Brother might be moving in TRIGGERS

I KNOW what people say about letting family move in, but he really has no options. He had to drop out of college (he is 19) because he couldn't afford to go. He can't get the pell grant because he would need my parents info for it and they are just impossible. They hold everything over his head, I would know, they did the same to me. Basically, his car needs repairs that cost 3 times as much as it's worth, so he's going to have to junk it. His roommates and their friends are stealing money from him and he is already broke. The people that his roommate brings around the house not only steal from him but are dangerous: they carry knives and guns and sell drugs. His friends live with their parents so it's not an option to live with them. My parents, IF they even let him move in, would hold it over his head forever. My dad literally wants to see him fail and he told him that. (He's said similar things to me). My brother is gay and my dad shames him for it ALL the time. So IF he even moved in with them, he would be subjected to my dads emotional, verbal, and probably physical (he choked him before) abuse on a daily basis and just have to take it because that's the financial situation he's in.

He is currently trying to get a second job to change his situation but hasn't been successful yet. He has been really down about everything lately.


DH and I want to let him stay for a few months to save up money, go back to college, and get on his feet. I am sincerely worried for him right now. BUT there are boundaries that we will set, there has to be. I need advice on what kinds of boundaries to set and advice on this whole thing. He literally has no one and has been working his ass off to support himself.
