If Jack hadn't died in Titanic, would he and Rose have lived happily ever after? This was a controversial question because the movie did not give a clear answer. From the plot of the movie, Jack and Rose had fallen in love before the Titanic sank and had a good time on the ship. However, when the ship sank, they separated Jack and ran to the lifeboat while Rose froze to death. If Jack hadn't died, whether he and Rose would have lived happily would have depended on how they got along. The movie doesn't show what happens after that, so we can't tell if they'll stay together. In any case, from the plot of the movie, Jack and Rose's feelings were deep. They also had a side to support each other in the face of tragedy. Therefore, whether they could live happily depended on their relationship and future development.
