I don't knwo

I love someone and his name is star (in my country spelled different)
I always calls him my star and trying to get his attention.
He doesn't have girlfriend
But he's so cold to me, seriously.
Other people don't like me because of that and I know they talking about me behind my back.

But today, I saw him with some girl and he is so nice with her.
I thought "ah maybe he can be nice to me too"

But I'm wrong, when I try talking to him, his give me a cold tone answer.

I never bothering him
I never stalking him
I never do something rude or worse

I just call him star ( star in English). Thats it.

Should I give up and move on?
But, it's so hard to forget about my feeling.

I realized today that I need to stay away from him

I want to cry so hard now.
