To the OP, I'm so sorry that you and your daughter are dealing with this. And whether her father is being abusive due to addiction/alcoholism, brain tumor, insanity or is just a garden variety glassbowl is irrelevant. Abuse_ is_ abuse and you are doing the right thing by taking action to protect her.
And a PSA reminder to all: we never know who is reading these posts. Perhaps exes with vendattas, stalkers, those with control issues trying to find someone. Be safe when sharing information and when someone PM's you on this board.
