I would tell her that you will no longer bail her out. I would offer to pay for her to take Financial Peace University if it’s offered in her area – go to
www.daveramsey.com It’s also offered online I believe. This is a wonderful program taught by a man who went through some devastating financial times of his own making and his fight to get out of that debt based on Christian principles. If she refuses that offer, then she’s on her own. You can give a man a fish, and he’ll eat for a day. Teach them to fish and they eat forever…
I used to think my parents were unfair that I basically had to work my way through college. They helped, but I was expected to pull my own weight. As a fully-functioniong adult I now appeciate those lessons.
