Unfortunately this is reality. If the girl doesn't like you, then you just have to move on. Hardwork and dedication will not work if you are just not her type. It's like saying if this chick who you absolutely do not want to date suddenly keeps sticking to you, will you all of a sudden just start liking her? I'd say just leave her alone, if she realizes that she wants you then she'll hit you up by herself. Stop trying so hard and let life go on. You'll find someone eventually. [Speaking from experience, this dude been sticking to my friend for 4 years, he's still trying but it's obvious he's got no chance.]
