So having heard more... yes, something happened. At least I would think so. What happened? No idea. Probably pretty traumatic, whatever it was. Perhaps caused a psychotic break, perhaps she's schizophrenic (where's willravel when you need him?), perhaps it's the anxiety/OCD blowing up...
The point? If you want to help her, a therapist who is not a psychiatrist isn't good enough. She needs someone with more experience and knowledge of heavy duty psychological trauma. And soon. Because it's pretty important to know just how dangerous her ex actually is - if he is, she needs to be safe. If he isn't, HE needs to be safe.
Just because she handles the rest of her life well... doesn't mean she isn't suffering from a trauma/trauma induced psychotic break/whathaveyou. It could, but it's doubtful.
Ask a professional yourself and see what they say, get some advice from people who aren't armchair psychologists (like myself, sorry.
)
