It's very rare to get a real diagnosis of this disorder. Sorry to hear that you've been dealing with it. The full-blown disorder is really tough to handle. We've had several threads addressing it in the past year or so... about 2 years since we got the diagnosis...
Getting the diagnosis, my husband & I started reading up on it, and it just explains SO MUCH. It makes things easier to take (a little) when we understand her motives are totally based upon HER. WE just hope the kids are not getting too sucked into it, because they live with her most of the time and her motives have been to punish her ex by withholding the kids, and she's got the kids on board using various methods... most recent is punishing them for seeing him by not allowing them to drive the car when they're coming to see him... the car he paid for, for them. THEIR car.
The ONLY reason we don't see more severe PAS out of the kids is that they had a really strong relationship with thier Dad before the split...
