Back to the apartment situation: Could you put in writing to the landlord father that you are not imposing, but the agreement was that you would do the cooking and some of the housekeeping in exchange for rent. That you do not drink, smoke or party (assuming these are true)and that the roommates appreciated your presence and it was for a defined period of time, say one year. Then get daughter and roommates to back you up. Seems like father landlord would want a good influence on his daughter.
