There's probably more to the story. I dont buy that a rich man would be the lover of a minor of the same sex so easily. Thats instant jail time.
Some rich guys do that sort of thing, dont get me wrong. On the other hand, you leave your money to your wife, kids, family.....your blood IMO. Not a lover. Sorry.
Props to that and BIG PROPS to the Surfer's answer. I don't know how it could even be expected that he would leave the jump-off anything in the will. That rarely happens.
