My wife and I have a pretty good system. We pay all the bills at the end of the month and fund our investments. Anythinhg left over gets split. However, we've reached an agreement on new gun purchases. The safe is full and guns are chained to the bedframe so we've run out of room. If I get a new gun, an old one has to go to make room. Same with her shoe and purse addiction. Yep, give and take make it work.
