See, it's difficult to buy gifts for longer term partners due to the fourth and fifth laws of femaledynamics:
#4: It isn't his money, its our money!
#5: It isn't our money, its her money!
Therefore, if you buy her something, it necessarily comes out of her money pool, which she probably had allocated already (even if you *think* you had a budget surplus):
(alternatively it might be "so is retiring when we are 35!" but since the economic downturn, she's reallocated all retirement funds to pay down existing debt more quickly)paraphrased convo of my married friends wrote: "Hey honey so I bought you this."
"Ugh! We have bills to pay!"
"but it is a nice gift for you"
"So is not paying INFINITE INTEREST on the mortgage for the rest of our lives!"
