<human>: Can you succinctly summarize the text in 1-3 sentences?

Our bed, tv, and computers all stay in the same room because he is uncomfortable branching out into the house. His grandfather basically always treated bf as community property for him and his sister (also abusive) who lived with them. Or as a prop/servant if there were guests. 

His bedroom was the closest he ever had to his own space. Even though he'd often come home to find it torn apart (dresser drawers torn out and upended, closet completely dumped out, mattress flipped and sheets inverted and left on the floor etc. He was then screamed at to go clean his room.). At least when he was home, it was his sanctuary. 

So now he's having trouble spreading our life outside of one room. Especially he's uncomfortable with moving the computers. 

Therapy isn't an option for now for multiple reasons. How can I personally help him get there? I'd really like to have a separate bedroom and use our living room.
<bot>: Bf was raised in an abusive household and now doesn't feel comfortable living in more than one room. Therapy is off the table. How can I get him there?
