How can I get rid of my player reputation?

this girl was very interested in me, then after we made out for the first time, she told me she didn't want a relationship, then pretty much lost all interest. I know she lost interest because she replies with short answers when I text her, and almost never initiates a conversation. So once again, what happened? Is there any hope of sparking her interest again? I'm pretty hurt about her sudden turn off to be honest
