Secret = BAD DOG NO BONE! I will start by saying that there is a reason I am on my 2nd wife, but my advice would be just to tell her that you've come to the conclusion that one of the actions you need to take to meet your obligations to protect her and your children is to learn to use and have a firearm. That's the way it's going to be. Now be prepared to pay the price for that, and keep in mind that the price may very well be not only your marriage, but your kids. Because if you live in a liberal area her accusing you of being a bad parent because of the guns may fly. It wouldn't in my area, but I don't know where you live. If it flies there, then some judge may take your kids away and you'll NEVER see your kids again. So, if it's worth that risk to you then go for it. If not then start a long slow sell on the idea. And, sometimes that doesn't work, but it's really your best option.
