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

(This is my throwaway account)

We've been together for a long time, with me as the sole provider while she stays at home.  She used to have friends, but they moved out of the area, and her family is no longer alive, so handing her off to somebody else isn't an option.  

Over time she has become vindictive and bitter, has cheated on me a few times, and has done many other things that are textbook manipulation and emotional abuse.  For the past year (at least) we've been doing nothing but bickering and being miserable.  The time for reconciliation has passed long ago.

The only light I can see as a way out is that she plans on attending college (and that can be a way for her to move out into a safety-net structured system).

Any and all advice for how to get her to move on with her life without relying on me would be greatly appreciated.
<bot>: It's time for me to move on, but I can't just throw her out on the street to be homeless.  I can no longer stand her, but I'm not heartless.   What to do?
