Worldlygirl,
Your dad sounds like my father-in-law...except in this case there was a big farm to inherit. Finally, my husband got fed up and did as you did. When his dad told him he wouldn't inherit, he responded, "You know you're not going to have anything left for me to inherit anyway, the way you're losing money. I don't want it. Give it all to (hubby's brother and sister)" We've been gone 10 years and he still tries to manipulate. Fortunately, hubby is doing well in life and the manipulation and string pulling don't work (dear ol dad no longer has anything he wants, to use against him)
