<human>: Give me the gist of the text in a nutshell

About 2 weeks ago my girlfriend who I lived with for a year and a half and then went LDR with for the past few months wanted to take a "break". She says she's not sure she wants to do the LDR thing for the time we will be in grad school because she says she doesn't think we'd have time for one another and it wouldn't work out. I agree to an extent that it would be very difficult to be 13 hours away and both doing grad/law school.

However, her reasoning recently became that she just wants to be "free" and not have to work at anything right now. She's been going to parties and things and doing drugs and stuff now that I'm not in the picture technically and I'm not against this, however, it seems to me to be more of a break up than just a "break". We had talked of our future and it seemed our futures coincided with one another, but then out of nowhere she said she thought our interests were just different now.

My problem is I tried cutting her out completely and I couldn't do it. Not because I still think things could work or anything, but because I don't want to lose what could become a friendship over this. Also, she has a habit of changing her mind and getting bored easily so I feel like in the future she may come back to me looking for security and that normality we had and I don't want that. I'm confused as to what she's getting at and I want to move on.
<bot>: 2 year relationship that I know wouldn't have worked in the long run. Getting mixed signals and can't cut her out completely. What can I do?
