Suzzie, I can just imagine you as a child looking at your dad and trying to figure out why he was doing this. Children always come to the conclusion that they must deserve what is happening.
I'll bet 100% that your dad was sexually abused as a child. Many people who were abused as children would never hurt another person ever but there are those who go on to abuse others as a way to deal with what happened to them. There thinking is that the only way to not be a victim is to be a perpetrator. This does not excuse his behavior in any way.
I'm so sorry that this happened to you Suzzie. You deserved to be taken care of by a healthy parent.
