<human>: My girlfiend, whom I've been dating since last november has had...a fairly angry father, he had hit her in the past, over a guy she was interested in and I've been trying to be supportive, and loving.  Things have been rocky at times, when her father just pops in and screams at her (she lives in a house he owns).

An incident happened recently involving her older brother being beaten, and shes now thinking of ending it with me because shes afraid of what will happen if her father finds out we're dating.  He doesnt know because shes been afraid to talk to him about it due to an incident in her past.  She lives 3 states away at this point and I'm just so scared.  I dont know what to do.  Has anyone been in or dealt with someone in a similar scenario?  Shes absolutely terrified of him and has told me she really doesnt want to lose me, I'm her only reason for living (paraphrasing stuff shes told me)

I'm at a complete loss and just, please, does anyone know what I can do?

Can you provide a brief overview of the text?
