Wth..she still keep checking on me?

after learning that my exgf (she dumped me btw) kept checking my site and blog account last august, she emailed me and she mentioned that she kept checking my blog out of curiousity and saying cheesy stuff. but i told her that she should never emailed in the first place coz it will help me forget her (then we start emailing each other..its an email fight actually) but after that i told her that we should settle it and never email me again until shes open for communication again with me and give it a trial as friends...she didnt email me back coz she thinks im having my revenge. but after 3 weeks she starts checking my friendster and blogger site again..wth..is she nuts? whats with her?
