What should I do? I'm lost.

Hi, I'm Hope and I'm 16. I know most of the problems I have are because of growing up psychically, but it hurts anyway.

I hope it doesn't sound too overdramatic.

Two years ago I moved to a new school. Among 28 new classmates, I got along very well with one in particular. We shared our taste in music and about a half of our views. We spent every free moment together, it was great. We used to talk 24/7. He was my first real friend. He helped me with my problems. I tried to help him with his. Soon I found out he had a crush on me. But I just wanted a friend and he was very shy about his feelings, so we stayed friends. A year later I began to feel something towards him, but I would not think about it as love then. I remained silent. Half a year later I realized I had lost him (I don't know how could I not notice it earlier). He found another girl. He would not care about me at all. Anyway, month later I confessed to him and I said I still want to be friends and he was like "I'm sorry" but nothing really changed. It was may 2016. I cry and think about him every freakin' day since then and it exhausts me. We didn't say a word to each other for a few months until I messaged him because I was worried. Later he said he is sorry and still cares about me. Our relationship got better since then, we sometimes talk a bit. But I still miss him very much, although we see each other every day, as we're classmates. And every day I see him with that girl. I used to be friends with her too. I feel like she's leading him on. And despite the fact that he certainly is not happy, he still tries to win her heart over - and that makes things even worse because I see that she is more important to him than I ever was.

I don't want to lose him completely. I want to spend time with him. The problem is, I don't know how to talk with him anymore. It makes me sad, I miss the past and I can't forget about it. What do I do?

I can't stand seeing them together, I can't talk with him, I can't forget, I can't stop loving him. Is waiting for an end everything I can do?
