wife of a veteran

Alex

my husband is a veteran and was honorably discharged before I met him.

i want to talk to him about his experience and all but I dont know what questions to ask. (he has asked me why I dont talk about it)

I dont want to seem uninterested but I just dont know what kind of things to ask without seeming pushy to know more. can anyone help me out? I want to know as much as he can tell me but I cant seem to get past the broad question of "what happened?"
