That's kinda fucked up that your father would give his trophy wife everything and not his kids.
If I ever got remarried I'd still put my kids first.
She's hardly a trophy wife, LOL. But I guess she is in a sense. She's 12 years older than me and 12 years younger than him. If he didn't leave her everything, she'd have nothing. I suppose there will be 'something' for us. But I'm not counting on it for 2 reasons.
1. She will need the $$$ to survive. She's too old to work, and she ran his business, so she's 'owed' something in retirement.
2. They had a kid together, and that kid has all sorts of issues. I won't get into that, but while we all get along with our half-sib, let's just say she can't take care of herself in any reasonable manner. So part of giving the cash to his wife is because then it can be put in a trust for her.
The rest of us are all successful. As fucked up as it seems, it's not really as fucked up as it might seem.
