Dh and I have been having money issues the last few months. We rum completely out of money for the last week or so of every month.
I have a credit card that I use for emergencies during this time and to buy basic food. I refuse to let dh borrow this card at all as I want to have complete control over it. It is our only source of money if there is an emergency. So dh has no money at all for the last week or so of each month.
Also to add, my parents gift me money every now and then that I secretly use to pay off the credit card. Dh doesn't know about this, and this is another reason why I'm so protective of it.
