<human>: Can you give me the gist of the text in a nutshell?

Long story short, I live with my girlfriend near our college. I have plans to move back home (700 miles away) and transfer to a cheaper school. I've already given my 2 week notice at work, and plan to leave within the next month.

The only obstacle in this scenario is my girlfriend, who seems to have severe issues controlling her temper. Maybe it's BPD, maybe she's bipolar, I don't know. At any rate, any sort of argument devolves into name-calling and threats. Some of my clothes magically disappeared the last time we had a major argument, but she doesn't know that I know that. 

I want to be respectful about this and give her as much notice as possible, but I'm afraid that she might start destroying my belongings or trashing the apartment that we share (I already plan on paying the next few months of rent in full, just to help her out. She makes enough money to live comfortably without me). 

I simply cannot take it anymore, and I don't know what to do. Just short of leaving without telling her (which I think is a shitty thing to do), I don't see a way out of this without some sort of collateral damage. 

Of course, there is the added inconvenience of having to live together for a few weeks after I break it off. 

Does anyone have a solution? I already had this conversation with her a few months ago when I was just considering it and it didn't go so well.
<bot>: Breaking up with girlfriend that I share an apartment with. Don't know how to do it without her going nuclear, as she seems to do whenever she gets upset.
