I need some good advice! So I work just on weekends and stay at home with my son during the week. I work in weekends to save up money to make payments to my car that I wanted extremely bad and have been making payments and even saved to where I have extra in my savings to add towards my car! And my husband, without asking me, took out a ton of money to pay off one of his credit cards that he had before we were even married that he put fishing stuff on! I wasn’t happy obviously seeing my hard work go towards something like that! But when I said something to him he said he works while I stay home most of the time and it’s our money and it’s a bill that could be taken care of for good but I’m seriously bothered by it! My car doesn’t have much go to pay it off cuz I been working crazy hard to get it paid off as soon as possible!! So I don’t know what to do or if I shouldn’t even be bothered and if he is right cuz I don’t know sometimes I over react! Lol
