Thanks for the nice thoughts.
I understand if you need to talk to your dad for business reasons.
Another thing I have learned here is you don't need to tell the other person your boundary. Chances are, if you do, "I am not going to talk to you anymore 'cuz you are abusive" - type of thing, it will cause more drama.
If you want to type up your loose ends and be done calling him or answering his calls, that is legit.
You can't reason with an alcoholic.
You can't get the to see.
You can't get them to get it.
It's phenomenal, really.
I have tried a million ways from Sunday, but they are in THEIR world, and they have a right to be.
So, what I have heard here is if you need to tell the A a boundary because YOU need to say it, then go for it.
If you are telling your A your boundary so they can have one last chance, or finally understand, or whatever, it won't work.
The work is just to enforce the boundary and let them do what they need to for them.
Hugs, peace
