Congrats !! It's nice when they come to the decision, even if it's in their own time.
I got my CHL in 2004, it wasn't till last year my wife said she wanted her CHL, She even wanted to pay for the class herself. Then she hopped on the bandwagon and got her PA license as well, since her parents live there. Finding a firearm for HER was a bit more of a challenge, she can shoot all of mine but didn't really like any of them so a borrowing and a renting we go until she finally decides on a S&W M&P 9c after shooting one at the range. Now that we had a decision I bought it for her for Christmas and made a holster to go along with it.
Another recommendation would be to get her a copy of the Cornered Cat.
(there is also a Website
) a book geared towards women who carry, it covers many topics and issue that women may have that men don't. Difference in the shape of our bodies and how it relates to carrying concealed for instance.
She has also agreed to go to an advances handgun class with me this summer, which is great, because the CHL class and time on the range really isn't the same as quality training.
Glad your other half is joining the fold
