Your dad was also responsible for breaking your arm - period, no equivocations. He was also responsible for the fall down the stairs and it also may be that he is responsible for provoking you into acting out.
Take care of yourself since you are starting to relive this stuff in your dreams. It's good you have been able to post here. If you find that at some point it's enough and you need a break, the forum will be here when you are ready to go at it some more.
Meanwhile, I'm glad you talked to your sister - it may not have seemed like the full conversation you had in your head, but it's harder in reality. You did great.
