I ' m going to be honest with you , since you are an adult . You are the one being irrational and a bit ungrateful . Unless there ' s a contract between you and this lady , she has every right to ask you to leave her home . It ' s her home , after all , and you ' re living there rent free . Since you mentioned she ' s wealthy , I can assume this is a rather nice home you ' re living in , some not closet sized room you have to pay $ 800 a month for . Also , because it ' s her home , she has every right to ask that someone stay in her home while she is away if she doesn ' t know you that well or there ' s no actual contract between you . Maybe she ' s concerned about the security of her home and assets , etc , which , as a home owner , are within her rights . The only advice I can give is maybe writing out a contract or addendum to an already existing contract , if one should exist , that concerns the food . Or perhaps purchase yourself a small fridge you can keep in your room . Otherwise , unless you ' re paying rent or there ' s an actual contract between the both of you , you ' re not a tenant , you ' re a guest , albeit an ungrateful one from what I can gather by your post .
