I'm so sorry, Betty.
My father was like this often as well. He would give us hell for knocking over a drink at the dinner table. He's still giving my brother sh!t simply because he's rather uncoordinated. We all walk on eggshells around him. He can be such a monster.
I don't know if divorce is the right option for you or not, but whatever you do, be strong...and perhaps if you confront him with what you've been thinking for months, maybe he'll wake up a bit...although it didn't work for my mom.
When she said she wanted to leave him he cut up her atm/credit cards and took her checkbook away. No joke. She got them back years later, but still...
