<human>: Can you provide a brief rundown of the text in within 3 sentences?

I will try to keep this as concise as possible. I have a history with this girl. We used to hookup and she used to have strong feelings for me. Time has passed and the tables have turned. I developed strong feelings for her, but never told her in time. She moved on and now is dating someone else.  
  
I confessed it all to her and told her that if it won't be reciprocated then I will need some distance to get over her. However she still tries to contact me and talk to me, even though it seems like she isn't interested in dating me. She said she is confused and doesn't want to lose me, but it hurts me to be around her knowing I can't have her. When she is unresponsive, my mind usually goes to the worst places. It's to the point where I am always thinking about her.
  
Should I be fighting for her or should I just be distancing myself even though she doesn't want me to? She told me I am a huge influence in her life and she doesn't know what she would do without me. The whole situation is very confusing. It sounds like she wants me, but doesn't at the same time.
