You are very wise to leave it alone and allow the man upstairs to handle this. In the past, when you have stepped in, he has always managed to slam dunk you. Now, he doesn't know how to deal with your silence and inactivity. He's got to screw this one up all by himself. He has always been insecured, thus the bully tactics.
As for your daughter, she's stronger than you think. Your son is no longer under his control, therefore, he needs to find another avenue of control. I wonder what will happen after your daughter graduates...who then will he have to beat on?
I do hope that you are taking care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
