There are tons of things we would have done differently.
First and foremost, treat him like an adult. Addicts exhibit childlike behavior. Our trap as parents is to treat them like they are acting, not like the adults they are. That’s enabling and not helpful to them our us.
We caused ourselves tremendous financial problems bailing our son out of the financial messes he got himself into. That’s in the top two of things I’d advise parents to never do. I’m a financial advisor by profession. I know better. Yet we went down that road and it cost us big time. It hurt us and enabled him.
We let him, his wife, and her son (8 or 9 at the time) move in with us. Never should have done that. I can’t even get into the problems that caused.
Parents need to protect themselves from their adult son or daughter’s addiction. When we first discovered it, things moved so fast and furiously. That’s when we made the worst decisions.
