I think you’ve done all you can. I’d carry on with my life. Tbh even if you told her everything she might or might not act quickly. She might or might not turn on you. People are funny about hearing the truth. If they aren’t ready or can’t handle the truth they will find a way to twist it. I wouldn’t say another thing to her about it. She isn’t your best friend or sister or child. You didn’t do anything to cause her harm. This really isn’t your burden to carry. You did what you could. The rest is up to her.
