Oh op. I understand.
same situation here. My parents are leaving all (not massive) to their 8 grandchildren. My aunt and uncle - no kids, and due to family rifts I am the only one who had any relationship to them, did all the caring etc, managed the Poa, was executor and so on - left it all (considerable) to be split between the same 8 children, mine being the only ones they had ever met.
so a generation missed out completely.
My siblings are all married, good jobs etc. like you I am on my own. Have an ok job but nothing major. So on my own for retirement etc.
logically, of course, it’s their money, they can do what they like etc etc. but emotionally, it’s a gut punch. I just felt so….unvalued. Rejected. Like everything I’ve done for them (which is loads) is completely unappreciated.
still feel it tbh. so really feel for you.
i don’t know how we get past it. Suppose focusing on the fact that at least the kids will be ok. And we can spend what we have on our own retirement, knowing that the kids are provided for.
I’m actually going to talk it through with a counsellor someday. See if that helps.
anyway, that’s not much help to you except to say that I understand completely, it’s the emotional side that hurts x
