I'll put it this way... a wife turned on her husband who had arsenal enough to arm everyone on the block, cops not only took everything he had but arrested him and charged him with a list of things. She felt "threatened" by his prepping stuff and firearms. Maybe he was delusional maybe he wasn't. But your own wife? Ouch. If I remember right that was some cat in NJ. There are some cases of this across the country, not publicized in the mainstream media more a 5 second chirp from local media.
Some people are ok with it, some people aren't, some people don't mind compromise, some people won't compromise... just find someone you trust and who trusts you and (at very least) appreciates firearms for defense even if they don't want to head to the range with you.
