<human>: My husband has known his best friend, "Charlie," since they were in preschool together. Charlie married "Jenny" 3 years ago. I've known Charlie since I met my husband 10 years ago, and I've known Jenny since she met Charlie 5 years ago.

Charlie has always taken some liberties with the truth. I recently learned from my husband that he is not being honest with his wife about their finances. Charlie has a great career and makes a ton of money, I think over $150,000/year. So his wife doesn't work a paid job, she volunteers at an organization that's important to her and plans to be a SAHM when they have kids (they have struggled with infertility).

Through a combination of bad luck and bad decisions (bad investments), Charlie has lost most of their retirement fund, and gotten behind on the mortgage. They bought more house than they could afford and now it's catching up to them. 

Jenny is pretty spendy, not in a bad materialistic way, but she apparently has no concept of their financial situation, and Charlie never tries to stop her. (I think a lot of it is guilt over not being able to give her a child yet.) Charlie admitted to my husband that their monthly cash flow is negative right now.

The only person Charlie confides in about this is my husband, and my husband confides in me because he's really worried about Charlie and Jenny. I feel like it's none of my business, but Jenny deserves to know what's going on. My husband's first loyalty is to his lifelong friend, not to Jenny, so he will never tell her what's going on.

Should I butt out or do I have an ethical obligation to tell Jenny what is happening to her financially?
