I am new to this realm of carrying. But, I find it imperative my wife learns to shoot and carries something. After finding a 911 call on this site of a lady home alone and a man breaking into her bedroom during the 911 call, shooting him, and killing him while still on the phone as she was being strangled- I sent it to my wife's email at work... she came home and said...
" I want a gun. "
It totally changed her view to actually hear a real life situation of a female alone, with nothing to protect herself, no man, no sons, not even a locked door, and locked up house... but the gun saved her.
I am 21 and a newly wed... but if you can research instances for your wife to read or hear, and it may deter her natural instinct to feel as though nothing can happen.
