I'm thinking of selling the rings, is that wrong?
It depends, do you need the money that badly?
Yeah I have to, otherwise we will not be able to eat.
If you need to sell the rings for food, you should. Material things should not take precedent over your health.
I'm going to sell one of the rings to help pay her dentist. I'm going to sell the other one to help pay a bill.
Who ever purchased the rings will understand that you need the money for more important things, so do not feel bad for selling the rings.
