So i do i get this girl to not hate me again?

Personally I'd say just leave it. Just because she is attractive in your eyes doesn't mean you have to keep trying to ask her out. In my opinion, her answer has been pretty clear the whole time. Some girls just like to flirt for the attention, not because they want you to go out with them. I've known a few like that. Cut your losses, move on, let her go. Tell her straight how you felt, but don't do it to try and win her over again, just to explain when you were acting as you did. Then try your best to move on
