You don't have to confront your dad in an "attacking" manner to get things off your chest and out of your system. You can tell him that you understand he's changed but there are simply things you have had to deal with, things that are directly related to his past behavior, that need to come out in order for them to truly become a part of your past and stay there.
If you don't confront him and get these things out I can promise you one thing....your past will continue to rule your future.
