G, I don't think you're delusional at all. It sounds like your husband is either curious or courteous, and highly conflicted about what his future looks like. It's tough to deal with at times but you're already on a great path; this trip is an example. You're doing something for yourself, not wallowing around in self-pity and creating stories to tell people in the future. Stay patient, keep your interactions with your husband light and be grateful for the interactions you do have with him. Enjoy the rest of your trip!
