My wife is ok with me buying whatever I want as long as the budget allows. I get all the bills paid and her and the kids have everything they need and most everything they want. She see's no problem with me adding to my one and only hobby.
Tell her no such thing as too many guns or ammo then tell her to make you a sandwich.
New "Ole Lady"? Perhaps one that will let you make your own decisions about your stuff?
Told mine I could buy guns or use that extra money on hookers and blow.... She has no problem with my gun purchases anymore...
