Why do people abuse others? Why does no one cares for someone who lives in domestic violence?

I live in domestic violence and trying to get out, and trying to get the help needed to get out. My family, my husband's family and our supposable advocate seem to allow this to go on. I have talked with my family, supposedly my happiness is not important, but his is.

one of my family told me to watch a movie called fire proof. How is a movie going to help? He is not going to change and or care. I am not allowed out of this trailer, not allowed to see my family, or even talk to them online or even on the phone. Just don't make any sense
