He told you that you only share the place with one other person, but he also comes whenever he wants, sleeps in the living room, visits your room while your not there, decides to change the rules on random occasions. He check what you do, doesnt allow friends to come in. He asks you to keep clean, but doesnt obey the same rules. He was demanding and often absent.
