WELL THE SH*T HAS FINALLY HIT THE FAN HERE....
I would be very prone to calling the police to be there when she is scheduled to pick up his things. Tell them you are afraid she might get physical. It gives you a great witness if she does get weird and it also lets her know you are not going to stand by and take this in the shorts! I'm with the post on the HIPPA law as well. I cannot see how she was able to get any information from the therapist unless dh approved it. If he didn't, the therapist has some big questions to answer if she was involved! People talk all the time about getting divorced and never do a single thing about it. Saying you might and actually initiating procedures is two entirely different things! The reality is, she is getting to find out for herself just how "sane" good old Dad is. Get the lawyer and go for it! Good luck!
