<human>: Sorry for the rambling, I've always been terrible at writing. 

We have been dating for about a year and a half. We met in university. It's been a fantastic relationship and I really want it to continue.

Some back story, her mother died this past winter. It was unexpected and the death was very quick. Her dad was heartbroken. He turned to religion and is very devout now. I was raised catholic (no longer practising) so I'm able to relate to him.
He's always been controlling in her life. She has to eat any food he makes for her, even if it's too much. She's come home after going out for dinner with me only having to eat another full meal. She'll fall asleep eating since it'll take hours for her to finish. If she doesn't finish he'll scream at her. 

He's extremely verbally abusive. He calls her names and swears at her. There's so much that I don't agree with that he does. She needed a new laptop, she told him about it. He gave her an ultimatum: "use my old laptop or I'll stop supporting you for school" Supporting means that he is essentially a loan. He pays for school but she has to pay him back. All of the money she earns from work goes back to him. She's always broke because of this and I have to pay for the majority of things.

There's so much to go through but I'll bring up the latest. This week, for no reason he gave so many rules. 

They were: Quit volunteering (she has some really good positions) because he doesn't see the point in it
Quit you part time job 
Come home immediately after classes
I am not allowed to come over at all any more

He said he will support her financially if she does this. If she doesn't then she has to move out. She took him up on the offer and is staying. I'm really at a loss for what I can do to help her. I haven't been very helpful, I've been angry at this whole ordeal.

Provide a brief overview of the text.
<bot>: Girlfriends dad likes to control every aspect of her life. What is the world can I do about this controlling man?
