My wifey and I figured out this money thing along time ago...it goes like this:
Whatever I spend on something is perfectly acceptable to her and I do not need her permission because, what ever dollar amount I spend, she gets to spend the same amount on herself and visa versa.
For you married guys that compromised who you were and what you liked to do early on in your engagement/marriage era, suck it up....you blew it. You must lay it out with your significant other so that they understand who ya are...this way, you can still enjoy the stupid stuff you always did before getting married and not have a pissed off wifey.
I used to spend thousands racing R/C Cars all over the US. When I would pull out for a race, my wife would give me a big wet one and tell me to kick their arses....my friends on the other hand, would be worried and unhappy because they knew they would be hearing about what they had done for years to come. and they always wondered why I won so many races...simple, no stress from home...I was focused:)
I have a very cool wifey:)
