Dear Eric: My brother has children with whom I was extremely close when he and his wife got divorced in 1989. He never supported his kids, never paid child support and drank away everyone’s money, including $20,000 in rehabs that my parents paid for.

My brother asked me if he could borrow $5,000 and he would start making payments to pay it back. For the sake of my niece and nephew, I loaned him the money. Unbeknownst to me, my brother was borrowing money from everyone in the family. Soon, everyone in the family found out what he was doing and cut him off.

Fast-forward to three years ago (I’m now 56, and my brother is 72), he reached out to me again. Not to borrow or pay back money, but to reconnect. Through our limited conversations, he keeps asking for my address or an invite to my house. I never extended the offer and I did not give him my address.

Brother recently told me he has been sending $200 to $300 every couple of weeks to my niece, now 40, a divorced mother of one son. He is also putting several hundred dollars a month in a trust for her 9-year-old son. I told him, on several occasions, since he has money to spare, he can send me money each month to pay me back. He laughs and blows me off.

I’m extremely ticked off that he disregards the sacrifice I made.

I blew off my brother and the $5,000 years ago and I don’t care to rekindle relationships that have been dead for 35 years. What I want is the $5,000 repaid. I have two kids in college and I’m partially retired. I’m not charging him interest for the past 35 years, but I should. I don’t think I can be blunter with my request, nor because of the time that has passed, would I have legal recourse.

If you have suggestions, I would appreciate the help.

Dear 5k: I hate what I’m about to write ... you have to let it go. The $5,000 has grown so large in your mind, fueled by the compounding interest of outrage on your part and unreliable behavior on your brother that it’s nearly impossible to pay down.

Ideally, he would pay $5,000 plus 35 years of interest, but that’s not going to happen. He has, inappropriately, laughed off your request. It hurts to be used like this and it’s not fair. But this is who your brother is.

You blew the money off years ago, but these emotions are coming up now because there was probably a part of you that thought by lending the money, you were helping your brother become a better person. It’s possible that that’s still true.
