i have a dear friend whose sister was murdered last year by her ex-husband of EIGHT YEARS. messy, horrible divorce, lots of psychological abuse. obviously he had problems moving on, so to speak, and his brother convinced her to attend counseling with her ex. after 8 years, she thought it might help, and so she went.
rule was she got to leave the session 15 minutes ahead of him----but the last time, the counselor let him leave sooner because he thought things were going so well.
so he goes outside in the parking lot where she's getting in her car, and shoots her dead.
that's what counseling with a psychopath gets you.
ETA: i didn't say this right-----they were married for 15 years and had been divorced for 8 years when this happened. apologies.
