Welcome aboard.

So the thing you have to ask yourself is, are you a man or a mouse. It's a very common issue with women they think they can spend, spend, spend on themselves but the guy has to account for every penny. My advice is you each set up a discretionary fund where you have your own money to with as you please that way you can buy your razor gear and she can buy her stuff. It also cuts down on money issues which can wreck a marriage.
