I lived with a woman for 2 years, we will call her "economic". Everything I bought, no matter for myself or for her, was expensive, and I was a tranche.
The barrel just opened up. Most likely, she had not a very rich childhood, she a) used to the need, it is forever, nothing is corrected, even 40 years of full and cloudless life; b) she used to always and in everything rely only on herself. I just had to give her money! And to say - "choose yourself, you know better what to do and what to do!"" She was uncomfortable and even ashamed that someone was buying something for her or for her. Not everyone has had fun since childhood.
