Why is she soo confused?

I think she just wants you to chase her. She probably loves the attention you give her, therefore she feels if she acts like she doesn't want you, then you'll continue to pursue her. I'm going to tell you like this, don't play this game with her. Act like she doesn't even exist, and you'll see how she'll react. She doesn't deserve your time or your energy if she's just going to continue to play a game with you. Move on. Although you might have feelings for her still, those will fade away with time, believe me. Just try to ignore them and just move on with your life. She'll come around. And if she doesn't trust me there will be plenty of females you will meet in your life.
