Dear Dave,
My wife and I are debt-free, and we live on a budget. My mother-in-law, on the other hand, uses credit cards for practically every purchase. Several times she has gone too far and run up balances she couldn’t pay off. We bail her out when she does this, but often the extra purchases are frivolous things she doesn’t need. We love her, of course, and we feel obligated to help because my wife is her only child. But her behavior with credit cards is beginning to put a strain on our finances. What should we do?
