Money 💰

I need help managing my money lol. I work full time but I have to help pay rent and internet bill and I'm trying to save up money too. I want to buy a $40 curling iron because I don't have one but I feel like I shouldn't. I feel like my bf might get mad because I'm wasting money on myself. I never get him anything but he does get me things. But I could never ask him for something so expensive, not right now. So to buy the curling iron or not to buy the curling iron? That is the question lol.
