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

8 months ago i asked out my now ex gf the first month was rocky, second and third was a breeze. I was gone for months 4 through 5 because of basic. When I got back relationship was at its best. We started to argue and fight more during our 7th she became very physical and I became a douche in response and overall acting cold towards her. I called it off and tried to move on (got hurt at basic and came home, restarting my process currently, and I was holding her back from improving her life, and she was in the way of my progress to re-up)I stated the issues (along with our mutual hostility towards each other, and told her it's over.

The problem though she wants us to get back together when both parties are ready, and I agreed. However, she still acts like we are together and I do to, but I'm not as open with it as she is. I've lost almost all feelings for her and don't know how to tell her I have no intentions of coming back. Advice?
<bot>: Broke up with girlfriend she was abusive and I was an asshole. She still wants us to be together we kinda act like we are but I don't want to. What do?
