<human>: Give me the gist of the text in a nutshell

First off, his father is dying. He's on steroids which make him very mean but apparently he has been mean my boyfriend's entire life. What he does is that he makes his kids feel like they have to stay in their room all day. If the kids aren't doing something that the father wants them to do, then they're not allowed to do anything. They can't stand up to their father or he would throw them out of the house. My boyfriend simply can't do that right now. He'd have no where to go. Now, the father pushed him over the edge tonight. He broke down sobbing because he couldn't handle it. It was something neither of us saw coming. I sat in a parking lot in my car down the street from where he lives while on the phone with him. I was trying to find out if I should come up and pick him up. In his house, no one can just walk out. Not even my boyfriend's mother. That's something that is just not done. So my sobbing boyfriend went downstairs to *ask* if he can go with me and his father starts yelling at him. No, he couldn't come. Now my boyfriend is very unnerved because he says his dad knows his weakness now. He knows how much my boyfriend cares about me and will use me against him. "He'll make my life smaller," he said. I encouraged him to regard that as bullshit but he insists that I don't understand. And that he'll be thrown out of the house if things aren't done his way. 

Can anyone help us at all?
<bot>: Boyfriend's controlling father won't allow him to do anything besides what he tells him to do. And right now, he's forbidding his son to see me.
