Why won't she tell me its over?

I been dating a girl for about 6 months, we have been talking for almost a year. Things were really good for those 6 months until.. I found her diary which for dumb reason I picked a page to read. On the page I read I saw she feel asleep in her baby fathers bed! That night I read it we still had sex, which was the worst sex we have had in our 6 months together. For the first time in my life I met a girl I don't want to lie to.. So on the drive home I called her and told her what I read. She called me a pig for still trying to sleep with her after reading what I read, telling me it looks bad but its not what it looks like. We didn't talk for a couple of days. The day before I left for vacation I went to her house she kissed me and told she loved me. While on vacation we texted, she told me she loved me, wished me a happy Fathers Day, sent me some really skimpy photos. Being back from vacation now for a week, we haven't really talked .I did ask her out for a weekend date yesterday and with out hesitation she said yes. But for the last week and half its been 99% the cold shoulder! I told her maybe we need time away from each other, she says no. We need a break I tell her she says no, what about we just stop talking she says she doesn't want that! It feels like its over to me. The why she is acting it feels like its over. Why won't she just kill the relationship. I need your help ladies I need some female insight!
