What is all the risk and danger talk about this computer? Does he keep his important files on there? Aren't they with him at his apartment?
I would not want to share a computer AT ALL with your H. Can you have a separate one? If you mess up your own computer, it should be your loss of files, your problem. I don't get all the risk and danger talk from his end. Sounds rigid, compulsive or like it could have a separate computers workaround. Is it some "you've compromised the network" b.s.? Maybe then you want off the network.
