<human>: Can you summarize the given text in a few sentences?

I can go into detail if need be, but in short, I've known this girl for about 5 years and in that time have "dated" on and off for a total of about 12 months. In mid 2013 I completely cut contact with her because I was sick of the abuse and control and dated another girl for a year and a half. We broke up, my dog died, my mum became sick with terminal cancer and I have people who are after me and trying to kill me. Out of desperation, I went crawling back to said (26/f) and nothing has changed. She controls my finances, hurts me and puts me down. I still love her though, and she does sometimes make me feel better about my life.
<bot>: my life has gone to shit and I'm back together with an abusive ex who hurts and scares me, and I don't know what to do because I am in love with her anyway.
