This. Unless you can honestly tell me that you make no apparently irrational purchases. Coffee from Starbucks. Video games. Movies. I get it, you like them, they're convenient, and so they're rational purchases for you. But you can make better coffee for less money yourself, and you can be entertained for free. Compared to what you'll likely spend on these over the course of your life, compromising on a piece of jewelry your partner wants is nothing. If it makes them happy, be glad you were able to do that so easily.
