Does it matter? You know race?

I like this girl that sits next to me in cl. She's quiet most of the time but I blow kisses at her and today kissed her hand. I tell her all the time I think she's pretty and she'll smile at me and say "Awww thank you Jay". I'm afaid to talk to her like that though because I'm black and well she's not. She's really cool but I'm not sure if she likes me like that, I believe if she would it'd be kinda obvious right?
