predict the lutant promises ms barley i'll always come back do you think he will? why or why not?

The promise that he makes to Catherine Barkley is made with the intention that he will fulfill it. He plans to always return because he truly loves her. He, however, does not always deal well with some of the disruptions of life and the ways in which life can pitch a curve ball. He does not see anything except happiness for himself and Catherine; he does not deal well with sad endings.
