Which unfortunately allow people to choose to continue to place themselves in that situation.
Point of order on this. It's a lot more complicated than that. When people build up dependency, in the way that these relationships create, they have to
want to escape it to change. Just taking someone away from that situation doesn't help. Oh, in the short term, maybe it might. But in the long term, all you're doing is subjecting a person to a more elaborate form of psychological torture by removing the anchor stones that they've built themselves around out of necessity. That sort of mental construction isn't healthy, no, but you can't just rip them down and force someone to build new ones without being literally just as bad as the person who made them do it in the first place.
Whilst it's undeniable that on some level every person dependent like this
wants to escape, humans are exceptionally good at deception when it comes to our own feelings. We force those feelings down, lock them away, and throw away the key. Once that's done, the only way for someone to
healthily free themselves is to deliberately seek out those parts of themselves. Abuse survivors never survive as the people they once were. They're never whole again, the mental and emotional trauma leaves its mark as firmly as any physical scar. But the difference is that in the field of mental and emotional wounds, a person has to
want to heal to get better.
It's why breaking someone on the inside will always be so much more lasting and effective than doing so on the outside. And yes, that's not nice. But it's also human.
