I'm in the eight grade and I REALLY like this girl named Ariel. I feel like I'm in love with her, but I dont?

really know her. But I know that she is VERYYY beautiful in several ways. Everytime I talk to her, I always say something stupid because I'm nervous. I really like her and I think she likes me too, I even wrote a poem 4 her, eventhough I'm 2 shy 2 give tit 2 her. What do you think I should do? What do you think I should say to her? PLEASE SOME1 HELP
