I'm not sure specifically as I haven't read the story. But it could be secrets about the marine's life away from home, like the challenges he faces in the military that he doesn't share fully with his wife. Maybe secrets about their relationship during his deployments, such as how she copes when he's away.
The secrets could be about the emotional challenges she faces while her husband is away on marine duties, like dealing with loneliness and fear for his safety.
Self - discovery could also be a theme. As the husband uncovers the wife's secrets, he may also discover things about himself, like his own capacity for forgiveness or his own insecurities in the relationship.
It could be secrets related to the military life that she has learned through her husband. Things like the unspoken rules or the real situations on the battlefield that her husband has hinted at but not fully disclosed. And she has to keep these things to herself for various reasons, like national security or just to protect her husband's comrades.
Perhaps the secrets are related to her inner thoughts and fears. She might be secretly terrified every time she hears about military operations where her husband could be involved. Or it could be that she has a secret support network that helps her through the tough times, like other military wives who understand her situation precisely.
