READER'S MAIL: Am In Love With Him, But He's Already In Love With Someone Else!!!

For Conveniency, the writer's name is Anita, and she need suggestions from people on what she has to do.

Her mail;
I really like this guy in my class. He's funny and
charming. And I really like him. And when we were in
class he always chances back at me. I wouldn't say
he is the hottest person I've seen but I like him. That
sound really selfish but I only said that I'm
not just looking for someone hot. He's really nice but there's one problem, he's got a girlfriend. When
I found this out I was heart broken.

Do you think I still have a chance? This prolly sounds weird but I think about him all the time.
What should i do?
