If a person doesn’t want to take responsibility for the consequences of their actions, they may try to blame others. Don’t accept blame or try to fix things for them when you’ve done nothing wrong. They need to learn that if they want different outcomes, they will have to make different choices.
Imagine saying this, "I love you so much I will no longer disable you by enabling you. I am letting go of trying to fix, rescue, or save you. That is not my job. Never was. Never will be. Besides, maybe it's me who needed my help after all."
