<human>: My girlfriend has an abusive dad and is abusing her verbally and mentally. He used to physically hurt her but doesn't anymore. Practically every time he sees her he tells her that she is worthless piece of shit and has no friends and yells at her even though she has done nothing wrong. I live in a different state and unable to do anything about it. Every time she tells me what he has done to her it makes me want to call Social Services or someone to help. He was almost kicked out of the house but they couldn't because with out him they can't afford bill payments. He has also being talking shit about me calling me fat, ugly, and a loser and has also threatened to kill me if I go near her again. Although I don't care about what he thinks of me, I'm more worried about him trying something when I visit or even move to the state for college. I tell her that she needs to call someone for help but she doesn't. She has told her mom who does nothing about it because "If I do it will only get worse". There is nothing much that I can do and It's being stressing me out and depressing me.

What can I do to help stop this?

Can you give me a shortened version of the text?
