He became upset and resentful. This led to a violent quarrel with his father on Christmas, and he moved in with an alcoholic prostitute for a year. In 1884 Van Gogh had a romance with a neighbor's daughter, who shared his interest in art, but their marriage was opposed by both families. This and the death of his father in March of 1885 caused depression. At that time Van Gogh made his first major work, "The Potato Eaters". In September of 1885 he was accused of making one of his sitters, a young peasant girl, pregnant and was ostracized by the local Church. He moved to Antwerp, where he studied color theory and painting at the Antwerpen School of Arts, and matriculated in January of 1886. While he was away, his mother and sister moved. They left behind almost all of his paintings, of which 70 were bought by a junk dealer and some were burned.
