So many nasty, shameful responses.
OP, I cannot imagine the grief you must have experienced loosing your husband so suddenly.
Your poor husband must have turned in his grave at the sheer awfulness of his family.
They sound utterly and completely ghastly.
I completely agree with your decision to not give them ownership.
Such dishonest people would replace your headstone in a minute and write you out of his life.
I would absolutely question their love of him and how genuine it was.
If they truly loved him, they would have absolutely wanted to honour that love, by treating his young wife with compassion and understanding.
THAT is what decent people would have done.
I don't believe that kind parents, BEFORE he died, would suddenly morph into awful people after his sudden death.
I think you should wisely judge them on their past behaviour and their duplicit underhand actions.
Wishing you the very best.
My darling grandmother lost her precious only daughter a year after she was married.
It broke her and my grandfathers hearts.
They remained in contact with her lovely husband and my Gran was happy to see him remarry some years later.
I remember her telling me that the pain never left her and him meeting someone else meant it had ease for him.
Her daughter had loved him so much, he was so loving towards her.
How could she, as her mother, not wish happiness for him, the chance of love, and a family.
It would absolutely be what my gorgeous aunt would have wanted.
My grandmother was a wonderful woman.
