It isn’t your fault if others don’t understand.
If she keeps asking the same questions maybe she thinks this is just a phase you’re going through. I’ve read other SO’s at first think its just temporary and I believe my wife thought the same thing but they soon find out its not going away and they realize the long term affects. Some can deal with it some can’t. I recommend you both get into counseling and on the same page with a therapist that understands our lifestyle. If there is anything there she will try to understand, if not, then move on and consider yourself lucky.
