

Hi there. If I were you, I would tell him. Life is too short to just let potential happiness walk away. You never know what will happen until you try. I would not feel bad if he does not feel the same way because everything happens for a reason.

Hey there. Thanks for your advice. After serious consideration I decided that I should tell him the next time we meet. I already know that he likes me a lot and I feel that if I don't do something about it, it'll be a missed opportunity.
