Question

So I have a friend that’s constantly asking me for favors to bring her stuff. We stay like 5 minutes away from each other, but every time she asks me to get something she never pays me or when she asks to borrow money she never pays back. I was trying to help her out, because she is a single mother, but at the same time, I don’t have money just to give her and every time I ask, she gets mad, and the thing is, I don’t have a car right now. She has one, so I’m like, why can’t she go get the stuff she wants herself? I think she just wants me to spend my money. I’m thinking about cutting her off, would you?
