 The relationship between Maria Theresa and Joseph was not without warmth but was complicated and their personalities clashed . Despite his intellect , Maria Theresa 's force of personality often made Joseph cower . Sometimes , she openly admired his talents and achievements , but criticised him behind his back . She wrote : " We never see each other except at dinner ... His temper gets worse every day ... Please burn this letter ... I just try to avoid public scandal . " In another letter , also addressed to Joseph 's companion , she complained : " He avoids me ... I am the only person in his way and so I am an obstruction and a burden ... Abdication alone can remedy matters . "
