I am sorry you had to go through that, too. When the pain they inflict is worse than the pain of cutting off contact, there is no other choice.
LOL, the reason I use "GoodEnuff" is because with them, I am never good enough. Tried for most of my life until one day I realized that I didn't have to meet their demands. Not perfect but definitely good enough.
Hugs to all who have been through this in their lives.
