how do i break up with a psycho g/f????

yeah myspace has been all kinds of fucked up. lol, earlier i was so sure tonight would be the end i deleted all the pictures of her and i, removed any mention of her existance, but then when i went to delete her from my friends it wouldnt let me, so i just pulled her outta my top 8. im trying to set my profile to edit mode so when she goes to summerschool tomarrow she doesnt see it and immediatly call screaming and "WTF"ing
