I almost lost my dad this year to a heart attack. He and I have had an up and down relationship, mostly down due to me never doing good enough for him. But it was eye-opening when he had his heart attack how all of that melted away. For the first time in my life I saw him in a vulnerable state and although a tiny part of me wanted to throw back in his face all the things he's said and done to me over the years I just wasn't able to. I saw him not as a dad but as a man. Someone capable of making mistakes. I didn't really forgive his actions but I was there for him when he needed it. I let him know that I would take care of my mom and the house if he wasn't going to make it. Let him know that for all his faults and mistakes, he still raised a man. And that's about all you can do for your father. Just let him know in his heart that you are in a good place in life and will make him proud if he doesn't make it. If it's destined for him to not make it then don't let him pass on thinking he failed in being a father. Any hatred you may have needs to go away. Make this horrible situation easier for him or else you'll always regret it.
I wish you the best and good luck.
