I'm in the unique position of being in the middle of a bitter mother and and estranged daughter (because of what she's been told by my mother). The upside of this is twofold. 1. I've left them both to their own lives and gone off to make my own life. 2. I can see things from both sides.
So yes, I can agree with all those parents who have been treated badly by their AC resulting in them being disinherited. I can fully understand all the hurt, betrayal and pain that made you take that decision. And I agree, they deserve nothing if you've been driven into taking this action.
On the other side of the coin, I think it's just money, we won't be needing it where we're going, and I wouldn't be able to look down from the clouds seeing my daughter in dire straits and hurting because she thinks I never forgave her for the rift. I'd want her to know that I loved her more than I was angry and that I'd left her enough to see out her own life.
It's just how I see things but I appreciate the views of others may differ and that's OK.
