Ruth initially encourages an engagement between Rose and a wealthy suitor named Cal Hockley primarily because she believes it's an advantageous match considering their declining socioeconomic status after her husband's death. However, it becomes evident as the movie progresses that she cares about her daughter's happiness and isn't willing to force her into a loveless marriage for mere societal benefits. She ultimately supports Rose's decision to choose love over societal expectations with Jack Dawson despite Jack's lower socio-economic standing.
