<human>: I had a friend, lets call her "Jennifer". She and "Derek" have been dating for 3 years now. In the past, Jennifer would run to my house because Derek would beat her up and would come looking for her. 

Derek is a very scary and manipulative man, last year, he broke my window and almost choked his friend with my wii cables in my house. He got away with not paying for damages because his friends lied on behalf saying that he was pushed into the window.

I feel like I've done everything I possibly can for her (I called the cops, took him into student judicial affairs, but she chose him over her friends which ultimately ended our friendship.

Now, last month she called me in tears asking if I can make a statement for her on how Derek effected me because he beat her up and called the cops on her and said that she was the one who was abusing him, resulting in her arrest (He is 6'2'', Korean, and a swimmer and she is petite so come on...). I wrote it for her and I was happy that she was able to see her mistakes...

However last night, I saw them at the bars together. I am in disbelief. I do not want to see her dead somewhere so what I'm asking is how can I help her? Or is she too far from help now?

Provide a brief overview of the text.
