Not being contacted on Sis death

My only sister died last week - my niece who forbade me telling her of our brothers demise - have another post on this dilemma ….

So disrespectful and callous that I wasn’t informed

To add to this shocking announcement -my nephew offered his condolences to me thinking I was informed and in my state of hurt, I told him I wasn’t allowed to tell Sis, our brother had died ,

I now know, my SIS died on the funeral date of our brother😢 Life can be so cruel but I can’t forgive my niece for not allowing me to share this passing and to not inform me about SIS - am so hurt
