Hi. He needs your forgiveness for his weaknesses as a father. I can Fully empathise with your dilemma. But he now knows his own weakness and cannot overcome that unless you intervene. I am sorry for your loss. I am sorry for your father. He is the one that needs help now, as I am sure that you are a better person. You need to do this for both him and yourself. And trust me.... I do know. Best of wishes
