I Am In Love With Someone

I've been in love with this guy in my school for a year and a half now. We were close friends and classmates. But by the start of this school year, we've stopped talking. I wasn't surprised actually. We had been distancing more and more during the end of last school year. Now we're in different classes and we act almost as if we don't know each other at all. It hurts a lot. I've never confessed yet I was filled with false hope. I tried keeping myself busy to ignore the sadness and pain but it didn't work. I've given up on even making friends with him now but I've never moved on. I still love him. It's his birthday soon. I'm struggling whether to send him an email wishing him happy birthday. Last birthday, when we're still close friends, because he loves Chemistry, I begged my father to give me some chemicals and gave him them as a gift. I really miss him a lot. I still don't know why we distanced for sure but deep down I know it must be because of me. Maybe I was too clingy. Or too annoying. I don't know. I miss him. I love him.
