Man, I feel for you gents. My wife actually gave me my CHL course as a Christmas present. Didn't complain when I bought my Taurus 9mm, the Crossbreed holster, the gun safe and boxes and boxes of bullets. She goes with me to the range and has even asked for a .22 rifle for her Christmas present this year. Sorry guys, she's mine forever.
As a pastor who does marriage counseling I've been very impressed with
most of the responses I've read. The best thing is to not make a big deal out of it, accept the eye roll and stink eye, and just be assured she will be thankful you have your CCW when it's really necessary. And she will love you for it....forever.
