Because I think many times in relationships, girls have to pay a part, and now they all advocate equality between men and women. Many women have their own independent careers and their own unique values. If your girlfriend is stingy, then your girlfriend may choose to let you spend money in many ways and make many unreasonable demands on you. I think this is very terrible. You should discuss it with your girlfriend.
Of course, don't be too straightforward when discussing, because it will hurt your girlfriend's self-esteem. Maybe your girlfriend is just testing you, because sometimes a girl can be stingy to see if this man really loves himself. If you are too irrational, it is likely that your girlfriend will find that you are not worthy of her love, so you should have a good communication with your girlfriend at this time to see what her real values are.
Of course, if you meet a stubborn and stingy Taurus girl, I think you can consider breaking up, because many times a stingy girl often makes her boyfriend feel pressure, and it will be very terrible in her later life. Some unreasonable demands will make your boyfriend breathless, so you should see if you can really be with your girlfriend, otherwise it will only make your life more and more sad in the future.
