I need advice regarding a roommate.

My life long friend (more like a brother than a friend) moved in to my house in October. He is some what clean, friendly and easy to live with however he does not help out around the house at all and is sometimes late on rent and bills. He is unemployed and hardly ever leaves the house. He has not once helped in the yard on his own and barely sweeps or dusts. His mother is dying of cancer, he can’t find a job, does not have a girlfriend….I know my brother is down in the dumps. I’ve asked for help several times and I still hardly get anything in return. He has never given a security deposit and none of the bills are in his name. All of the furniture and everything in the house is mine. I have really nice things and I want some security in knowing that they will always be nice things which means taking care of the things on a daily basis. I am tired of living with an extra body in the house. I know he can’t afford to move out. What do I do? This is driving me crazy. Do I suck it up or do I tell him he has to move out?
