As the story M+M ends, what does Martin imagine himself doing when the war ends?

Martin imagines that “when this—all of this—is over” he will return to the school where he and Mariela met, imagining that Mariela will be there, even though he knows Mariela and her father were attacked by the communist rebels. He imagines that neither of them will speak, saying he won’t listen to her when she says, “Why didn’t you tell me” (87).
