Im in love with the most beautiful girl on this planet and dont know how to handel it.?

Her name is Skyler she's16 and im 17 I literally am in love with,her I know it takes alot to love someone, but I know I do.I cant stop thinking about her, her and I are really close. it feels like were getting to close, I know she loves me but, not like that "well really IKD" but I dont think she knows how much i love her, I'd put someone in the E.R. if they hurt her, we are moving to California when were around 18, 19 years old basically after every thing to do with school is done with. and i want to be with her, I really cant explain how I feel, I dont know how to. I dont know how to tell her. and it would kill me if I heard her say no. ):
