Yes. I care about money a lot. And it's one of the problems with my boyfriend. He spends money left and right on movies, electronics, and beer. So to keep everything straight. I have my paycheck and he has his. We have separate credit/debit cards and pay for our own car insurance, cell phones and split the bills. I pay rent, he pays for utilities and upkeep. I also pay for vacations.
I keep control of every dollar I have and count every penny.
