He considers the woman to have certain obligations; these views he acquired from his mother or other women with whom he used to live. So it is quite normal for him to have some expectations of what exactly is your role. Calmly explain that you are a different person with different habits and priorities, and scrubbing the floor from morning to night is the last thing that he can expect from you. As we said, give yourself time to get used to each other and to learn to live together.
