Sometimes the greatest act of love is refusing to help someone continue destroying themselves.

There is a point where continued help stops being help and becomes the thing that makes a harmful pattern sustainable. Stepping back in that situation is one of the hardest things anyone does, because it looks like abandonment and feels like it too. It is not the same as giving up on someone. It is refusing to be part of the machinery.

Ask honestly whether what you are providing is easing a crisis or removing the consequences that might create change. Get advice from someone outside the situation, because it is nearly impossible to judge alone. And take care of yourself in it, since this kind of decision takes a real toll.
