Man, detaching is sooo simple. Once you get it. Note I didn't say it was easy. But it is simple. Simply stated it is The concept that because you cannot control anybody else, there is no need to let what they do have an effect on you. And all our friend here seems to do is watch her every move, and react (not respond).
My advice mirrors the others. Get away from this woman. She's bringing you down. She's a "bummer, man." I don't think you need to bust anything. Let her go. Obviously do whatever is best for the children. It's just that simple. Don't complicate it with anything. And how do you help the Children first. By putting your mask on first. Just like on the airplane! Put your mask on first then assist those around you. Why because you are useless if you aren't sane. And it sounds to me like you are a fireball of emotions and panicky reactions. Take a deep breath, focus on inner mindfulness, then protect the kids. Simple.
