OH YES! I posted this in another thread. I totally get this.
Yes, two of my sisters both have "sided" with my abusive alcoholic father, deceased. One says it was my fault getting beat, for not being smart enough to get away with not getting hit and the other one says it never happened. This is not an easy disease, and it messes up families in so many ways. Now that you know, it can be more easily dealt with. Good luck.
Oh and by the way they are both terribly wrong. My 3 other sibling and I were beat mercilessly by a drunken father for no reason, even waking us up to be beat. They are both estranged from the family by their own choice and don't even get along with each other. Sad.
