How many times can you hit on a dude and he don't even care?

My crush Ridge I've tried flirting with him but he doesn't even realize that I'm trying my hardest to make thing's right with us but he throws it back in my face. How can I win him over without him throwing my words back in my face. I've tried over and over and over to make him be my friend or at least for him to realize that I'm not what he thinks I am but he still says that I'm what he thinks about me. I really want him back tell me how do to win him over.
