When you get your permit and she notices what a nice person you are when your carrying, she will request you carry more often.
When you get a permit and carry in public, many people need to change there attitude a bit ( being nice ) and she will notice that.
Mine kinda knew what she was getting in to because I've had guns around and on me for ever, ( before permits were required, pre 1975 ) .
Good luck, It will work out in a little time, other wise remind her of compromises "Like I haven't heard that" and this is is one of hers.
