What is going on with women who refuse to leave an abusive relationship? I am seriously starting to believe it is some sort of disorder. I don't mean to insult anyone or judge them. No one knows what someone else is going through unless they walk in their shoes. I am genuinely trying to understand. How can people help?

I have read your comments and I do believe you are coming from a genuine and probably concerned space. With that said, pathologizing victims/survivors? If you're asking why some don't leave, then may I suggest part of the answer is in your question. It's almost the same as enabling the abuser, imo.
I applaud and send hugs to all that have shared their stories here. My own experience really (sadly) opened my eyes to what a failure the court system can be, among other things.
Abuse doesn't happen in a vacuum. Who is stopping the abuser? Why not concentrate on how we can stop abuse and abusers from continuing as opposed to blaming victims. My two cents,
