The sad fact is that they’ve been lying to themselves. Consider going to Al Anon to better the disease & help you get away from the guilt.
I really don’t have any guilt about this because it’s not my problem. I am disappointed in my friend, and what she has done to herself. If I had gotten the kind of news, she got a year ago I would’ve done everything I could to change my life around. She didn’t do any of that. She kept engaging in the destructive behavior that brought on all her problems. At some point, I probably will confront her about some of these lies not that it will do any good.
