Strange Day

I was happy the whole morning. I just woke up, and I saw my English scores. I know it's not so polite, but I have to say that they are so good. The highest score was 25, and I got 22 23 21 and 24. Then I went to school and I saw my scores, so good too.
But... my life is not complete. It's not all about success, I need to be happy in other way, love way. I know it's stupid, and that I'm so young to think a lot about love, but I need to be ok with that boy. I want him back, because I can't understand what happened. All was ok, and suddenly, all was wrong. A few days ago I discovered he talks to other girl, and the worse parts are that I can't say him: "why are you talking with this girl?", because he wasn't my boyfriend, and that he said we were going to be FRIENDS FOREVER.
The only thing I wish is he's not dating her. He said he wouldn't like to date a girl who he only knows from the internet so...
Please, God, Help me
