Sons father

I am a single mother of an amazing boy. Yet his father was physically and verbally abusive towards me which resulted for me to kick him out around four years ago. Even though we are not together I feel like its toxic with his family towards me.., I had to block his moms number for what occurred in texts from her. A major issue for me is my son coming home from his dads weekends and than will act like his father did... I have heard of children witnessing abuse as a toddler and younger can trigger emotions in them like that when they start to remember? I am a survivor of domestic abuse from his father and still am being a victim from verbal and emotional abuse. Any of you suffer from PTSD because of abuse? And cant talk to friends or family members because they never been through it and feel at a complete lost?
