Ain't too late to get another wife.
Seriously though, my wife of 45 years has never fired a gun, doesn't like guns, and is not thrilled when I carry one. However, I told her from the getgo that I liked firearms and would be acquiring a few in the future.
75+ guns later she hasn't budged but doesn't give me any flack. Of course the custom jewelry bauble I buy for her each time I get a new gun might have something to do with the peace.
