Well, interesting, my parents tell me the opposite that they will never leave me anything no matter what. May be, because they don't have anything anyways. Thus, I do as I please. But, to get to your point, using money against you to make you feel inadequate is emotional abuse. Do you really need your father's money? Is he a really old man who is going to die soon? If you think he will live a long time from now, then in reality when are you going to inherit his money. I would not be affected by his threats of disinheritance. I would find a way to be on my own if I were you and be free from such abuse.
