California. I would like to know if I can get a restraining order for a roommate's significant other who will not stop spending the night over. The roommate doesn't mind him, but I do. The lease stipulates that guests can stay 15 days, which he has repeaditly gone over. However, I also have a significant other living here. Therefore, going to the landlord to get rid of him will result in the roommate telling him about my friend. The real question here is: does the roommate's friend have to threaten/harm me before I can get a restraining order?
