My spouse and I met at work. We worked in separate groups, and were on the same floor, so we saw each other constantly. We had a lot in common, and I was able to use that to my advantage!! :D
My wife is intensely frugal, whereas I don't sweat the small stuff. You could say that she is penny-wise, pound-foolish and I am penny-foolish, pound-wise. So we meet somewhere in the middle and I think that has a lot to do with our financial well being.
She handles the day-to-day bargain hunting, coupon clipping, etc. I allocate our money, track our finances, plan our retirement and handle our portfolio, although when I buy stocks, we sit down together and discuss the companies. It sort of works out that she is responsible for maximizing the cash we have on hand, and I am responsible for taking that cash and growing it.
I think we've both converted each other a bit. Before, whenever I saw a stray charge on my bank account or statement, I would just let it go. But now, I call them up and argue with them until they reverse it. Also, we are debt-free and I am in the habit now of paying off the monthly balance. I am also very good about paying bills promptly (which I never was before meeting her). I also find myself looking more for bargains, such as deals or buying used.
With her, she was always very risk-averse. She didn't understand stocks and if she had her way, we would be stashing our money in coffee cans buried in our backyard. But over the last 10 years, she has seen that the stock market and real estate can be wealth building vehicles, as long as they are used wisely.
I think this middle of the road, constant push-pull between us has kept us on the right path to financial freedom. I wouldn't want to be traveling this path with anyone else! :)
