can you get her back?

i got dumped 3 times in 2 days by the same girl and she gave me a second chance to show her that i realy did like her.. she broke up with me because she siad i didnt act like i liked her, but she was always up walking around flirting with other guys and not realy paying attention to me... i realy liked her but if she wants me to act like i like her shes gonna have to act like she likes me to.
