I'm going to sever contact with my entire family after the abuse accusation.
How will you feel if you sever contact?
It's sad that I'll lose connection with my entire family, but they started it with the finger pointing.
It's understandable to want to protect yourself from their false abuse accusations.
Never mind the accusation. They are assholes in general and I am walking away from them.
It sounds like you are making the right decision to cut your ties with toxic family members.
