<human>: Give me a shortened version of the text

Ladies and Gentlemen,

I am in a toxic relationship and I need to figure a way out of it. To summarize quickly the girl I am with has physically abused me, put me down, has a very short temper, and makes me feel like an unequal partner.

Now don't get me wrong, I'm a 200 lb white guy and she is a 90 lb Asian girl, it's not like the punching hurt, I am not trying to come across as the victim. Lord knows I have my faults as well. 

At this point I am getting a little desperate. I have tried in three occasions to break up with her over the last two years and she has always managed to break my resolve and get back into my life. I know this is a weakness. 

What I am asking and looking for is some guidance from people who have been where I am. Trapped in a codependent, toxic relationship relationship, and how they got out of it.

P.S. The current living arrangement is she technically lives at home (doesn't pay rent) but spends 5-6 days a week living at my place (lots of her stuff is here)
