While I think you shouldn't rush into another relationship, this one line speaks volumes in how she thinks about you. If that is her mind-set, you don't want to care what other thoughts she has. She doesn't care about your's unless they are for her.
She doesn't want a relationship with you. She wants someone to play games with. If you got back together with her, I would give it less than a week before she broke up with you again and started the cycle all over. Blaming you the entire time and getting her friend to make sure you didn't go anywhere until she was ready to take you back again.
The MySpace is just another way to play games with you.
Defriend her and her friends who are only part of the team. Delete your links to MySpace so that it makes it harder to check your MySpace page. For that matter get rid of that page and start a new one that has absolutely no memories of her attached to it.
