It's hard to deal with this. You have the means to rescue her from her poor choices, as you've done, but she keeps making the same poor choices.
I rescued my BPD mother from her poor choices for many years, and she kept making poor choices. Finally, I didn't, and she was evicted from her home. From my view, that not being the consequence would have been easy to not be the result. From her view, another thing together. I could comprehend her view, even of I didn't agree with it, but I could only do so much before I had to let it go and let the chips fall where they did. She is an independent entity, free to make her own choices, as my T said about my Ex. I apply this to everybody now. It's not up to me to be The Fixer.
Natural consequences are the experiences that naturally follow a choice or behavior. For example, going out in cold weather without a coat naturally leads to feeling cold. Logical consequences are consequences chosen to follow behaviors that violate the acceptable behavior within a family or other group.
This may be hard for her to comprehend, that she's choosing to engage in behaviors which lead to logical consequences. However, it might be that she needs to learn this the tough way.
