Honestly, I dont think there are any questions I could have asked my ex that would have lead to any insight or forewarning. She sometimes acknowledges that she has mental health issues, but leaves it as a simple statement of fact with no intention of doing anything about them.

In her mind there is absolutely nothing wrong and it is simply everyone and everything else in the world constantly against her.

The only possible answers I could get from her would be why any given crisis is my fault, or her family's fault, or the world's fault. And she isnt even exactly lying, because in her mind that is exactly the case and any attempt to get her to see things from another point of view will simply make her violently defensive because you are siding with them against her.
