Unbalanced Inheritance Division

[Stilson]

I'll keep it brief, my parents both died some time ago, and I can't get over this.

The estate was split with 20% going to me and 80% to my sister. She gets £160k I get £40k.

Both about the same age, both been a part of the family equally, she is wealthier than me by a large margin.

I want to cut all ties as she refuses to balance out the amounts, even a 60:40 split.

We're it the other way round I would be uncomfortable with the settlements and would rectify it, she won't.

AIBU?

Just to say OP I know how this feels and it harder than most can appreciate if they haven’t been in this situation. Sending love your way. It’s a really tough hand to be dealt

And OP is also valuing money over her relationship with her DSIS. She's literally cutting her off because she won't give OP a huge chunk of money she's not entitled to. If OP valued her relationship with her sister she'd just accept that she's only entitled to what was left to her in the will and move on.

Look at it the other way. The other sister would rather the money it seems,even if the unfairness of it all is destroying her sister 😔

This is entirely performative. Why would anyone value a relationship with someone who values money over them? MN always says people show you who they are. If OP wants to protect her boundaries and doesn’t want to have to re-experience the hurt of her parent’s and sister’s values and betrayal that’s ok.

Bitterly trying to twist it to use it against the OP for your ends is hypocritical.

Nope. Both sisters think the money is more important than their relationship with each other. OP doesn't have to try to get her sister to hand over chunks of money she's not entitled to, and OP's sister could choose to gift OP a large chunk of money if she chose to. Neither sister are prioritising the relationship with the other over money. They are equal in that respect.
