So first off will confess to name changing for this post, but please give it to me straight. I really go back and forth in how I feel about this and need AIBU right now.
My father was an excellent father when I was growing up and we became very close. Five years ago he entered a downward spiral - became a raging alcoholic, had affairs & eventually left my mother for one, alienated lifelong friends horribly (ie. violence, threats, etc.), he lies whenever he is awake, vicious lies that ruin lives. He started using drugs (has since stopped this he says), met new "friends," ruined his life in every way you could think of. I have been the only one who has continued to stand by him and try to get him to fix his life despite ongoing verbal/mental/emotional abuse. The rest of the family has nothing to do with him, and I don't blame them one bit; he is toxic and has no sense of right and wrong anymore - he would do anything to anyone and not feel bad. Suffice to say that while I have tried to "do the right thing," mainly because he was a great father for 30 years or so, I have done it in absolute terror and it has taken it's toll on my health and other relationships. I have lost many friends over things he has done in our community, and still been the one to pick up the pieces each time. I would not repeat any of it, but it is shocking how cruel and intimidating and manipulative he has been.
Then I had DS. This has changed how I feel about many things. I feel that I unequivocally cannot expose him to a threat of danger (not specific atm, but could be on any given day when he "loses it"), or even the negative influence. I am ashamed to admit it, but I think I would like to cut my father completely out of our lives. I feel like a horrible person even typing that, which I guess is my AIBU question.
I have always thought that family should never give up, never cut each other out. Now I am wondering if that was a bit idealistic on my part. Is a horrid thing to think? AIBU to cut my father out of my life?
