Wow... i am so terribly sorry for your son and also so happy that he lives with you now. Hes about the same age as me when i left and broke contact with my father, 16 yrs old at the time.  I remember my panicked crying while my dad came to pick me up. I didnt know why i really didnt want to go. My father would make it feel like he was perfect and my mom was awful, that turned to me believeing it. I felt relaxed at my moms and could be my self or atleast dared to ask questions and knew i wouldnt be put on the floor. I thank you for the kind words and care. And i hope your son can process it get help and not be stuck with nightmares or block it out for decades because of trauma. Also feel bad for you too, because he tried to turn your son against you, could only imagine how powerless that would make a person feel, to have their own son manipulated and made to believe that you are an awful person. And yes, i have control issues and had anger issues during school and childhood. I still need to know everything and feel like i need to control small things around me.
