When I didn't give in to my boss's threat either, and instead kept Mary, he was then forced to fire me and create the window of opportunity Trish needed to move in and finally separate Mary from me. Not having a job at the time, nor a place to live, meant the girls had to stay with their mom for the few weeks. But they've never returned, and I no longer see them. And I think this is what Trish wanted. I think she has wanted this for a very long time.
For both Karen and for Trish to be this well-coordinated on a plan this risky, at the same time, for the same child, and for the same reasons, tells me they had a plan in place long before I lost my job. It wasn't Mary's plan, and it wasn't a coincidence.
