I think the way I'd put it is that he seems like the sort of person who never admits that he has feelings, least of all to himself. Because those make him vulnerable, and being vulnerable means he's weak, and he can't be weak ever.

Least of all where it deals with you, probably a few other folks back home. He's... uh... kind of easy to read, no offense. You both are. You wear your feelings on your sleeves.
