I've lived with my boyfriend in Oregon, for over one year now. We agreed I'd be responsible for buying groceries and some household items, and for house cleaning. He would continue to pay the bills and his mortgage (it is his home). We no longer get along, and I'm looking for a place to move. When he gets drunk (multiple times a week), he threatens to throw all of my personal belongings outside. He tells me my name is not on his house and I have no right to even give him notice that I'm going to move. Whenever he drinks, he wants me out "that night." I want to move as soon as possible (obviously) and am looking hard, I just would like to know if I have any rights for example: giving one months notice. Thank you for any advice.

Sorry, no you don't. Without a signed contract, lease agreement there is only a verbal and even in that you are boyfriend/girlfriend not landlord/tenant.
