Oh boy. I'm sorry for you. I hope she is taking her medications, but if not you might need to think about an alternative to maintaining that relationship.
I've had the cutest boy with me all week, but as you said, the other shoe did indeed hit the floor. His mother is making his guardians life a hell and I keep telling myself murder is not allowed here.
Stress levels in the roof. I'm tired and so fed up with people, and them my own son kissed me good night and said it's really great we have the baby with us, and that he'll figure out tomorrow how to fix its brain damage.
I'd do a week like this all over to get a comment like that again.
