Abusive Son

My 35 year old son is repeating the abusive, narcissistic patterns of his father who I divorced after 35 years of marriage. My son is focusing his resentment towards me with episodes of rage. I’ve been in therapy for five years so I know when I’m in danger, physically and/or emotionally, so I’ve reached out our local domestic violence counseling group. I also know I have to cut ties with him to stay safe but that also means cutting ties with his wife and my two grandchildren. She’s knows he’s abusive but isn’t at a place to seek therapy or leave and he uses the grandchildren to hurt me. I need prayer to remain compassionate while still standing in my power to not accept his abuse. Pray that both he and wife reach for healing and someday find peace.
