<human>: Condense the text into a few key points

Title says almost all.  We've always known that the long distance thing would never work.  We wanted to have one last hurrah for the end, and we have planned and booked a week long trip that begins on Thursday, after which I leave for college.  Last night she told me that she and her ex have been talking for about a month and they have been planning to get back together when school starts for her. 

Naturally, I freaked out about this, but she blew up at me afterwards and said I was playing the victim, and that it was my fault that she was drifting towards her ex because I didn't text her enough.  

What the fuck do I do? I love her, but part of me hates her at the same time.  I've always feared that she has been using me because she doesn't want to be alone, and I feel like this proves that theory.
<bot>: Girlfriend is already planning to get back together with her ex when we both leave for college in two weeks.
